When to call us in Blackmore End

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.

Keep an eye out for these signs:

  • Burns on sills
  • Damage during building work
  • Scratches from ladders and furniture
  • Chips and dents

How to compare quotes

Blackmore End: your questions answered

Can a burnt window sill be fixed?

Yes. The burn is filled and refinished to match.

Do I need to be at home?

Someone needs to let us in and show us the job. You do not need to watch us work.

Which areas do you work in?

We work UK-wide. Our prices are the same everywhere.

What if the damage is worse than the pictures show?

If we find something the pictures didn’t show, we explain it first. The price only changes if you agree.

I rent my home. Can I book you?

Yes, though it’s best to check with your landlord first. Many landlords are happy for a repair to be arranged.

Do you repair coloured uPVC?

Yes. We recreate the colour and grain by hand.

Can you repair several things at once?

Yes, and it’s frequently cheaper. Just add the extra items to your photos and we will quote them together.

Can landlords book you?

Yes. We carry out repairs for homeowners, landlords, letting agents, builders and businesses across Hertfordshire.

Landlord and trade work in Blackmore End

We work for landlords, letting agents and housing providers in Blackmore End as well as homeowners. A repair between tenants keeps the property empty for less time, and it generally costs far less than a refit.

We regularly work with letting and managing agents. Just send pictures, the address and how to get access.

Repairing versus replacing in Blackmore End

Replacing the frame or sill is a much bigger job, and new uPVC may not match the weathered frames around it. Repairing the damage keeps the original. Prices start from £95. Set against the cost of replacement, a repair is usually a fraction of the price, because nothing has to be taken out, refitted or made good. The quote lists exactly what you’re paying for.

DIY repairs versus a professional job

A DIY attempt isn’t a disaster. We remove the old filler and start again, so it will not stop us repairing it. 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.

When a repair is not the answer

In fairness, there are a few things a repair won’t fix:

  • 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 before you book.

Surfaces we repair

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

How we price uPVC repair

Repairs from £95. We charge the same across the UK, including Blackmore End. The price reflects:

  • Where the damage is and how we get to it
  • What kind of damage it is
  • Unusual colours or finishes
  • Whether old repairs or coatings need taking off

There are no surprise 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.

Send pictures for a quote

You can generally get a fixed quote without us visiting. To help us price it:

  • A coin beside the damage so we can judge size
  • What it’s made of, if you know
  • Whether it’s been repaired or coated before
  • A close-up of the damage, in focus

If you are in Blackmore End and want a price, pictures are the quickest way: a close-up, a wider shot and your postcode. We reply with a fixed quote and our next available dates.
