Repair or replace: which is better?
Replacing the frame or sill costs far more, and new uPVC may not match the weathered frames around it. Repairing the damage leaves the unit in place. Repairs from £95, with every job priced individually. A few things move the price: access, material, the extent of the damage and whether we can do several items together. Send pictures and you’ll get a fixed figure.
What you get with us
- Dust sheets down, tidy finish
- Colour-matched on site

Advice
Maentwrog questions
Can I get a quote without a visit?
Nearly always. If pictures don’t show enough, we will ask for another angle.
Will there be a smell?
Expect a mild smell while we’re working, which fades afterwards.
Do you repair coloured uPVC?
Yes. We recreate the colour and grain by hand.
How do I book?
A close-up, a wider photo and your postcode. Then we’ll agree a date.
Do you charge for travel?
We don’t add a call-out fee. Your fixed price includes everything.
Can you repair something that is been repaired before?
In most cases. We remove the old repair before doing a new one.
Do you work in Maentwrog?
Yes. We work across the UK and travel to Maentwrog. Send pictures and we will quote, or call 0345 017 0787.
Will it make a mess?
We protect the room with dust sheets and masking first, and tidy up before we leave.
Work for landlords and builders
Builders, developers and site managers book us for snagging repairs, putting right damage done during fitting so nothing needs replacing. We’re CHAS, Constructionline and SafeContractor accredited.
We regularly price jobs from inventory or check-out photos. That means we can quote before you even visit the property, and we can arrange access with the tenant directly if that helps.
Prices and what affects them
Prices start from £95. We don’t charge extra for travel to Maentwrog. The price comes down to:
- Whether it’s a chip, crack, burn or wear
- The material
- The colour and finish to match
- How many items we do on one visit
Most people are surprised how affordable a repair is, especially compared with replacing and refitting. Send photos and we will give you the exact figure.
Send photos for a quote
Before you send photos, these tips help us give you a firm price:
- A clear, close picture of the problem area
- A picture taken from further back
- Good light, ideally daylight, without flash glare
- Where you are, by postcode
Email us pictures of the damage and a wider shot of the whole item, with your LL41 postcode, and we’ll come back with a fixed quote.
DIY repairs versus a professional job
You can buy a DIY kit for most repairs, and they can make a small mark look better. The trouble is colour and preparation: they come in a handful of shades, and if the surface isn’t prepared the repair won’t last.
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. It does add a little time, so tell us about it when you send pictures.
