  • Draughts coming in around windows and doors

Window mastic near South Benfleet

What happens if it’s left?

Working on frames from a ladder with a sealant gun is not easy, especially upstairs. We cut out properly, back deep gaps and tool every joint neatly, in a sealant suited to the wall. Around South Benfleet, water from a failed joint in an older home can soak into timber and plaster, and that is a much bigger job than renewing the sealant.

Some things make a job bigger or smaller: the old material and how easily it comes out, whether mould needs treating, and whether we need extra access for height. We take all of that into account in your quote.

Why book with us

  • Old sealant always removed completely
  • We agree the colour with you first
  • 20+ years of sealant experience
  • Sanitary silicone with an anti-fungal additive in wet areas

How we handle window mastic in South Benfleet

A window frame and the wall around it expand and shrink at different rates. 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. We are often asked to deal with cracked sealant at the sill ends and cracked or shrunken mastic around the frame, on patio & French doors, uPVC windows and aluminium frames.

Around South Benfleet, conservatories, garden rooms and patio doors are often part of the house. Their glazing joints and frame seals are as much a part of the job as the windows, and any older timber or sash windows need a sealant that suits them.

All our work is covered by a one-year guarantee, wherever you are in Essex.

Window mastic in South Benfleet: local notes

South Benfleet is close to 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. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Rented homes near Benfleet station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. For an older house near a landmark such as Church of St Mary the Virgin, the joint between an old wall and a newer frame is generally the first place rain gets in.

For landlords and businesses

Housing providers, facilities teams and property managers book us too in South Benfleet and across Essex. We can quote a run of properties together.

Hotels need rooms back in use, so the work can be planned room by room. We’ve worked in hotels as well as homes and businesses.

Can I do it myself?

If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.

If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so just mention it when you contact us.

Common questions in South Benfleet

Is South Benfleet within the area you cover?

Yes, South Benfleet is covered. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

Does the coastal weather in South Benfleet affect outside sealant?

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.

What do you put in the joint?

Each joint gets the product that suits it. Where it moves, gets wet or faces the weather makes a difference.

Does the work come with a guarantee?

Yes, for 12 months. Keeping drainage clear and checking the joints yearly helps them last.

Can you work on commercial sites?

Yes, regularly. We can plan bigger jobs in stages to suit the site.

How do I get a quote for window mastic in South Benfleet?

There’s no set price, as it depends on the job: its size, the old material, access and the product needed. You’ll get a clear quote before we start.

Can you quote for more than one area?

Of course. Combining jobs makes good use of the visit.

How long should I leave it?

Most sealants are touch-dry well before they’re fully cured. We’ll tell you how long to leave the joint before we leave.

Do you need window mastic in South Benfleet?

Timber windows bring their own problems. Mastic painted over many times cracks with the paint, and the wood moves with damp as well as heat.

Look out for these signs:

  • Gaps where the sill meets the wall
  • Hard, cracked sealant around windows
  • Damp patches on the reveal after heavy rain
  • Gaps between the frame and the inside reveal

Managing a site like Kents Hill Infant School? Then its window and door frames need their mastic kept sound, just like a home’s.

What happens on the day

Before we leave, we go over the finished joints with you. The visit itself normally takes a few hours for a few frames, or a day or more for a whole house, depending on the amount of work. A visit to South Benfleet 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 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. Every joint is checked before we leave.

How to prepare

  • Let us know if you’ve seen damp or leaks
  • Clear the area around the work
  • Plan for the work area to be out of bounds to pets and children

Advice

Surface by surface

uPVC windows

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

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.

Honest limits

Before booking, it’s worth knowing the limits too:

  • Faulty window hardware
  • Penetrating damp from a failed cavity tray or render
  • Worn gaskets, brush seals or a door that has dropped

Not sure which it is? You can phone 0345 464 0079 or send us an email and we’ll tell you honestly before you book.
