Window mastic for homes and businesses in Westwood

Homes in Westwood have every kind of window: uPVC, aluminium, timber and composite, along with patio doors, French doors and sills. The sealant is chosen to suit the frame material and the wall. We work on composite doors, uPVC windows and window sills, and the jobs we see most are gaps where the sill meets the wall and gaps left after new windows were fitted.

In a smaller place like Westwood, some walls face open ground and catch the full force of the weather, so exposed windows and doors face the weather head on. That is hard on the mastic around frames and sills.

All our work comes with a 12-month guarantee.

Windows and doors in Westwood

Westwood is within about 2 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. With historic houses such as Quex Park (about 2.9 miles west) nearby, there’s older building stock in the area around Westwood as well as newer homes. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic.

If you let a flat or house near Margate station, cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. For an older house near a landmark such as Parish Church of St John the Baptist, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Common questions in Westwood

Does the coastal weather in Westwood affect outside sealant?

Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.

Will you come out to Westwood?

Yes. Westwood is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Can I paint over the new sealant?

Not generally, if it’s silicone. Tell us your decorating plans and we will pick a sealant to suit.

Where do you work from?

Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.

Which products do you use?

The product depends on the job: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. We use products from Arbo and Everbuild.

How long should I leave it?

It depends on the product and the conditions. We tell you how long to leave it before we go.

Will new mastic stop draughts?

Yes, where the draught is at the frame edge. We find where the air is coming from before we reseal.

Should I try DIY first?

Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

What happens if it’s left?

Redecorating is a good moment to renew the mastic. Fresh joints finish the job neatly. Homes in smaller places like Westwood can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.

Doing several joints on one visit is usually more efficient than separate visits, so it’s worth mentioning everything you’d like done. You’ll get one clear quote for the whole job.

Quotes for window mastic in Westwood

Some jobs are bigger than they look, and some smaller. The main factors:

  • How many areas need sealing
  • Any mould that needs treating
  • Which sealant suits the joint
  • How easy the joints are to reach

The cost reflects the work involved, not a rough estimate. That’s why we ask a few questions first and agree the price before starting.

How the job changes by surface

Composite doors

A composite door normally sits in a plastic outer frame, and the joint around it is sealed like a window. We match the colour to the frame.

Timber windows & doors

Where timber has rotted at the joint, it needs repairing first. We’ll point out any rot we find, as a joiner will need to deal with it.

What we’re called out for in Westwood

Joints that are too thin or too deep fail early. A thin smear across a wide gap has nothing to it, and a gap filled solid cannot flex. Backing rod sets the right depth.

Most people get in touch after spotting something like this:

  • Whistling draughts around closed windows
  • Rain getting in at the frame or under the sill
  • Hard, cracked sealant around windows
  • Gaps between the frame and the inside reveal

For site and facilities teams at buildings such as St Gregory's Catholic Primary School, larger buildings have plenty of frames, and the mastic around each one ages.

What your quote should include

  • Which colour the sealant will be
  • How the joint is cleaned and prepared
  • What happens if the job turns out different
  • Whether all the old sealant comes out first

Choosing a sealant specialist

Looking after it afterwards

To keep the joints looking good and working properly:

  • Paint up to the joint, not over it
  • Clean frames with a soft cloth and soapy water
  • Avoid harsh chemicals near the mastic
  • Make sure the drainage slots aren’t blocked

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

Water trapped behind a failed joint can start rot in timber frames and sills. Rotten timber needs a joiner, not a sealant, so it pays to reseal before that happens.

What happens on the day

Once we are on site, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a few hours for a few frames, or a day or more for a whole house. Parking around Westwood is usually easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.

  1. We check how each frame can be reached safely.
  2. All the failed sealant is cut away, along with any loose debris.
  3. The surfaces are cleaned and left dry, and primed where the sealant calls for it.
  4. Deep voids are backed, then the sealant is gunned in.
  5. The joint is shaped to shed water and the area tidied.

How to prepare

  • Mention any sign-in or site rules at work premises
  • Clear items away from the joints we are working on
  • Let us know if you’ve seen damp or leaks
