Introduction
Gibraltar’s Trusted uPVC & PVC Window Specialists
Why Professional uPVC Repair Defeats Heat Warping & Coastal Wear
Unplasticised Polyvinyl Chloride — uPVC or PVC — windows are highly popular across Gibraltar’s modern developments from Europort to Ocean Village. But Gibraltar’s coastal microclimate pushes plastic frames to their physical limits in ways that generic DIY guides from overseas are wholly unequipped to address.
The intense Mediterranean UV radiation that blankets Gibraltar for the majority of the year subjects uPVC profiles to severe and repeated thermal expansion. During peak summer heat, a white uPVC frame can reach surface temperatures exceeding 60°C — causing the plastic to expand, distort, and force the heavy glass sash downward against the bottom track. The result is one of the most common and misunderstood faults we encounter across the Rock: the dropped sash. A window that was effortless to operate six months ago now catches on the bottom frame, requires brute force to close, or simply refuses to lock at all.
Add to this the punishing Levanter wind humidity, airborne Mediterranean sea salt, and Calima dust abrasion, and Gibraltar’s standard factory-grade uPVC hardware — espagnolette locking gearboxes, friction hinges, perimeter rubber gaskets — faces a rate of degradation that no European manufacturer’s warranty period was ever designed to account for. Attempting to force a warped or dropped PVC sash shut using online tutorials designed for temperate UK climates routinely results in a snapped handle spindle or a shattered sealed unit — transforming a manageable hardware fault into an emergency window pane replacement.
At RHS Window Repair, we understand the specific physics of plastic frames in coastal Mediterranean heat. As the leading specialists in Expert Window Repair in Gibraltar, we carry the exact specialised tools and climate-specific components required to diagnose the root cause of every uPVC failure and restore the window to flawless factory condition permanently.

“Many homeowners assume that because their PVC window is catching on the bottom frame, the entire window needs to be ripped out and replaced. This is a costly myth pushed by installation salesmen. In 95% of cases, the intense Gibraltar heat has simply caused the sash to drop. By performing a professional toe-and-heeling procedure and replacing the internal espagnolette gearbox where necessary, we can restore the window to perfect working order for a fraction of the cost of a new frame.”

Data Insight: How Gibraltar’s Environment Attacks uPVC Profiles
The table below maps each of Gibraltar’s four primary environmental stressors directly to the uPVC hardware failure it causes and the precise RHS professional solution deployed to resolve it permanently.
Environmental Stressor
Impact on uPVC Hardware & Frames
The RHS Professional Solution
Intense UV Heat
Thermal expansion causes the plastic frame to warp, forcing the glass sash to drop and catch on the bottom lip.
Toe-and-Heeling: redistributing glass weight with precision glazing packers to lift the sash back into perfect square alignment.
Airborne Sea Salt
Corrodes internal steel espagnolette locking gearboxes, causing the handle to spin freely without engaging the lock.
De-glazing the frame and installing a brand-new corrosion-resistant multipoint locking mechanism and spindle assembly.
Levanter Wind Pressure
Blows out weakened perimeter rubber seals, causing persistent whistling draughts and complete loss of the thermal barrier.
Stripping out perished seals and fitting modern, UV-resistant EPDM memory-foam rubber gaskets rated for coastal conditions.
High Humidity
Degrades the hermetic perimeter seal of double-glazed units, causing internal condensation and permanent fogging between the panes.
Precise window pane replacement: installing a new argon-filled, Low-E sealed unit without removing the original uPVC frame.
By addressing each of these four environmental failure modes at component level — rather than selling you an unnecessary full frame replacement — our uPVC Window Repair in Gibraltar methodology extends the operational life of your frames by decades and protects your property investment against Gibraltar’s unique atmospheric chemistry.
Our Services
Comprehensive PVC Window Repair Services We Offer
We are not general handymen — we are dedicated uPVC architectural technicians. Our strict repair-first strategy targets the exact failing component, saving you thousands of pounds over unnecessary full-frame installations. Every repair is executed with precision tools, premium climate-specific parts, and a formal quality assurance sign-off before we leave your property.
A dropped sash is the single most common uPVC fault we encounter across Gibraltar’s residential and commercial properties — and the one most frequently misdiagnosed as a terminal frame failure by sales representatives who would prefer to sell you a new window. The reality is almost always far simpler. Gibraltar’s intense summer heat causes the uPVC frame to undergo repeated thermal expansion and contraction cycles that gradually displace the glazing packers supporting the glass sash from below. As these packers shift, the entire weight of the glass unit — which can exceed 30 kilograms in a large casement — migrates to the bottom corner of the frame, causing the sash to drop, twist, and catch against the bottom plastic lip.
Our solution is the professional toe-and-heeling procedure: we carefully remove the plastic glazing beads, extract the glass sash, and use a precision set of graduated plastic and composite glazing packers to re-brace the glass diagonally within the frame. This redistributes the weight load perfectly across all four sides of the uPVC frame, returns the sash to a perfect geometric square, and restores effortless operation. Where the thermal cycling has also damaged the friction hinges, we replace these simultaneously using climate-specific hardware sized to the exact uPVC profile in your building.
When your uPVC window handle rotates a full 360 degrees without engaging the locking bar, or when the window is permanently jammed in the closed position with no mechanism to release it, the internal espagnolette gearbox has failed. This is the metal heart of the multipoint locking system — the component that converts your handle rotation into the simultaneous upward and downward movement of the shoot-bolts that engage the keep-plates embedded in the surrounding frame.
In Gibraltar’s salt-laden coastal atmosphere, airborne sea salt crystals penetrate the narrow tolerance gaps between the gearbox casing and its internal drive components. Over time this causes electrochemical corrosion of the steel gears and drive plate, seizing the mechanism entirely. The user then applies increasing force to the handle — until the square metal spindle that drives the gearbox shears completely. Our technicians carry the full range of multipoint espagnolette gearboxes compatible with the European uPVC systems installed across Gibraltar, from Siegenia and Winkhaus to local fabricator profiles. We safely bypass the seized mechanism without damaging the plastic frame, replace the complete locking assembly, and restore every shoot-bolt engagement point to simultaneous, positive locking action.
3. Draught-Proofing & EPDM Rubber Gasket Renewal
If your uPVC windows whistle audibly during the Levanter easterly, if you feel cold or warm air passing through the frame on a still day, or if water has begun to appear on the interior sill following coastal rain storms, the EPDM rubber gaskets sealing your sash against the frame have reached the end of their service life. Gibraltar’s intense UV radiation degrades standard factory-fitted rubber at an accelerated rate: the elastomer chemistry oxidises, loses its memory, and permanently flattens within the uPVC channel — leaving the perimeter compression gap partially or fully open to the atmosphere.
Our draught-proofing renewal is a meticulous, full-perimeter process. We carefully strip all degraded rubber from the extruded uPVC channels — including the main compression gasket, the bubble gasket on the sash face, and the wiper seals on the opening sashes — and replace the entire perimeter with premium, UV-stabilised EPDM memory-foam acoustic gaskets rated specifically for high-UV, high-salt coastal environments. These hold their cross-sectional profile under sustained compression loading, rather than permanently deforming like standard rubber. The immediate results are measurable: zero draughts, significantly reduced exterior noise penetration, and your air conditioning remaining exactly where it belongs during Gibraltar’s intense summer months.
4. Specialised uPVC Window Pane Replacement
When a double-glazed unit within a uPVC frame develops the characteristic internal fogging between its two glass panes — the result of hermetic perimeter seal failure allowing moisture to enter and condense on the inner glass surfaces — no amount of cleaning will resolve it. The sealed unit is irreparably blown and must be replaced. Equally, impact damage that shatters a pane entirely requires immediate action to restore the security and weather-tightness of the opening.
Our specialist window pane replacement service removes only the failed glass unit — not the surrounding uPVC frame. We carefully extract the plastic glazing beads, remove the blown or damaged sealed unit from the rebate, and install a new high-efficiency, argon-filled, Low-E glass sealed unit manufactured to the micro-millimetre specifications of your existing frame. The critical final step is applying the toe-and-heeling packer arrangement to the new unit before re-fitting the glazing beads, ensuring the glass weight is optimally distributed and the new unit will not drop or contact the bottom track over its service life.

Residential and Commercial Properties
Whether you own a flat in the South District, a family home in Queensway Quay, or manage a portfolio of commercial storefronts across the Rock, faulty uPVC windows are a significant and growing liability — financially, legally, and in terms of daily comfort. As the leading choice for Expert Window Repair in Gibraltar, we tailor our service approach and response protocols to meet the distinct needs of residential and commercial property types.
Residential: Protecting Comfort & Lowering Energy Bills
For Gibraltar homeowners and tenants, your home is your sanctuary — and a broken uPVC window lock or a perished weather seal directly undermines both your family’s physical security and your property’s thermal performance simultaneously. During Gibraltar’s intense summer, a flattened door seal or a draught gap around a dropped sash bleeds the air conditioning you are paying for directly into the atmosphere. During the cold, damp Levanter winter, the same gap channels moisture-laden wind into every corner of the room.
Our professional uPVC repairs instantly restore both the thermal barrier and the physical security of your home — without the need for scaffolding, masonry work, or internal replastering. We fix the failing mechanics. You get your Mediterranean views back without the rattling frames, the whistling Levanter draughts, or the inflated utility bills.
Actionable Tip for Homeowners
Never force a uPVC handle if the window is stiff or catching on the frame. The internal cast-metal spindle will shear under pressure, converting a simple glazing adjustment into a full gearbox replacement. If your window is difficult to operate, contact a professional immediately to adjust the friction hinges and re-toe-and-heel the glazing unit before any further force is applied.

24 / 7Emergency response availability across Gibraltar
Property managers, estate agents, and commercial landlords in Gibraltar operate under strict compliance, health, and safety obligations that individual homeowners simply do not face. You cannot afford to rely on DIY fixes or delay your response to tenant complaints regarding faulty locks or draughty windows. Under standard Gibraltar tenancy agreements, structural and exterior window hardware — including locking mechanisms, friction hinges, and sealed glazing units — is the landlord’s direct legal responsibility. A broken window is simultaneously a physical security liability, a potential Building Control breach, and in many cases a direct violation of the tenant lease agreement.
RHS Window Repair acts as your dedicated maintenance arm when tenant complaints arise. We attend within agreed SLA timeframes, liaise directly with tenants on your behalf, execute emergency boarding where immediate security is required, and provide fully documented, itemised condition reports and compliance certificates with every completed job. Our 24/7 commercial B2B maintenance contracts mean you never need to scramble for a reliable, insured contractor at short notice again — and you have the paper trail to protect your position should a complaint reach Gibraltar’s housing authorities.

Specialist On-Site Assessment
Our certified, uniformed technicians arrive driving fully stocked mobile inventory vans. We accurately measure your specific uPVC frame profile — using digital calipers to capture exact rebate depths, sash dimensions, and locking bar throw lengths — ensuring a perfect fit for every replacement hinge, gearbox, and sealed glass unit we install. Because uPVC systems vary significantly between manufacturers such as Rehau, Schüco, and Eurocell, our deep technical knowledge ensures we match the exact architectural specification of your building.
03
Precision Repair & Alignment Testing
We install the new components, perform the toe-and-heeling alignment procedure where required, and conduct a strict weather-seal and compression test across every closing point on the perimeter. We check for acoustic leakage using a paper-strip compression test, verify handle tension and spindle engagement, and confirm every multipoint shoot-bolt locks simultaneously before we sign off the job. We guarantee the window operates exactly as it did when it was factory-fresh — or we return until it does.

Frequently Asked Questions
Frequently Asked Questions
When it comes to PVC / uPVC Window Repair in Gibraltar, property owners are frequently misled by generic overseas advice that does not account for our unique coastal environment. Here are the expert answers you need to protect your property and your budget.
My uPVC window is catching on the bottom frame and is hard to close. Can you fix it without replacing the whole window?
Yes — and in the vast majority of Gibraltar cases, this requires no frame replacement whatsoever. This is a classic dropped sash, caused by Gibraltar’s intense heat displacing the glazing packers that support the glass weight inside the uPVC frame. We fix it by performing a professional toe-and-heeling procedure: carefully removing the glass unit, repositioning the glazing packers to redistribute the weight diagonally across all four sides of the frame, and adjusting the friction hinges to the correct tension. The window then glides perfectly again without any modification to the original uPVC frame.
The handle on my uPVC window just spins freely and it won’t lock. Do I need a new window?
No — you do not need a new window. A handle that spins a full 360 degrees without engaging the locking bar almost always means the internal espagnolette gearbox has failed: its steel drive components have either corroded from salt ingress or the spindle has sheared under load. Our 24/7 technicians safely open the jammed frame without damaging the plastic profile, replace the complete internal locking gearbox assembly on the spot, and restore full multipoint locking action immediately.
Why are my PVC windows letting in draughts during the Levanter wind?
The combination of Gibraltar’s intense UV radiation and constant Levanter wind exposure dries out the EPDM rubber weather seals around your uPVC windows at a rate far exceeding what any European manufacturer’s specification anticipated. Once these seals flatten and crack in the uPVC channel, the sash can no longer compress them effectively when closed — leaving a continuous draught gap around the entire perimeter. We strip out all degraded rubber and install premium UV-stabilised EPDM memory-foam replacement gaskets that hold their shape under sustained compression, permanently eliminating the draughts.
Is it really cheaper to repair my uPVC window instead of replacing the entire frame?
In the vast majority of cases, yes — significantly so. Most uPVC window faults are a failed locking gearbox, a dropped glazing packer arrangement, or a perished rubber gasket: individual components that cost between £50 and £200 to replace professionally. A full uPVC frame replacement in Gibraltar, by contrast, requires a bespoke manufactured frame, scaffolding or access equipment, local permits, debris removal, and internal wall reinstatement — regularly totalling £800 to £1,500 per window or more. Our repair-first approach delivers equivalent long-term performance in one to two hours with zero structural disruption.
Do you replace the glass if my uPVC window is foggy inside between the panes?
Yes. Internal fogging between the glass panes is caused by hermetic seal failure — moisture has entered the argon cavity and the sealed unit is permanently blown. No amount of cleaning or drying will resolve it. We carry out a precise window pane replacement: removing the plastic glazing beads, extracting the blown sealed unit from the uPVC rebate, and installing a new high-efficiency, argon-filled Low-E sealed glass unit sized exactly to your frame. Your original uPVC frame remains completely intact throughout.

Most uPVC window faults are a failed locking gearbox, a dropped glazing packer arrangement, or a perished rubber gasket: individual components that cost between £50 and £200 to replace professionally. A full uPVC frame replacement in Gibraltar, by contrast, requires a bespoke manufactured frame, scaffolding or access equipment, local permits, debris removal, and internal wall reinstatement — regularly totalling £800 to £1,500 per window or more. Our repair-first approach delivers equivalent long-term performance in one to two hours with zero structural disruption.
Do you replace the glass if my uPVC window is foggy inside between the panes?
Yes. Internal fogging between the glass panes is caused by hermetic seal failure — moisture has entered the argon cavity and the sealed unit is permanently blown. No amount of cleaning or drying will resolve it. We carry out a precise window pane replacement: removing the plastic glazing beads, extracting the blown sealed unit from the uPVC rebate, and installing a new high-efficiency, argon-filled Low-E sealed glass unit sized exactly to your frame. Your original uPVC frame remains completely intact throughout.
