Peaslake Window Mastic

Problem with your window and door frames in Peaslake? We cut out the old, prepare the joints and apply the right sealant, and the work is guaranteed for a year.

  • Cracked or shrunken mastic around the frame
  • Water coming in at the bottom corners of a door
  • Draughty joints inside around the window

Aftercare tips

Once the sealant has cured, a few habits help it last:

  • Clean frames with a soft cloth and soapy water
  • Wipe condensation off the frames
  • Paint up to the joint, not over it
  • Look round the frames every year or so

Keep the new mastic undisturbed while it cures, following the cure time we give you. Keep jet washers away from the frames.

A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and a cold room gets colder. A new joint closes it up.

How we handle window mastic in Peaslake

Frames and walls do not move together. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. So the sealant has to stretch and recover, which is why we use a low-modulus product. If you have sealant in the wrong colour for the frame and hard, cracked sealant around windows, we can help, on window sills, timber windows & doors and composite doors alike.

Mastic can only go onto a dry, clean joint, so window work in Peaslake is booked around the forecast. Let us know about access to all the frames, upstairs ones included.

Big or small, you get the same one-year guarantee.

Landlord and commercial work in Peaslake

Letting agents often deal with us directly. Send the address, what’s needed and the access arrangements.

For anyone letting property in or around Peaslake, several properties can go on one quote. Just tell us the addresses and what each one needs.

The process

Good joint work is mostly preparation, so that is where we spend the time. Every joint is cleaned and dried before new material goes in. In total, it generally takes anything from an hour or two to a full day, depending on how many frames there are. For a village or hamlet like Peaslake, the journey is planned in advance: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.

  1. First we look at every frame and agree the list.
  2. The old mastic is cut out and the surfaces cleaned back.
  3. We fit backing rod in deep gaps so the sealant is the right depth.
  4. We apply a weatherproof sealant to match the frame and tool it neatly.
  5. Every joint is checked before we leave.

Getting ready for the visit

  • Mention any sign-in or site rules at work premises
  • Mention if the joints have been sealed before
  • Let us know if you’ve seen damp or leaks

Your questions about window mastic in Peaslake

Is Peaslake within the area you cover?

Yes, Peaslake is covered. We work across London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

Can you help a landlord with a rental near Gomshall station?

Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we will give you a clear price.

Is it worth trying it myself?

You can, for simple jobs. Preparation is everything: all the old sealant out, and a clean, dry joint. We can always put it right if it fails.

Will you leave a mess?

No. We work neatly, protect the area around the joints and tidy up afterwards.

Is there any odour?

That depends on the sealant. Some products have a noticeable smell, others very little.

Can you get sealant to suit coloured frames?

Yes, we choose a colour to suit the frame. Grey and black frames get grey or black sealant, and wood-effect frames generally suit brown.

Do you remove the old sealant?

Yes. We cut out all the old sealant and clean the joint before resealing.

Where are you based?

Our base is Crawley. Our area covers South East England, London and Scotland.

How the job changes by surface

Timber windows & doors

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

Window sills

Stone and concrete sills have their own joints, including the one between the sill and the frame above. We seal those with a sealant suited to masonry.

Do you need window mastic in Peaslake?

On timber frames, paint and putty build up around the joint. Mastic painted over many times cracks with the paint, and the wood moves with damp as well as heat.

Keep an eye out for any of the following:

  • Rain getting in at the frame or under the sill
  • Draughty joints inside around the window
  • Cold air getting in at the frame edge
  • White mastic on grey or black frames

For landlords with property near Gomshall station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.

Questions to ask before you book

  • What the quote includes, VAT included or not
  • What insurance they hold
  • What happens if they find a problem under the old sealant
  • How long to leave it before use

Our hiring checklist

Window mastic in Peaslake: 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. Historic houses like Chilworth Manor (about 4.2 miles north-west) are a reminder that the area around Peaslake has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window.

In the older streets around Church of St Mark, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

What we cannot put right

Some problems need a builder, plumber or other trade rather than us:

  • Damp coming through the wall itself rather than the frame joint
  • Condensation trapped between the panes
  • Worn gaskets, brush seals or a door that has dropped

How we quote for window mastic

We do not publish a price list, because no two jobs are the same. What we look at:

  • The product the joint needs
  • The old material and how stubborn it is

Every job is a little different, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.

  • How many joints, rooms or windows are involved
  • Any access issues, like height or stairs
