DIY repairs versus a professional job
A DIY attempt is not a disaster. We take the old repair out and do it properly, so it won’t stop us repairing it. Just mention it when you send pictures, as it can add time.
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 often lifts.
Do you need uPVC repair in Pen-sarn?
uPVC is tough but not indestructible: ladders and building work leave scratches and chips, candles and cigarettes burn sills, and old fittings leave holes.
It’s worth getting a quote if you see:
- Scratches from ladders and furniture
- Holes from removed fittings and alarms
- Chips and dents
- Burns on sills
What to look for in a quote
- What protection goes down before work starts
- Whether the price covers travel
- Whether the colour is mixed to match
- How long the guarantee is and what it covers
Your questions about uPVC repair in Pen-sarn
It’s been repaired before. Can you still fix it?
Most of the time. Tell us what was done before and we’ll plan for it.
What does uPVC repair cost?
Repairs from £95. We give a fixed price from your pictures. Send a close-up of the damage and a wider photo with your LL45 postcode.
Do you work in Pen-sarn?
Yes. We work across the UK and travel to Pen-sarn and the rest of Gwynedd. Send us pictures for a fixed quote, or call 0345 017 0787.
Can you repair several things at once?
Yes, and it’s often cheaper. Send pictures of everything together and we will quote them together.
How do I book?
Photos of the damage, a photo of the entire window, door or sill and your postcode. Then we will agree a date.
Can you repair a burn on a uPVC sill?
Yes. The burn is filled and refinished to match.
What if the damage is worse than the photos show?
It’s rare, but if it happens we talk to you first. You decide whether to go ahead.
Can you quote from photos?
Nearly always. We only ask to see it in person if the pictures cannot show what we need.
Landlord and trade work in Pen-sarn
For developers and builders, we fix damage before handover. We can visit several plots in one trip to keep costs down.
Letting agents often send us pictures straight from the inventory. You can have a price before you arrange access, and we can arrange access with the tenant directly if that helps.
What uPVC repair costs
Repairs from £95. There is no charge for travel to Pen-sarn. The price comes down to:
- What kind of damage it is
- Access to the area
- The material and finish
- How much damage there is
No two jobs are quite the same, so we price each one individually. The size and type of damage, the material and access all play a part, and combining jobs on one visit brings the cost down.
How to get a fixed price
You can generally get a fixed quote without us visiting. To help us price it:
- Any earlier repairs or coatings
- A clear, close picture of the problem area
- The material, if you know it
- A wider photo showing the whole window, door or sill
No survey visit is needed: we price from photos. Send them through the quote form, or call 0345 017 0787 if you’d rather talk it through, and we will come back with a fixed figure.
Repair or replace in Pen-sarn?
A new window, door or sill costs far more, and it may not match the rest after years of weathering. Repairing the damage leaves the unit in place. Repairs from £95, with every job priced individually. It helps to know what pushes a price up or down: the amount of damage, the material, access to the area, and how many jobs we do in one trip. Send photos and you’ll get a fixed figure.
Why us?
- One visit for most repairs
- We’ll tell you if it’s not worth repairing
- Colours mixed by hand to suit your surface
