Window Draught Proofing and Alignment
If your uPVC windows are letting in cold air or rattling in the wind, professional window draught proofing and alignment can restore a snug seal and smooth operation. At Window Repairs Sutton, we specialise in uPVC window repairs for local homes, focusing on adjustments and seals to reduce draughts without full replacement. Our 10+ years of experience and public liability insurance ensure reliable service from DBS-checked technicians.
Who This Is For
This service suits homeowners in Sutton noticing unwanted breezes around their double-glazed windows, even when closed. It’s ideal if your windows feel loose, make noise, or fail to compress properly against the frame. We help those seeking cost-effective fixes for everyday wear rather than major overhauls.
Common signs include higher energy bills from escaping warmth or discomfort near window seats. If you’ve tried DIY tape but the problem persists, our targeted approach addresses the root issue.
Common Causes
Draughts and rattles often stem from gradual wear in uPVC mechanisms. Over time, hinges sag, seals degrade, or frames shift slightly due to building movement or thermal expansion.
Key culprits include:
- Worn compression seals that no longer expand to fill gaps.
- Misaligned windows from loose toe and heel adjustments.
- Stiff or bent friction stays preventing proper closure.
- Perimeter weatherseals cracked by weather exposure.

Likely Fixes & Options
We start with a thorough on-site inspection to pinpoint the issue, then recommend tailored solutions. Most jobs involve non-invasive adjustments or part swaps, completed efficiently.
Options typically include:
- Window adjustment: Fine-tuning window alignment and adjustment via screws on hinges for better closure.
- Draught proofing: Replacing draught excluders or window sealing strips around edges.
- Window mechanism repair: Lubricating or realigning stays and handles for rattle-free operation.
- Full seal overhaul: Installing new compression seal kits if multiple areas are affected.
These restore insulation without disrupting your home. We explain each step upfront, focusing on double glazing repairs that match your window’s age and type.
How We Identify The Right Parts
Diagnosis begins with close examination of your window’s profile, hinges, and seals. Our technicians measure gaps, test compression, and note any asymmetry using specialist tools.
We take photos and reference manufacturer codes etched on frames to match OEM-spec parts. This ensures compatibility and avoids guesswork. Local stock and quick supplier links mean minimal delays.
Parts & Compatibility
uPVC windows from major brands like Rehau, Veka, or Kommerling use standard seal profiles, but sizes vary by era and model. We stock common draught excluders and weatherseals for casement and tilt-before-turn designs.
- Fin seals: Thin, flexible strips for inner edges; easy retrofit.
- Knife-edge seals: Robust for outer frames; UV-resistant.
- P-profile seals: Bulb-shaped for high compression.
Check our draught excluders and weatherseals page for visuals and stock details. We confirm fit before ordering, excluding non-uPVC types like sash or wooden frames.
Pricing Guide
Costs depend on window count, access, and parts needed—transparent from the start. A basic window alignment starts around £80-£120 per window, while full draught proofing with seals averages £120-£200.
Factors influencing price:
- Number of seals replaced (e.g., top, bottom, sides).
- Hinge adjustments vs. full mechanism work.
- Multi-window discounts for bulk jobs.

FAQs
How long does window draught proofing take?
Most alignments and seal swaps finish in 1-2 hours per window, weather permitting. Complex multi-window jobs may span a day.
Will this fix rattles as well as draughts?
Yes, window alignment often resolves both by ensuring even pressure. We test post-repair for silence and seal.
Do you handle tilt and turn windows?
No, we exclude tilt and turn, sliding, sash, or inward-opening types—see our services list. Focus remains on standard uPVC casements.
Can I do window adjustment myself?
DIY tweaks risk worsening alignment. Professional tools and knowledge prevent damage.
What’s the warranty on parts?
New seals come with manufacturer backing; labour covered by our workmanship assurance.
When Repair May Not Be Suitable
Sometimes, draught proofing and alignment isn’t viable. Severe frame warping, rot, or 25+ year-old windows may need replacement for lasting results.
Repair fails if:
- Structural issues like subsidence affect the frame.
- Seals unavailable for obsolete profiles.
- Windows are excluded types: sash, sliding, wooden, or tilt and turn.
In these cases, we advise honestly—repair could be short-term. Better insulation comes from new units.
