Window mastic in Jaywick, done properly

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. If you have hard, cracked sealant around windows and water coming in at the bottom corners of a door, we can help.

Around Jaywick, 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.

The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

Jaywick questions

Do you cover smaller places like Jaywick?

Yes, smaller places are covered as well as towns. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.

Does the coastal weather in Jaywick 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.

Do the sealants smell?

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

Do you remove the old sealant?

Yes. All of the old material is cut out and the joint cleaned.

How much does window mastic cost in Jaywick?

Size, access and the old material all affect the cost. Call for a quick quote and we’ll talk you through it.

Do you have insurance?

Yes. We’re fully insured.

Do you guarantee window mastic?

Yes. Every job comes with our one-year guarantee, and we’re ARBOMaster approved applicators.

Do you work for letting agents?

Yes, we do. Domestic, commercial and hotel work are all part of what we do, and we’re fully insured.

Frames and glazing around Jaywick

Jaywick is close to the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. 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, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

For an older house near a landmark such as St Christopher, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall. For site and facilities teams at buildings such as Sir Martin Frobisher Academy, the mastic around its windows and doors needs looking after like any other building’s.

Jaywick is about 2 miles south-west of Clacton-on-Sea, in Essex. Our applicators cover window mastic for homes and businesses in Jaywick and nearby. Across Essex, we cover 644 places, Jaywick among them. Chelmsford is on our list too, around 27 miles away.

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’s fine. We cut it out and start again.

Looking after it afterwards

Once the sealant has cured, a few habits help it last:

  • Keep jet washers away from the mastic
  • Check the mastic once a year
  • Paint up to the joint, not over it
  • Make sure the drainage slots aren’t blocked

Silicone can’t usually be painted, so if you are planning to paint the frames or walls, tell us beforehand. There are paintable sealants for joints that need it.

Wet, windy weather is when failed mastic shows itself, but resealing works best in dry conditions. Sorting cracked mastic early means the joint is sound before the bad weather.

Honest limits

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

  • Soft or decayed wood in the frame
  • Worn gaskets, brush seals or a door that has dropped
  • A sash or casement that won’t close properly

If in doubt, call 0345 464 0079 or email us and we’ll say what we think.

Where we work in Jaywick

  • uPVC windows
  • Composite doors
  • Window sills
  • Timber windows & doors
  • Patio & French doors
  • Aluminium frames

How the job changes by surface

Patio & French doors

Heavy door frames can move more than windows. The sealant must cope with it.

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.

Do you need window mastic in Jaywick?

A lot of older mastic was never designed to stay flexible. Once it’s rigid, every bit of frame movement pulls at it, leaving a hairline gap down one side.

The most common problems we see are:

  • Rushed sealant from a window installation
  • Gaps between the frame and the inside reveal
  • Black, perished sealant on frames
  • Draughts coming in around windows and doors

For landlords with property near Clacton-On-Sea station, renewing tired window mastic between tenants heads off draught and damp complaints.

How to choose a mastic man

Landlords, agents and businesses in Jaywick

We also work for businesses, from offices to washrooms and kitchens. On commercial sites, working times can be discussed when we quote.

Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. Several properties can go on one quote.

How the visit works

Our applicators work methodically: protect, prepare, seal, tidy. For most jobs that takes a few hours for a handful of frames, longer for a whole house and we leave things clean and tidy. Parking around Jaywick 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. First, we go round the frames with you and agree the list.
  2. The old mastic is cut out and scraped back to clean surfaces.
  3. Deep gaps get closed-cell backing rod to set the depth.
  4. A flexible exterior sealant is applied in a colour to suit the frame.
  5. Every joint is tooled smooth and checked before we leave.

Before we arrive

  • Keep children and pets away from the work area
  • For business premises, tell us about site rules or sign-in
  • For indoor joints, keep the area dry beforehand if you can
