Window mastic in Gushmere

Window mastic in Gushmere

Every window and door frame has a gap around it, and mastic is what closes it. 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 timber windows & doors, patio & French doors and aluminium frames, and people most often call us about gaps left after new windows were fitted and draughts coming in around windows and doors.

Homes in small places like Gushmere often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.

Big or small, it’s backed by our one-year guarantee in Gushmere and across Kent.

For landlords and businesses

Failed sealant is one of the commonest items on a check-out report, and it’s quick to put right between tenancies. Several properties can go on one quote.

Housing providers, facilities teams and property managers book us too in Gushmere and across Kent. We can quote a run of properties together, and we are fully insured.

Why deal with it now?

If you’re painting or rendering, reseal at the same time. Fresh joints finish the job neatly, and it’s easier while the walls are being worked on anyway. Where a wall is exposed, as many are in small places like Gushmere, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

A few things move the cost up or down: the old material and how easily it comes out, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.

Why book with us

  • Homes, businesses and hotels
  • One-year guarantee on every job
  • Over 20 years’ experience
  • You choose the colour before work begins

DIY versus a professional finish

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.

If you do try it yourself, take your time over the preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.

What affects the cost of window mastic

The price is agreed before any work begins. It takes into account:

  • How easy the joints are to reach
  • Any mould that needs treating
  • How much old sealant there is and how hard it is to remove
  • How many rooms, windows or areas are involved

Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.

What we need to know

The more you tell us, the more accurate the quote. When you get in contact, it helps to mention:

  • Any previous sealing or DIY work
  • How many joints, rooms or windows are involved
  • What’s wrong with the joints now
  • Access, such as stairs, a lift or height

Asking for a quote is easy: let us know the job and the location and its rough size. Photos by email help us understand the job.

The process

You don’t need to clear the whole room or building, only the area right around the joints. We protect the rest, and the job takes anything from an hour or two to a full day, depending on how many frames there are for a typical job. For a village or hamlet like Gushmere, 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 how each frame can be reached safely.
  2. Old, cracked mastic is removed completely.
  3. The surfaces are cleaned and left dry.
  4. Deep voids are backed, then the sealant is gunned in.
  5. The joint is shaped to shed water and the area tidied.

Preparing for the visit

  • Try not to wet indoor joints just before the visit
  • Mention any tricky access
  • On commercial sites, let us know about site rules

Getting a quote

Every job is quoted individually, so the first step is telling us about yours. Just phone 0345 464 0079 or drop us an email with the details, and photos are welcome.

Do you need window mastic in Gushmere?

Joint shape matters as much as the product. A skim of sealant over a wide gap soon tears, while a joint packed solid can’t stretch. Backing rod sets the right depth.

Keep an eye out for these signs:

  • Gaps left after new windows were fitted
  • Rain getting in at the frame or under the sill
  • A bead that doesn’t match the frame
  • Black, perished sealant on frames

Letting a property close to Selling station? Then cracked frame mastic tends to show up as a draught or damp complaint, so it’s worth checking between lets.

How to choose a mastic man

Windows and doors in Gushmere

Historic houses like Belmont House and Gardens (about 3.6 miles west) are a reminder that the area around Gushmere has older buildings as well as new. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window. 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.

Managing a site like Selling Church of England Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages. In the older streets around Church of St Mary, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Your questions about window mastic in Gushmere

Do you work for landlords with property near Selling station?

Yes, rental work is part of what we do. Just call 0345 464 0079 or send us an email and tell us about the property, and we will send you a clear quote.

Will you come out to Gushmere?

Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.

Can new sealant go over the old?

No. New silicone won’t bond to old silicone, and anything trapped underneath, including mould and water, stays there. We remove it all first.

What information do you need?

Just the basics: where it is, what you’ve noticed and how we reach it. After that, simply ring 0345 464 0079 or drop us an email.

Where do you work from?

We are based in Crawley, and we work across South East England, London and Scotland.

Are you fully insured?

Yes. Mr Mastic is fully insured.

Will resealing my frames help with draughts?

Yes, where the draught is at the frame edge. We find where the air is coming from before we reseal.

How long before the joint can be used?

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

How the job changes by surface

Window sills

Stone and concrete sills have their own joints, including the one between the sill and the frame above. Those are sealed with a product suited to stone or concrete.

uPVC windows

Fitters’ mastic on plastic frames is sometimes thin and rushed. We cut it out, back any deep gaps and reseal properly.
