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. A repair leaves the unit in place. Prices start from £95. What it costs depends on how much damage there is and what kind, what it’s made of and how many items we do on one visit. We give a fixed price from your photos, so you know the cost before you book.

How we price uPVC repair
Prices start from £95. A fixed quote means you know the cost before booking. We take into account:
- Doing more than one item at once
- Unusual colours or finishes
- The material and finish
- How much damage there is
There are no surprise extras on the day. The price we quote from your photos is the price you pay, unless the damage turns out to be different, in which case we talk to you first.
How to get a fixed quote
It only takes a minute to photograph the damage, and it saves a visit. Please include:
- A close-up of the damage, in focus
- Where you are, by postcode
- Details of any past repairs
- Something in shot to show the size
We price from pictures so you don’t have to wait in for a survey. Send them through the quote form, or call 0345 017 0787 if you’d rather talk it through.

When to call us in Mona
uPVC is tough but not indestructible: ladders, tools and building work scratch and chip it, candles and cigarettes burn sills, and old fittings leave holes.
Typical reasons for a call-out include:
- Damage during building work
- Holes from removed fittings and alarms
- Chips and dents
- Scratches from ladders and furniture
Questions to ask before booking
- What preparation is included
- Whether there are any call-out or travel charges
- Whether the colour is mixed to match
- Whether the price is fixed and includes VAT
Work for landlords and builders
Housing associations and facilities teams use us for planned and reactive repairs in Isle of Anglesey and across the UK. Repairing in place avoids the disruption of a replacement, which matters when someone is living in the home.
Rented homes see more wear and tear, and replacing items every time a tenant leaves is expensive. A repair between tenancies is a cheaper way to keep the property in good order.

Yes. We work for landlords, agents, builders and businesses as well as homeowners in Mona.
Can tenants book a repair?
Of course. Check with your landlord; we can send the quote to them too.
Is it worth repairing rather than replacing?
Usually, if the item is otherwise sound. Repairing avoids the cost and disruption of replacing. If replacing would be better, we’ll say so.
What we can’t put right
A few problems are outside what a surface repair can do:
- Failed or misted double glazing units
- Broken locks, hinges or mechanisms
- Frames that are warped or out of square
Not sure? Send photos and we will give you a straight answer.
Surfaces we repair
- Conservatory frames
- Window frames & sills
- Doors & door panels
- Coloured and woodgrain uPVC
- White uPVC
Can I fix it myself?
A DIY attempt isn’t a disaster. We take the old repair out and do it properly, so it will not stop us repairing it. Just mention it when you send photos, as it can add time.
What a professional repair adds is preparation, colour matching and finishing. We clean and key the area properly, mix the colour to your surface and finish it to the same sheen, then guarantee it for a year.
