Repairing versus replacing in Gelli-deg

Replacing the frame or sill costs far more, and it may not match the rest after years of weathering. A repair keeps the original. Our uPVC repair starts from £95. Set against the cost of replacement, repairing normally costs far less, because nothing has to be taken out, refitted or made good. The quote lists exactly what you are paying for.

Should I try a DIY kit first?

If you’ve already tried a DIY fix, that’s fine. We remove the old filler and start again, so it does not stop a professional repair. It does add a little time, so tell us about it when you send photos.

DIY kits are sold for most surfaces, and they can make a small mark look better. The trouble is colour and preparation: kits come in a few standard shades, and without proper cleaning and keying the filler often lifts.

Gelli-deg: your questions answered

It’s been repaired before. Can you still fix it?

Generally, yes. Tell us what was done before and we’ll plan for it.

Can tenants book a repair?

We can work for tenants, landlords or agents. Just make sure the landlord agrees.

What information do you need?

Some photos, your postcode and how to reach you. On the day, access to the room.

Can you repair several things at once?

Yes. Doing several items on one visit generally costs less than separate visits. Include pictures of each item.

Are you a vetted contractor?

We are accredited with CHAS, Constructionline, SafeContractor, SMAS Worksafe and Builder’s Profile.

Are there extra charges for Gelli-deg?

No. Our quotes include travel, with the same prices everywhere we work.

Will you leave a mess?

We protect the room with dust sheets and masking first, and we clean up when we’ve finished.

Is my repair covered?

Yes, for a year. If anything goes wrong with the repair within the year, we return to fix it.

For landlords and businesses

If you manage property in Gelli-deg, we’ll quote for several properties at once. Just send photos for each address and we will price them together.

Letting agents often 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.

What uPVC repair costs

Prices start from £95. We give every job a fixed price from pictures. These are the things that affect it:

  • How hard the colour is to match
  • How easy the damage is to reach
  • Whether old repairs or coatings need taking off
  • How many items we do on one visit

A repair normally costs much less than people expect, especially compared with replacing and refitting. Send photos and we will give you the exact figure.

Quotes from your photos

Before you send photos, a few simple things make all the difference:

  • Your postcode, so we can check dates
  • One sharp close-up of the damage
  • Any details about the material
  • A coin or ruler next to the damage for scale

For most jobs, photos are all we need to give you a price. Add a line about what happened and your postcode, and we’ll reply with a fixed quote and the earliest dates we have.

When to call us in Gelli-deg

uPVC is tough but not indestructible: ladders and building work leave scratches and chips, candles and cigarettes burn sills, and removed fittings leave holes.

If you can see any of these, send us a picture:

  • Damage during building work
  • Burns on sills
  • Scratches from ladders and furniture
  • Holes from removed fittings and alarms

Before booking anyone

  • What preparation is included
  • How soon you can use it again
  • How long the guarantee is and what it covers
  • Whether the colour is mixed to match

Our hiring checklist

What a repair cannot fix

  • Broken locks, hinges or mechanisms
  • Frames that are warped or out of square

Not sure? Send pictures and we will give you a straight answer.

  • Coloured and woodgrain uPVC
  • White uPVC

How it works

Your technician turns up at the time we agreed with you and checks the damage against your pictures first. The floor and nearby surfaces are covered before we open a single tin. Most visits take a morning or an afternoon, and we leave the room as we found it.

  1. We start by cleaning the frame.
  2. Scratches, chips and holes are filled.
  3. The repair is sanded smooth.
  4. We match the colour, including woodgrain finishes.
  5. The repair is blended into the surface around it.

How to prepare

  • Keep a parking space free if you can
  • Keep children and pets away from the room on the day
  • Have a window or extractor fan available

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. You will get a fixed quote, not an estimate.
