Common questions in Boughton under Blean

Is Boughton under Blean in your area for window mastic?

Yes. Our work covers London and the South East, and Boughton under Blean is part of that. You can ring 0345 464 0079 or email us and tell us what needs doing.

I let a flat near Selling station. Can you help?

Yes, rental work is part of what we do. You can phone 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before any work starts.

Do you have sealant for grey or black windows?

Yes. We can use white, brown, anthracite grey, black or clear, so the joint suits the frame.

Will the old sealant be removed?

Always. Sealing over the old bead is the commonest cause of early failure, so we never do it.

Is it OK to seal over old sealant?

No, because it fails. We remove every bit of old sealant first, so the new sealant bonds properly.

Can you work on commercial sites?

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

Will new mastic stop draughts?

It will if the frame joint is the problem. We find where the air is coming from before we reseal.

Do you guarantee window mastic?

Yes. All our work carries a 12-month guarantee, and we are ARBOMaster approved applicators.

How we handle window mastic in Boughton under Blean

If you can feel air around a shut window, the gap is often at the frame. Resealing that joint can make a room feel noticeably less draughty. If the draught is through the window seals instead, we’ll tell you. Typical jobs include draughty joints inside around the window and leaking joints at the ends of sills, on uPVC windows, window sills and composite doors.

Outdoor sealant needs dry, clean surfaces, so work on frames around Boughton under Blean is planned for dry weather. Let us know about access to all the frames, upstairs ones included.

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

Window mastic in Boughton under Blean: local notes

Rainfall in the South East is lower than in much of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Letting a property close to Selling station? Then sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Schools such as Boughton-under-Blean and Dunkirk Primary School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s. If you live in an older home near St Barnabas, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

Quotes for window mastic in Boughton under Blean

You will get a clear quote before any work starts. It takes into account:

  • Access and height
  • Mould in or behind the old joints
  • How much there is to do
  • The type of sealant required

Asking for a quote

A few details help us give you an accurate quote. When you get in contact, it helps to mention:

  • Whether it’s a home or a business
  • What the problem is, such as mould, gaps, leaks or cracking
  • Where the property is
  • If someone has resealed it before

Call for a quick quote, or send an email if you’d rather. Tell us about the joints that need doing and we’ll explain what’s involved and send you a clear quote.

DIY versus a professional finish

The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.

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 does not work out, we can still put it right.

Why act early in Boughton under Blean

Once mastic fails, rain can get between the frame and the wall. Left long enough, it can stain inside walls, spoil plaster and rot wooden frames. A reseal is a much smaller job. Where a wall is exposed, as many are in small places like Boughton under Blean, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

Combining jobs into one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. We’ll give you a clear quote for the lot.

Honest limits

New sealant can’t fix everything, and we’d rather say so up front. Sealant won’t put right:

  • Worn gaskets, brush seals or a door that has dropped
  • Faulty window hardware
  • Soft or decayed wood in the frame

Landlord and commercial work in Boughton under Blean

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.

We work for landlords and agents as well as homeowners. Resealing between tenancies keeps a property looking cared for.

How to look after the new joints

How long the joints last depends on use and care. We suggest:

  • Avoid harsh chemicals near the mastic
  • Don’t aim a pressure washer at the joints
  • Keep paint and stain on wooden frames in good order
  • Wash the frames with mild soapy water

A yearly look round the frames is enough. Small splits are simple to catch before they leak.

On timber windows, water behind the joint can lead to rot. Rotten timber needs a joiner, not a sealant, so early resealing is worth it.

How it works

Once we’re on site, we compare the joints with what we discussed. If we find something unexpected, we talk it through with you first. After that, the work takes a morning for a couple of windows and a door. In a small place like Boughton under Blean, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We check how each frame can be reached safely.
  2. Old, cracked mastic is removed completely, along with any loose debris.
  3. The surfaces are cleaned and left dry, and primed where the sealant calls for it.
  4. Backing rod fills deep voids and the sealant goes in on top.
  5. We tool the joint so water runs off, then clear up.

Preparing for the visit

  • For indoor joints, keep the area dry beforehand if you can
  • Tell us about any water getting in
  • Let us know about parking restrictions
