Window mastic in Kingsey, done properly

A window frame and the wall around it expand and shrink at different rates. Plastic and aluminium frames move with the temperature, while masonry stays fairly still. That’s why the joint needs a flexible, low-modulus sealant rather than something rigid. Typical jobs include cracked or shrunken mastic around the frame and rushed sealant from a window installation, across timber windows & doors, aluminium frames and window sills.

In a village or hamlet like Kingsey, older cottages and farmhouses often have timber windows set in stone or brick. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.

All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Windows and doors in Kingsey

London and the South East are among the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Rented homes near Haddenham & Thame Parkway station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Homes close to Parish Church of St Nicholas include some older properties, and the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Why act early in Kingsey

Redecorating is a good moment to renew the mastic. Fresh joints finish the job neatly, and it’s easier while the walls are being worked on anyway. In a small place like Kingsey, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.

Combining jobs into one visit is generally more efficient than separate visits, so tell us about everything that needs sealing. We’ll send you a clear quote for the lot.

Can I do it myself?

Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas need the right product, the right access and the right method.

The biggest DIY mistake is sealing over old sealant. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.

What the job involves on each surface

Composite doors

Draughts round the door leaf generally come from worn seals or adjustment, not the mastic. We will tell you if that is what we find.

Patio & French doors

The joints around patio doors run a long way, top, sides and threshold. The threshold and the bottom corners take the most water, so we pay close attention there.

What affects the quote in Kingsey

We do not publish a price list, because jobs vary so much. What we look at:

  • How many areas need sealing
  • Mould in or behind the old joints
  • Access and height
  • Working hours on commercial sites

Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed. Call for a quick quote and we will go through it with you.

What to tell us for a quote

To make quoting easier, please include:

  • The problem you’ve noticed
  • Roughly how big the job is
  • A few pictures by email, if you can
  • Any access issues, like height or stairs

For a quick quote, get us on the phone, or email us if that’s easier. Tell us about the joints that need doing and we will explain what’s involved.

Aftercare tips

Looking after new joints is easy, and it makes a real difference:

  • Make sure the drainage slots are not blocked
  • Ventilate rooms so frames do not stay wet inside
  • Keep timber frames painted
  • Avoid blasting the frames with a pressure washer

Timber frames need their paint kept up, because bare, wet timber moves more and pulls at the joint. Paint up to the joint, not over the silicone.

A failed joint lets water into the wall a little at a time. You might not see it until plaster blows or a damp patch appears inside. Early resealing stops it reaching that point.

How it works

The work is kept neat and contained to the joints we are treating, so you can carry on as normal. Expect the work to take a few hours for a few frames, or a day or more for a whole house, and we explain the cure time before we leave. For a village or hamlet like Kingsey, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. 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. All the failed sealant is cut away, along with any loose debris.
  3. Frame and wall are cleaned and must be dry before sealing.
  4. Backing rod fills deep voids and the sealant goes in on top.
  5. The joint is shaped to shed water and the area tidied.

Preparing for the visit

  • Where the joints are inside, avoid wetting them before we arrive
  • Let us know about stairs, lifts or work at height
  • For business premises, tell us about site rules or sign-in

Ask for a quote

Every job is quoted individually, so the first step is telling us about yours. Simply phone 0345 464 0079 or email us and describe the job, and pictures are welcome.

Advice

When to call us in Kingsey

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. Backing rod sets the right depth.

Any of these means the joints need attention:

  • Hard, cracked sealant around windows
  • Old mastic that has gone black or come away
  • Whistling draughts around closed windows
  • A bead that does not match the frame

Managing a site like Haddenham St Mary's Church of England School? Then its window and door frames need their mastic kept sound, just like a home’s.
