Landlord and commercial work in Brightlingsea

We also work for property managers and facilities teams. We can quote a run of properties together, and we are fully insured for the work.

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.

Window mastic in Brightlingsea

The mastic around a window or door seals the gap between the frame and the wall. Once that seal fails, wind and rain find the gap. The old mastic is removed and the joint resealed with a flexible exterior sealant. We work on composite doors, timber windows & doors and window sills, and common reasons people get in touch are gaps between the frame and the inside reveal and mastic that’s falling out in pieces.

In smaller places like Brightlingsea, homes range from older cottages to newer houses, with windows to match: timber, uPVC and aluminium. Each frame material needs the right sealant against the right wall.

Every job comes with our 12-month guarantee, wherever you are in Essex.

Keeping the joints in good condition

Joint life depends on how it’s used and looked after. Here’s what we suggest:

  • Clean frames with a soft cloth and soapy water
  • Paint up to the joint, not over it
  • Do not use solvent cleaners on the joint
  • Repaint timber before it’s bare

On timber frames, keep the paintwork in good order, because bare, wet timber moves more and pulls at the joint. Paint up to the joint, not over the silicone.

Water gets in quietly when mastic fails. Often the first sign is a damp patch inside or flaking paint on the reveal. Catching it early keeps the fix to a reseal.

Windows and doors in Brightlingsea

Brightlingsea is within about 1 mile of the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. That’s hard on the mastic around window and door frames, especially on the side facing the sea. 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 an older house near a landmark such as Church of St James, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. For landlords with property near Alresford station, renewing tired window mastic between tenants heads off draught and damp complaints.

How it works

You do not need to clear the whole room or building, only the area right around the joints. We protect the rest, and the job takes a few hours for a few frames, or a day or more for a whole house in most cases. A visit to Brightlingsea is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.

  1. We check how each frame can be reached safely.
  2. All the failed sealant is cut away, along with any loose debris.
  3. Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
  4. Deep voids are backed, then the sealant is gunned in.
  5. We tool the joint so water runs off, then clear up.

Getting ready for the visit

  • For business premises, tell us about site rules or sign-in
  • Try not to wet indoor joints just before the visit
  • Let us know about parking restrictions

Advice

Brightlingsea: your questions answered

Is window mastic in a coastal place like Brightlingsea any different?

Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.

Is Brightlingsea within the area you cover?

Yes, Brightlingsea is covered. We work across London and the South East, and smaller places are part of that. The journey is planned ahead, so it helps to know about access.

How long will my window job take?

The work takes a few hours for a few frames, or a day or more for a whole house. Access and the amount of old mastic make the biggest difference.

Can I do it myself?

That depends on the joint. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.

Where is Mr Mastic based?

We work from Crawley. Our applicators cover Brightlingsea.

Do the sealants smell?

Sometimes, a little. It fades as the sealant cures, and ventilation helps.

What do you put in the joint?

It depends on the joint: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. Brands we use include Arbo and Everbuild.

Do you work for letting agents?

Yes. As well as homeowners, we work for landlords, agents, businesses and hotels across Essex.

When something else is needed

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

  • Rotten timber, which needs a joiner first
  • Misting between the panes of a double-glazed unit (that needs a new unit)
  • Damp problems in the wall away from the window

If you’re not sure, just ring 0345 464 0079 or email us and we’ll give you a straight answer before booking.

Where we work in Brightlingsea

  • uPVC windows
  • Aluminium frames
  • Window sills

DIY sealant or a professional job?

Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

Some sealant jobs are within reach of a careful DIYer, like a short, easy-to-reach joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

Do you need window mastic in Brightlingsea?

Water runs down the glass onto the sill, so the sill ends and the joint below the frame are common leak points. When that sealant fails, water gets into the wall or under the frame.

People usually contact us after spotting something like this:

  • Leaking joints at the ends of sills
  • Draughts coming in around windows and doors
  • Cracked or shrunken mastic around the frame
  • Draughty joints inside around the window

If you look after a building such as Brightlingsea Primary School and Nursery, its window and door frames need their mastic kept sound, just like a home’s.
