How we price uPVC repair

Repairs from £95. We give every job a fixed quote from photos. This is what makes a difference:

  • The type of damage
  • Where the damage is and how we get to it
  • The size and number of damaged areas
  • How many items we do on one visit

No two jobs are quite the same, so each one is priced on its own. 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.

Quotes from your pictures

You can take the photos on your phone. Just ensure we can see:

  • A wider photo showing the entire window, door or sill
  • One sharp close-up of the damage
  • Daylight if possible, and no flash reflection
  • Something in shot to show the size

Upload a picture of the damage and a wider shot of the whole item, with your DA1 postcode, and we’ll come back with a fixed quote.

Can I fix it myself?

A DIY attempt isn’t a disaster. We take the old repair out and do it properly, so it doesn’t stop a professional repair. It does add a little time, so tell us about it when you send photos.

A kit can be fine for a tiny mark out of sight. For damage in plain view, cracks, holes or rust, or coloured finishes, it’s worth having it done properly.

For landlords and businesses

Builders, developers and site managers book us for snagging repairs, putting right damage done during fitting so nothing needs replacing. We hold CHAS, Constructionline and SafeContractor accreditations.

For developers and builders, we fix damage before handover, so there is no need to replace a damaged item at the last minute. Several plots can be done in one visit to keep costs down.

When to call us in Dartford

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.

You may need us if you’ve spotted:

  • Holes from removed fittings and alarms
  • Chips and dents
  • Scratches from ladders and furniture
  • Burns on sills

What to look for in a quote

  • The length of the guarantee and what it covers
  • A fixed quote, and whether VAT is included
  • How to care for the finish
  • Whether they match the colour on site

How to compare quotes

When we would advise against a repair

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 pictures and we’ll tell you honestly.

Materials we work on in Dartford

  • Coloured and woodgrain uPVC
  • Doors & door panels
  • Conservatory frames
  • Window frames & sills
  • White uPVC

Repairing versus replacing in Dartford

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. Prices start from £95. The price depends on how much damage there is and what kind, the material and how many jobs we combine into one visit. We give a fixed quote from your pictures, so there are no surprises on the day.

Why Dartford customers choose us

  • Colours mixed by hand to suit your surface
  • Fixed prices from your photos
  • Honest advice, even when it means no job
  • Everything repaired in place

How the visit works

When we visit, the technician arrives at the agreed time, protects the room with dust sheets and masking and gets started. Expect it to take a morning or an afternoon. We clean up when we’re done and tell you when it’s ready to use.

  1. We clean the frame or panel.
  2. Next we fill the damage.
  3. We smooth the repair.
  4. We colour-match the finish, including woodgrain effects.
  5. Finally we blend it into the rest of the frame.

Before we arrive

  • Plan for the room to be out of bounds to pets and children
  • Open a window if you can
  • Let us know if it has been repaired before

Ask for a price

You don’t need a survey visit. Photos are enough for us to price nearly every job: send a close-up, a wider shot and your postcode, and we will reply with a fixed price.

Dartford questions

When can you do it?

It depends on the time of year and where you are. We will offer you dates when we send your quote.

Can you redo someone else’s repair?

Usually, yes. The old repair comes out first, so mention it when you send pictures.

What happens next?

You get a fixed quote and available dates. If anything’s unclear, we will ask for another photo.

Is it safe with children and pets around?

Keep pets and children away from the work area on the day.

How do I book?

Send pictures through the quote form or call 0345 017 0787, and we will take it from there.

What if the damage is worse than the pictures show?

We’ll show you and explain before doing anything extra. Nothing extra is done without your say-so.

Will you leave a mess?

Very little mess: we sheet and mask everything nearby, and we leave the room clean.

Is a repair better than a new one?

In most cases, yes. Replacement brings removal, refitting and making good, which a repair avoids. We’ll be honest if it’s not worth it.
