Window Mastic in Easthorpe

We cover Easthorpe for mastic around window and door frames, sills and patio doors. Old material cut out, joints cleaned and sealed neatly.

  • Cold air getting in at the frame edge
  • Sealant in the wrong colour for the frame
  • Cracked sealant at the sill ends

Keeping the joints in good condition

How long the joints last depends on use and care. Here’s what we suggest:

  • Keep drainage slots and sill grooves clear
  • Walk round the house once a year and look at the joints
  • Avoid blasting the frames with a pressure washer
  • Keep paint and stain on wooden frames in good order

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.

Wet, windy weather is when failed mastic shows itself, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.

Colour matters on a frame. We can seal in white, brown, anthracite grey, black or clear, so the line suits the frame instead of standing out. If you have rain getting in at the frame or under the sill and black, perished sealant on frames, we can put it right, on aluminium frames, uPVC windows and patio & French doors alike.

Homes in small places like Easthorpe 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.

All our work comes with a 12-month guarantee, wherever you are in Essex.

Honest limits

Sealant is not the answer to every problem, and we’d rather say so up front. It will not solve:

  • A sash or casement that won’t close properly
  • Damp coming through the wall itself rather than the frame joint
  • A door that needs adjusting, rehanging or new seals

If in doubt, call 0345 464 0079 or drop us an email and we will say what we think.

Surfaces we seal

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

For landlords and businesses

We regularly work with letting and managing agents. Send the address, what’s needed and the access arrangements and we’ll quote.

Mouldy or split sealant often shows up at the end of a tenancy, and it’s easy to sort out between tenants. Several properties can go on one quote.

What window mastic looks like in Easthorpe

With historic houses such as Layer Marney Tower (about 2.7 miles south) nearby, there’s older building stock in the area around Easthorpe as well as newer homes. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that is traditional sand mastic. 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.

Rented homes near Marks Tey station change hands often, and cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets. In the older streets around Church of St Mary, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

  • Whether old sealant or filler has to be cut out
  • How many areas need sealing
  • The size of the job
  • The type of sealant required

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

Asking for a quote

To help us quote quickly, let us know:

  • Pictures of the joints, sent by email
  • What’s wrong with the joints now
  • Access, such as stairs, a lift or height
  • How many joints, rooms or windows are involved

We quote each job on its own, so the first step is telling us about yours. Simply phone 0345 464 0079 or drop us an email and describe the job, and pictures are welcome.

What the job involves on each surface

Composite doors

An exposed front door gets wind-driven rain. We pay most attention there.

Patio & French doors

Water at the foot of a door frame is not always the mastic: blocked drain slots, worn brush seals and threshold details can let water in too. We look for the cause first.

How the visit works

You don’t need to clear the whole room or building, just the space around the work. Everything nearby is protected, and the job takes a few hours for a few frames, or a day or more for a whole house in most cases. Somewhere like Easthorpe needs a little journey planning: tell us about narrow lanes, gates, long drives and where we can park. We bring what the job needs, so it can be finished in one trip where possible.

  1. First, we go round the frames with you and agree the list.
  2. We remove the old mastic and clean the frame edge and wall.
  3. Where the gap is deep, backing rod goes in first.
  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.

Preparing for the visit

  • Clear the area around the work
  • Plan for the work area to be out of bounds to pets and children
  • Where the joints are inside, avoid wetting them before we arrive

What information do you need?

Let us know what needs doing and where, plus photos if you have them. We will ask anything else we need to know.

Are you an approved applicator?

Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.

Is it worth trying it myself?

You can, for simple jobs. The key is preparation: remove all the old material and work on a clean, dry joint. If it doesn’t work out, we can redo it.

Do you do commercial work?

Yes. We’ve worked for hotels, offices and other businesses.

How many windows can you do in a day?

Do the sealants smell?

Possibly a little. Any smell clears as the sealant cures.

Should I try it myself first?

The biggest DIY mistake is sealing over old sealant. Silicone does not stick to old silicone, so it peels away and traps moisture behind it. All the old material has to come out first.

Not every job suits DIY: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
