Window mastic for Domewood homes and businesses

Looking after it afterwards

After the cure time, these simple habits help:

  • Make sure the drainage slots aren’t blocked
  • Avoid harsh chemicals near the mastic
  • Keep jet washers away from the mastic
  • Keep paint and stain on wooden frames in good order

Have a look at the joints once a year, ideally after winter. Small splits are simple to catch before they leak, and if anything looks wrong, just ring 0345 464 0079 or send us an email.

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.

How we handle window mastic in Domewood

Most frames have an outside joint and an inside one. Outside, the mastic keeps rain out; the internal joint closes the gap to the plaster and stops draughts. Either or both can be done. We work on aluminium frames, uPVC windows and timber windows & doors, and people most often call us about rushed sealant from a window installation and draughts coming in around windows and doors.

Homes in small places like Domewood often stand in the open, with little to shelter their windows from wind and rain. Exposed frames and sills lose their mastic sooner than sheltered ones.

Each job carries a 12-month guarantee, large or small.

Different surfaces, different methods

uPVC windows

uPVC expands and contracts noticeably with temperature, so we use a flexible, low-modulus sealant. White is the usual colour, with brown, anthracite grey and black for coloured frames.

Window sills

Stone and concrete sills have their own joints, and the joint under the frame can let rain run behind. Those are sealed with a product suited to stone or concrete.

How it works

A visit follows a simple pattern: we look at the joints together, protect the area around them, do the work and clear up. It usually takes a few hours for a handful of frames, longer for a whole house. For a village or hamlet like Domewood, 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. We check each frame and agree which ones need doing.
  2. The old mastic is cut out and the surfaces cleaned back.
  3. Where gaps are deep, backing rod goes in first.
  4. We apply a weatherproof sealant to match the frame and tool it neatly.
  5. Finally we tidy up and check each joint.

How to prepare

  • Keep children and pets away from the work area
  • Clear items away from the joints we’re working on
  • Let us know about parking restrictions

Advice

Why it’s worth doing now in Domewood

The work is quick compared with the damage it prevents: the visit takes anything from an hour or two to a full day, depending on how many frames there are. Wait for damp to appear and there may be plaster and decorating to sort out too. Older cottages and farmhouses around Domewood can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

No two jobs are quite the same, 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.

Common questions in Domewood

Do you cover smaller places like Domewood?

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

I let a flat near East Grinstead station. Can you help?

Yes, we work for landlords and agents. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear price.

Can you get sealant to suit coloured frames?

Yes, in most cases. Mention the frame colour when you ask for a quote and we’ll match it as closely as we can.

Can new window sealant be painted?

Most silicone can’t be painted. If you plan to paint, tell us first and we can use a paintable sealant where it suits the joint.

Is it worth trying it myself?

For a simple, easy-to-reach joint, a careful DIYer can do a reasonable job. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

How do I get a quote for window mastic in Domewood?

It depends on the job, so we quote each one individually. To get one, phone 0345 464 0079 or drop us an email and let us know what needs doing and where.

Which products do you use?

It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.

Is there any odour?

Sometimes, a little. Any smell clears as the sealant cures.

What we cannot put right

It helps to know what we can’t do:

  • A door that needs adjusting, rehanging or new seals
  • A failed sealed unit that has misted up
  • Faulty window hardware

If you are not sure, just phone 0345 464 0079 or send us an email and we will give you a straight answer.

What window mastic looks like in Domewood

With historic houses such as Saint Hill Manor (about 3.5 miles south-east) nearby, there’s older building stock in the area around Domewood as well as newer homes. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.

For site and facilities teams at buildings such as Imberhorne School, its window and door frames need their mastic kept sound, just like a home’s. Letting a property close to East Grinstead station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

Signs you need window mastic in Domewood

Water runs down the glass onto the sill, so the sill ends and the joint below the frame are common leak points. Failed sealant there lets rain into the wall or behind the frame.

Keep an eye out for any of the following:

  • Gaps between the frame and the inside reveal
  • A bead that doesn’t match the frame
  • Gaps left after new windows were fitted
  • Mastic that’s falling out in pieces

Historic houses such as Saint Hill Manor, about 3.5 miles south-east, show how far back building around Domewood goes.
