Window mastic for Fewcott homes and businesses

Window mastic in Fewcott

Whether it’s one leaking patio door or every frame on the house, the work is priced before anything is done. To get one, ring 0345 464 0079 or email us with the number of frames and any access details. If you have mastic that’s falling out in pieces and untidy mastic left by window fitters, we can put it right, on composite doors, aluminium frames and window sills alike.

Around Fewcott, many homes face open ground, so their windows and doors take the full weather. Exposed frames and sills lose their mastic sooner than sheltered ones.

We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Window mastic in Fewcott: local notes

Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

If you live in an older home near Church of St Mary, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Surface by surface

Timber windows & doors

Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We’ll tell you which suits your home.

uPVC windows

The frame is cleaned with a product that will not harm the plastic, then the sealant goes in between frame and wall.

Why deal with it now?

A quick bead over the top of old mastic looks like an easy fix, but it won’t grip old, dirty sealant. It soon lifts and the leak carries on behind it. The old mastic has to come out. In a small place like Fewcott, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

Homes and businesses are quoted the same way: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we’ll go through it with you.

What we do, step by step

There’s no need to move everything out, only the area right around the joints. Everything nearby is protected, and the work takes a few hours for a handful of frames, longer for a whole house in most cases. Somewhere as small as Fewcott, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. Each frame is looked over and we agree which ones need resealing.
  2. The old mastic is cut out and scraped back to clean surfaces.
  3. Where the gap is deep, backing rod goes in first.
  4. A flexible exterior sealant is applied in a colour to suit the frame.
  5. We tool each bead neatly and check every joint is closed.

Before we arrive

  • Let us know about earlier repairs to the joints
  • Clear the area around the work
  • Keep children and pets away from the work area

What we cannot put right

We’d rather tell you now than do work that will not last, so these are the limits:

  • Soft or decayed wood in the frame
  • Condensation trapped between the panes
  • Damp problems in the wall away from the window

If in doubt, phone 0345 464 0079 or send us an email and we’ll say what we think.

What we seal

  • uPVC windows
  • Composite doors
  • Timber windows & doors
  • Aluminium frames
  • Window sills
  • Patio & French doors

Looking after it afterwards

Looking after new joints is easy, and it makes a real difference:

  • Avoid blasting the frames with a pressure washer
  • Don’t paint over the silicone
  • Wipe condensation off the frames
  • Keep solvents and bleach off the sealant

Clean the frames with mild soapy water, and keep solvents and harsh chemicals off the joint.

On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so it pays to reseal before that happens.

FAQs for Fewcott

Can you do window mastic in Fewcott?

Yes. Our work covers London and the South East, and Fewcott is part of that. Just call 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear quote.

Can you help a landlord with a rental near Bicester North station?

Yes, we work for landlords and agents. You can call 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before we start.

Do you seal inside as well as outside?

Yes. Outside is the weather seal; inside closes the gap to the plaster. We can do either or both.

Is it OK to seal over old sealant?

No. The old sealant always comes out first, so the new joint bonds to clean surfaces.

Can you work on commercial sites?

Yes. Hotels, offices and other businesses use us, and we are fully insured.

Do you remove the old sealant?

Yes, every time. New sealant won’t bond properly to old, so the joint is cleaned back first.

Is the work guaranteed?

Yes. Our 12-month guarantee covers every job.

Can you reach windows above the ground floor?

Yes, where they can be reached safely. Tell us about access when you get in touch and we’ll plan for it.

What we’re called out for in Fewcott

Sun, frost and rain wear sealant out. UV light hardens the outside of the bead, and over the years it loses its give, cracks and comes away.

If you can see any of these, it’s time to have the joints looked at:

  • Leaking joints at the ends of sills
  • Mastic that is falling out in pieces
  • Cracked or shrunken mastic around the frame
  • Rain getting in at the frame or under the sill

Letting a property close to Bicester North station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

What your quote should include

  • Which sealant they’ll use, and why
  • Whether all the old sealant comes out first
  • Whether VAT is included
  • How the joint is cleaned and prepared

For landlords and businesses

Letting agents often deal with us directly. Tell us the address, the job and how access works and we’ll quote.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
