Window mastic near Hillgrove

Can I do it myself?

If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

A careful DIYer can reseal a simple joint, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Window mastic for homes and businesses in Hillgrove

A window frame and the wall around it expand and shrink at different rates. Heat and cold make frames grow and shrink against brick or render that hardly moves. That is why the joint needs a flexible, low-modulus sealant rather than something rigid. Common call-outs are for rain getting in at the frame or under the sill and white mastic on grey or black frames, across window sills, patio & French doors and composite doors.

In a village or hamlet like Hillgrove, 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.

Big or small, you get the same 12-month guarantee in Hillgrove and across the Isle of Wight.

What the job involves on each surface

uPVC windows

The frame is cleaned with a product that will not harm the plastic, then the sealant goes in between frame and wall.

Timber windows & doors

Wood swells when it’s wet and shrinks when it dries, so the joint must stay flexible. The paint or stain needs to be sound where the sealant meets it.

The process

We keep the work tidy and contained to the area we are working on, so you can get on with your day. 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. In a small place like Hillgrove, access is generally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. Each frame is looked over and we agree which ones need resealing.
  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. 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

  • Where the joints are inside, avoid wetting them before we arrive
  • Let us know about stairs, lifts or work at height
  • Let us know if you’ve seen damp or leaks

Hillgrove homes and the weather

Historic houses like Arreton Manor (about 2.4 miles south) are a reminder that the area around Hillgrove has older buildings as well as new. Where a home is older, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic. 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 Smallbrook Junction station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. If you look after a building such as Wootton Community Primary School, larger buildings have plenty of frames, and the mastic around each one ages. For an older house near a landmark such as St. Mark's Church, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

What sealant work can’t fix

Before booking, it’s worth knowing the limits too:

  • Rotten timber, which needs a joiner first
  • Condensation trapped between the panes
  • Penetrating damp from a failed cavity tray or render

If you are not sure, just call 0345 464 0079 or email us and we will give you a straight answer before you book.

Surfaces we seal

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

Keeping the joints in good condition

A little care helps the new joints last. Our advice:

  • Avoid blasting the frames with a pressure washer
  • Walk round the house once a year and look at the joints
  • Do not use solvent cleaners on the joint
  • Ventilate rooms so frames do not stay wet inside

Keep the new mastic undisturbed while it cures, following the cure time we give you. Don’t point a pressure washer at the joints.

On timber windows, water behind the joint can lead to rot. Once wood has rotted, it needs repair before it can be sealed, so early resealing is worth it.
