Gallt-y-foel questions
Do I need to be at home?
Yes. The technician needs access to the room for the visit, at a time we agree with you.
Will it make a mess?
We protect the room with dust sheets and masking first, and we clean up when we have finished.
Is the work guaranteed?
Yes, for a year. If anything goes wrong with the repair within the year, we return to fix it.
Is there a call-out fee?
There is no separate call-out charge. The fixed quote covers the visit and the work.
Can you redo someone else’s repair?
Yes, regularly. Removing the old work can add time, and that is in the quote.
Can you do more than one item on the same visit?
Yes. Doing several items on one visit generally costs less than separate visits. Send pictures of everything you’d like done.
What does uPVC repair cost?
Repairs from £95. The exact price depends on the damage, so we quote from photos. You know the full cost before anything is booked.
Do you do work for letting agents?
Yes, often. We can quote for several properties together and work between tenancies.
Landlords, agents and businesses in Gallt-y-foel
Builders, developers and site managers book us for snagging repairs, putting right damage done during fitting. We hold CHAS, Constructionline and SafeContractor accreditations.
We carry out planned and one-off repairs for housing associations and facilities teams in Gwynedd and across the UK. Repairing in place avoids the disruption of a replacement, which matters when someone is living in the home.
Repair or replace: which is better?
A new window, door or sill costs far more, and new uPVC may not match the weathered frames around it. A repair keeps the original. Repairs from £95, with every job priced individually. Every job is a little different, so we price each one individually. What’s damaged, how badly and how easy it is to reach all play a part, and doing several things on one visit costs less than separate visits.

Prices and what affects them
Prices start from £95. Quotes are free and the price is fixed. What we take into account:
- The colour and finish to match
- How many areas need work
- Whether it’s a chip, crack, burn or wear
- The material and finish
There are no surprise extras on the day. The price we quote from your pictures is the price you pay, and if the damage turns out to be different, we discuss it before starting.
Send photos for a quote
Good photos mean an accurate price. Here’s what we find most useful:
- One picture of the entire window, door or sill
- Good light, ideally daylight, without flash glare
- Any earlier repairs or coatings
- The postcode, so we can plan the visit
If you’re in Gallt-y-foel and want a price, the easiest route is photos: one close up, one from further back, plus your postcode. We reply with a fixed quote and our next available dates.
When to call us in Gallt-y-foel
uPVC is tough but not indestructible: ladders and building work leave scratches and chips, candles and cigarettes burn sills, and old fittings leave holes.
Send us a picture if you notice any of these:
- Burns on sills
- Holes from removed fittings and alarms
- Scratches from ladders and furniture
- Chips and dents
Comparing quotes
- A fixed price, and whether VAT is included
- What happens if they find more damage
- What prep work is covered
- How long it needs to cure
Can I fix it myself?
A DIY attempt isn’t a disaster. We remove the old filler and start again, so it will not stop us repairing it. Just mention it when you send pictures, as it can add time.
A kit can be fine for a tiny mark out of sight. For damage in plain view, cracks, holes or rust, or coloured finishes, a professional repair is worth it.
What we can’t put right
A repair isn’t right for every job, for example:
- Failed or misted double glazing units
- Broken locks, hinges or mechanisms
- Frames that are warped or out of square
Not sure? Send pictures and we will give you a straight answer.
