How we handle uPVC repair in Philadelphia
The damage is filled and refinished so it blends into the frame, woodgrain finishes included. We also do snagging repairs for builders. We’re often asked to fix holes from removed fittings and alarms and damage during building work, across white uPVC, window frames & sills and coloured and woodgrain uPVC.
Your repair is guaranteed for a year, as with every job we do. Warm soapy water and a soft cloth are all it needs. Avoid solvents and abrasive cleaners.

FAQs for Philadelphia
Will you leave a mess?
No. The work area is masked and covered, and we leave the room clean.
What do you need from me?
Just photos, your postcode and a contact number. On the day, access to the room.
What happens next?
You’ll get a fixed quote back, usually with dates to choose from. You’re under no obligation.
Do you come to Philadelphia?
Yes. We work across the UK and come to Philadelphia and the rest of Sunderland. Send us photos for a fixed quote, or call 0345 017 0787.
Is there any odour?
Expect a mild smell while we are working that clears as it cures.
I rent my home. Can I book you?
We’re happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
Do you repair coloured uPVC?
Yes. We recreate the colour and grain by hand.
Do you do work for letting agents?
Yes. We work for landlords, agents, builders and businesses as well as homeowners.
Do you need uPVC repair in Philadelphia?
uPVC is tough but not indestructible: ladders, tools and building work scratch and chip it, candles and cigarettes mark sills, and old fittings leave holes.
Look out for these signs:
- Chips and dents
- Scratches from ladders and furniture
- Holes from removed fittings and alarms
- Burns on sills
Questions to ask before booking
- When it can be used again
- Whether they match the colour on site
- The length of the guarantee and what it covers
- What aftercare is recommended
Should I try a DIY kit first?
A kit can be fine for a tiny mark out of sight. For damage in plain view, cracks, holes or rust, or coloured finishes, it’s worth having it done properly.
You can buy a DIY kit for most repairs, and they can tidy up a tiny mark. Where they fall down is colour and preparation: kits come in a few standard shades, and without proper cleaning and keying the filler frequently lifts.

Why repair rather than replace?
Replacing the frame or sill is a much bigger job, and it may not match the rest after years of weathering. Repairing the damage leaves the unit in place. Our uPVC repair starts from £95. Our prices are the same across the UK, with no extra for Philadelphia. The job itself decides the price: the material, the amount of damage and how many items.

Landlord and trade work in Philadelphia
Rental properties take more wear, and replacing things at every changeover adds up. Repairing between tenants keeps the property presentable for less.
Letting agents often send us photos straight from the inventory. That means we can quote before you even visit the property, and we can arrange access with the tenant directly if that helps.
What affects the price in Philadelphia
Repairs from £95. We charge the same across the UK, including Philadelphia. The price reflects:
- Doing more than one item at once
- Whether old repairs or coatings need taking off
- Where the damage is and how we get to it
- The material
A few things move the price: access, material, the extent of the damage and whether we can do several items together. Photos let us give you a fixed figure.
Getting a price from pictures
You can take the pictures on your phone. Just make sure we can see:
- Natural light rather than flash
- Whether it’s been repaired or coated before
- A photo taken from further back
- What it’s made of, if you know
Call 0345 017 0787 or use the quote form. With one close-up and one wider picture, we can price the job.
