Prices and what affects them
Prices start from £95. We don’t charge extra for travel to Sling. The price comes down to:
- Previous DIY repairs that have to come out
- How many areas need work
- What the surface is made of
- How easy the damage is to reach
Every job is a little different, so we price each one individually. The size and type of damage, the material and access all make a difference, and doing several things on one visit costs less than separate visits.
Getting a price from pictures
Almost every job we do is priced from pictures. This is what we need:
- Something in shot to show the size
- Good light, ideally daylight, without flash glare
- Details of any past repairs
- What it’s made of, if you know
Getting a quote takes a couple of minutes: photograph the damage, then the entire window, door or sill, include your postcode and send them over. You’ll get a fixed price, not an estimate.
About our uPVC repair in Sling
The damage is filled and refinished so it blends into the frame, woodgrain finishes included. Builders and developers use us for snagging repairs too. If you are dealing with chips and dents and burns on sills, we can help, on window frames & sills, coloured and woodgrain uPVC and white uPVC alike.
A one-year guarantee comes with the work, just as it does everywhere we cover. Clean with warm soapy water and a soft cloth. Don’t use solvents or scourers.

When a repair is not the answer
We would rather lose a job than do one that won’t last, so these are the limits:
- Failed or misted double glazing units
- Broken locks, hinges or mechanisms
- Frames that are warped or out of square
Send us photos and we’ll tell you honestly.

Repair or replace: which is better?
A new window, door or sill is a much bigger job, and it may not match the rest after years of weathering. A repair keeps the original. Repairs from £95, with every job priced individually. Compared with replacing, repairing normally costs far less, because there’s no removal, plumbing or making good. Your fixed quote shows exactly what’s included.

Questions from Sling
Do I have to be there?
Yes. The technician needs access to the room for the visit, at a time that suits you.
Is a repair better than a new one?
In most cases, yes. A repair skips the removal, fitting and redecorating. We will be honest if it’s not worth it.
Can you match woodgrain uPVC?
Yes. We recreate the colour and grain by hand.
Is there any odour?
Expect a mild smell while we are working.
Can you quote from pictures?
Typically, yes. Clear pictures let us give you a fixed price without visiting.
How soon can you come?
We will give you dates with your quote. If it’s urgent, say so and we’ll do what we can.
Do you hold any accreditations?
Yes. Our accreditations include CHAS, Constructionline and SafeContractor. The full list is on our accreditations page.
Can tenants book a repair?
We can work for tenants, landlords or agents. Get your landlord’s agreement first.
Do you need uPVC repair in Sling?
uPVC is hard-wearing, but it does get damaged: ladders, tools and building work scratch and chip it, candles and cigarettes burn sills, and removed fittings leave holes.
Customers normally contact us about:
- Holes from removed fittings and alarms
- Burns on sills
- Damage during building work
- Chips and dents
Before you book anyone
- Whether there are any call-out or travel charges
- How the colour is matched
- What aftercare is recommended
- How long it needs to cure

Can I fix it myself?
For a hairline mark somewhere you will never see, a kit may be enough. For anything you look at every day, anything that has rusted, cracked or holed, or anything on a coloured surface, it’s worth having it done properly.
If you do try a kit, read the instructions carefully and work on a clean, dry surface, and don’t use it until it has fully cured. If it doesn’t work out, we can still repair it properly.
The process
Once we are through the door, the aim is to do the job without disturbing the rest of your home. We mask off everything nearby, the work takes a morning or an afternoon, depending on what we find, and we finish by cleaning up and talking you through the result.
- First the frame or panel is cleaned.
- Scratches, chips and holes are filled.
- The repair is sanded smooth.
- The finish is colour matched, woodgrain included.
- The repair is blended into the surface around it.
Preparing for the visit
- Mention any earlier repairs or resurfacing
- Let the surface dry out before the visit
- Keep children and pets away from the room on the day
How to get a price
The quickest way to a price is to send a couple of photos using our quote form or ring us. We will say immediately if a repair is the right fix.
