Window mastic in Houghton

Why it’s worth doing now in Houghton

Failed mastic isn’t a reason to replace sound windows. Where the frames are sound, new mastic normally deals with draughts and leaks at the edges. If we find failed glass units or worn seals, we will tell you. Older cottages and farmhouses around Houghton can have timber floors and frames, where water from a failed joint can cause rot if it’s left.

There are no prices on our website, because each job is priced on what it involves. For a quick quote, please phone 0345 464 0079 or email us.

How we handle window mastic in Houghton

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. Our applicators cut it out and replace it with a flexible, weatherproof sealant. We’re often asked to deal with hard, cracked sealant around windows and mastic that’s falling out in pieces, across aluminium frames, uPVC windows and composite doors.

Mastic can only go onto a dry, clean joint, so window work in Houghton is booked around the forecast. Let us know about access to all the frames, upstairs ones included.

Each job carries a 12-month guarantee.

For landlords and businesses

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.

Hotels need rooms back in use, so we plan the work room by room around your bookings where we can. We’ve worked in hotels as well as homes and businesses.

DIY versus a professional finish

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

Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.

Window mastic in Houghton: local notes

Historic houses like Mottisfont Abbey (about 3.2 miles south) are a reminder that the area around Houghton has older buildings as well as new. Where a home is older, older timber frames in brick or stone need a different approach from a modern uPVC window. Rainfall in the South East is lower than in much of the UK, 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 All Saints, frames set in older brick or stone need a sealant that suits the wall as well as the frame. For site and facilities teams at buildings such as Test Valley School, larger buildings have plenty of frames, and the mastic around each one ages.

Surface by surface

uPVC windows

We clean the frame edge carefully so the plastic is not marked, then the sealant goes in between frame and wall.

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.

What we do, step by step

Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from an hour or two to a full day, depending on how many frames there are, and the area is left clean. In a small place like Houghton, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. Each frame is looked over and we agree which ones need resealing.
  2. The old mastic is cut out and scraped back to clean surfaces.
  3. Where the gap is deep, backing rod goes in first.
  4. The new sealant goes on in white, brown, anthracite grey, black or clear to suit.
  5. We tool each bead neatly and check every joint is closed.

How to prepare

  • Try not to wet indoor joints just before the visit
  • Mention any leaks or damp you’ve noticed
  • Tell us about any previous sealing or DIY attempts

Advice

What affects the quote in Houghton

The price is agreed before any work begins. It’s based on:

  • How many rooms, windows or areas are involved
  • Whether the work is at height
  • Mould in or behind the old joints
  • The old material and how stubborn it is

Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Asking for a quote

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

  • How we’d reach the joints
  • How many joints, rooms or windows are involved
  • Any previous sealing or DIY work
  • The problem you’ve noticed

For a quote, ring 0345 464 0079 or send us an email with the location and a short description of the problem. We will give you a clear price before any work starts.

Questions from Houghton

Do you cover smaller places like Houghton?

Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

Can you do window mastic in Houghton?

Yes. Our work covers London and the South East, and Houghton is part of that. Just ring 0345 464 0079 or drop us an email with a few details of the job, and we’ll send you a clear quote.

Do you seal inside as well as outside?

Yes. Draughts often come through the inside gap too, so sealing both is often worthwhile.

Do you hold any approvals?

Yes. Mr Mastic is an ARBOMaster approved applicator.

Can I add another job to the visit?

Yes. Just list everything you need and we will quote it together.

Will new mastic stop draughts?

Often, yes. Air often gets in between the frame and the wall, and sealing the inside and outside joints closes that path.

Can you seal over the old sealant?

No. The old sealant always comes out first, so the new sealant bonds properly.

Can you work on commercial sites?

Yes. We work in offices, washrooms, hotels and other commercial premises, as well as homes. We can talk about working times when we quote.

Signs you need window mastic in Houghton

Joints that are too thin or too deep fail early. A skim of sealant over a wide gap soon tears, and a gap filled solid cannot flex. That is what backing rod is for.

It’s worth asking for a quote if you see:

  • Mastic that’s falling out in pieces
  • Rain getting in at the frame or under the sill
  • Draughts coming in around windows and doors
  • A bead that doesn’t match the frame

Letting a property close to Mottisfont & Dunbridge station? Then renewing tired window mastic between tenants heads off draught and damp complaints.

Questions to ask before you book

  • Whether they’re fully insured
  • What product goes in the joint
  • Whether you can choose the colour
  • What the quote includes, VAT included or not
