Repairing versus replacing in Grendon
A new window, door or sill is a much bigger job, and new uPVC may not match the weathered frames around it. A repair keeps the original. Prices start from £95. Every job is a little different, so each one is priced on its own. The size and type of damage, the material and access all make a difference, and combining jobs on one visit brings the cost down.

When a repair is not the answer

What we’re called out for in Grendon
uPVC is tough but not indestructible: ladders and building work leave scratches and chips, candles and cigarettes mark sills, and removed fittings leave holes.
These are the problems we’re asked about most:
- Holes from removed fittings and alarms
- Scratches from ladders and furniture
- Chips and dents
- Damage during building work

DIY repairs versus a professional job
We understand the appeal of fixing it yourself. The risk is that a kit repair hides the damage for a while, then fails, and the old filler has to come out before a proper repair.
For a hairline mark somewhere you will never see, a kit may be enough. For damage in plain view, cracks, holes or rust, or coloured finishes, it’s worth having it done properly.

Questions from Grendon
Can a burnt window sill be fixed?
Yes. We fill and refinish the burnt area to match.
What does uPVC repair cost?
Prices start from £95. The exact price depends on the damage, so we quote from photos. You know the full cost before anything is booked.
Is a repair better than a new one?
Typically, if the item is otherwise sound. A repair avoids removal and making good. We will tell you honestly if replacement makes more sense.
Do you cover Grendon?
Yes, we do. We send a technician to Grendon for every job, with no extra charge for travel.
Is it messy?
Very little mess: we sheet and mask everything nearby, and we leave the room clean.
Can you price it without visiting?
Usually, yes. A close-up and a wider photo are enough to give a fixed price.
Can you do more than one item on the same visit?
Yes, and it’s frequently cheaper. Just add the extra items to your photos and you will get one combined price.
What happens after I send photos?
We come back with a fixed quote, plus dates. You are under no obligation.
Landlord and trade work in Grendon
Builders, developers and site managers book us for snagging repairs, fixing chips and scratches before handover so nothing needs replacing. We are CHAS, Constructionline and SafeContractor accredited.
Builders use us to fix snagging damage before handover, saving last-minute replacements. We can visit several plots in one trip to keep costs down.
What uPVC repair costs
Prices start from £95. Each job gets its own fixed price. These are the things that affect it:
- Previous DIY repairs that have to come out
- How many items we do on one visit
- Access to the area
- The colour and finish to match
Instead of hourly rates, we price the entire job up front. Damage, material and access decide it, and combining items on one visit brings it down.
How to get a fixed price
Almost every job we do is priced from pictures. This is what we need:
- Natural light rather than flash
- Whether it’s been repaired or coated before
- Any details about the material
- Where you are, by postcode
Upload a picture of the damage and a wider shot of the entire item, and tell us you are in Grendon, and we’ll reply with a fixed price.
