How the visit works

There’s no need to move everything out before we come, only the area right around the joints. We protect the rest, and the work takes most of a day for a typical house, less for a few frames for a typical job. Somewhere as small as Heads Hill, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We check each frame and agree which ones need doing.
  2. Next the failed sealant is cut away and the joint cleaned.
  3. We fit backing rod in deep gaps so the sealant is the right depth.
  4. New exterior sealant goes on in a matching colour and is tooled smooth.
  5. Finally we tidy up and check each joint.

Before we arrive

  • Let us know if you’ve seen damp or leaks
  • Tell us about access, such as stairs, a lift or high-level joints
  • Mention any parking rules near the property

Window mastic in Heads Hill, done properly

The new joint doesn’t have to be white. White, brown, anthracite grey, black and clear sealants are all available, so the bead blends with the window rather than framing it. If you are dealing with cold air getting in at the frame edge and damp patches on the reveal after heavy rain, we can help, on composite doors, window sills and patio & French doors alike.

Somewhere as small as Heads Hill, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.

Whatever the size of the job, you get the same one-year guarantee.

Keeping the joints in good condition

After the cure time, these simple habits help:

  • Keep paint and stain on wooden frames in good order
  • Keep paint off silicone joints
  • Ventilate rooms so frames do not stay wet inside
  • Keep solvents and bleach off the sealant

Clean the frames with mild soapy water, and avoid solvent cleaners on the sealant.

Draughts get worse, not better. As old mastic keeps shrinking, the gap widens, and a cold room gets colder. Resealing closes it.

Why it’s worth doing now in Heads Hill

A quick bead over the top of old mastic looks like an easy fix, but new sealant can’t bond to old, crumbling mastic. It soon lifts and the leak carries on behind it. Proper resealing starts with removing the old joint. Where a wall is exposed, as many are in small places like Heads Hill, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

Leaving a failed joint generally makes the job bigger, not smaller, because water and mould keep working on it. If you are not sure whether it needs doing, phone 0345 464 0079 or drop us an email and we will give you an honest view and a quote.

What we can’t put right

Honest advice matters more to us than a booking, so here’s what sealant can’t fix:

  • Damp problems in the wall away from the window
  • Draughts through the window seals rather than the frame
  • A failed sealed unit that has misted up

If in doubt, call 0345 464 0079 or drop us an email and we will say what we think.

Signs you need window mastic in Heads Hill

Plenty of failed mastic was poorly applied in the first place. Mastic laid onto dusty, damp or crumbling surfaces never bonded as it should, and it lets go sooner than it should.

Common reasons people contact us are:

  • Cracked or shrunken mastic around the frame
  • White mastic on grey or black frames
  • Rushed sealant from a window installation
  • Damp patches on the reveal after heavy rain

For an older house near a landmark such as Church of St Peter, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

What your quote should include

  • Whether all the old sealant comes out first
  • What guarantee comes with the work
  • How much experience the applicator has
  • How the surfaces are prepared before sealing

10 questions to ask before you book

Different surfaces, different methods

uPVC windows

Plastic frames move a lot between a hot afternoon and a cold night, so the joint needs a low-modulus sealant that stays flexible. White is the usual colour, with brown, anthracite grey and black for coloured frames.

Composite doors

An exposed front door gets wind-driven rain, and the top and bottom corners tend to fail first. Those corners get the most care.

Windows and doors in Heads Hill

Historic houses like Shaw House (about 3.3 miles north-west) are a reminder that the area around Heads Hill has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. 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.

For landlords with property near Thatcham station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Schools such as Cheam School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.
