DIY repairs versus a professional job
You can buy a DIY kit for most repairs, and they can make a small mark look better. 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.
The difference between a kit and a professional repair is mostly in the preparation and colour. 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.
uPVC repair in Cranford St John without replacing anything
We fill and refinish the damage to match the frame, including woodgrain finishes. Builders and developers use us for snagging repairs too. We’re frequently asked to fix burns on sills and damage during building work, across coloured and woodgrain uPVC, doors & door panels and white uPVC.
All of our repairs are guaranteed for twelve months. We return to put right any problem with the work. Warm soapy water and a soft cloth are all it needs. Avoid solvents and abrasive cleaners.

What else we do in Cranford St John
How we price uPVC repair
Prices start from £95. There are no hourly rates or hidden extras. The price is based on:
- The type of damage
- Whether we combine several jobs
- What the surface is made of
- How much damage there is
We do not add extras on the day. The price we quote from your photos is the price you pay, and if the damage turns out to be different, we discuss it before starting.
How to get a fixed price
It only takes a minute to photograph the damage. Please include:
- Any earlier repairs or coatings
- A picture taken from further back
- Good light, ideally daylight, without flash glare
- Any details about the material
Ring 0345 017 0787, or send us photos through the quote form. With one close-up and one wider picture, we can give you a fixed price.
When to call us in Cranford St John
uPVC is tough but not indestructible: ladders and building work leave scratches and chips, candles and cigarettes mark sills, and removed fittings leave holes.
Look out for these signs:
- Damage during building work
- Scratches from ladders and furniture
- Burns on sills
- Holes from removed fittings and alarms
Questions to ask before booking
- What aftercare is recommended
- Whether they match the colour on site
- What the guarantee covers, and for how long
- How long it needs to cure
When a repair isn’t the answer
To be straight with you, some problems need a different fix:
- 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’ll give you a straight answer.
Surfaces we repair
- Conservatory frames
- Coloured and woodgrain uPVC
- Window frames & sills
- Doors & door panels
- White uPVC
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 leaves the unit in place. Our uPVC repair starts from £95. The price reflects the work involved, not where you live. You’ll see the full price before booking.

For landlords and businesses
For developers and builders, we fix damage before handover. We can visit several plots in one trip.
Letting agents frequently send us pictures straight from the inventory. That means we can quote before you even visit the property, and we liaise with tenants about access if you’d like us to.
The process
We agree an arrival time beforehand, so you are not left guessing. Once we’re there, the work takes a few hours in most cases. We leave the room clean and ready to use once it has cured.
- We clean the frame or panel.
- Next we fill the damage.
- We sand the repair smooth.
- We colour-match the finish, including woodgrain effects.
- Finally we blend it into the rest of the frame.
Before we arrive
- Have somewhere for us to park nearby if possible
- Mention any earlier repairs or resurfacing
- Mention if the room is upstairs or in a flat
How to get a price
Getting a quote takes a couple of minutes: take one close-up and one wider shot of the window, door or sill, add your postcode and send them over. What comes back is a fixed price, not a guess.

Cranford St John questions
Is repairing better than replacing?
Generally, if the item is otherwise sound. Repairing avoids the cost and disruption of replacing. If replacing would be better, we will say so.
Is it OK to have pets in the house?
We ask you to keep children and pets out of the room while we work. The rest of the house is unaffected.
Do you cover the whole of Northamptonshire?
The entire UK, including all of Northamptonshire. Send your postcode with your photos and we will confirm dates.
What happens after I send photos?
We come back with a fixed price. You’re under no obligation.
Can I add another job to the visit?
Yes, and it’s often cheaper. Just add the extra items to your pictures and you’ll get one combined price.
Do you work for landlords and businesses?
Yes, frequently. We quote for multiple addresses and fit around tenancy changeovers.
Can I get a quote without a visit?
In nearly every case. If pictures don’t show enough, we’ll ask for another angle.
What if the damage is worse than the pictures show?
It’s rare, but if it happens we talk to you first. You decide whether to go ahead.
