What sealant work can’t fix

We won’t take on work that will not last, so here’s what sealant cannot put right:

  • Damp coming through the wall itself rather than the frame joint
  • Soft or decayed wood in the frame
  • Broken hinges, locks or handles

If in doubt, phone 0345 464 0079 or drop us an email and we will say what we think before booking.

Where we work in Tilehurst

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

Window mastic in Tilehurst, done properly

Frames and walls do not move together. 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. If you have damp patches on the reveal after heavy rain and gaps between the frame and the inside reveal, we can put it right, on aluminium frames, window sills and uPVC windows alike.

Many houses in smaller places like Tilehurst have conservatories, garden rooms or patio doors. Their glazing joints and frame seals are as much a part of the job as the windows.

You get a 12-month guarantee, the same in Tilehurst as everywhere else we work.

What we do, step by step

All our tools and materials come with us in the van, so there’s nothing for you to buy. Once we have agreed what’s being done, we protect the area and start. It normally takes a few hours for a few frames, or a day or more for a whole house. In a smaller place like Tilehurst, parking is seldom the issue; lanes, gates and long drives are worth mentioning. If the job is outside, tell us about side access and how high the joints are.

  1. First we look at every frame and agree the list.
  2. Next the failed sealant is cut away and the joint cleaned.
  3. Where gaps are deep, backing rod goes in first.
  4. New exterior sealant goes on in a matching colour and is tooled smooth.
  5. We clear up and check every joint is fully closed.

Before we arrive

  • Clear the area around the work
  • Mention if the joints have been sealed before
  • Mention any sign-in or site rules at work premises

Keeping the joints in good condition

So the new joints stay in good condition:

  • Use gentle cleaners on frames and sealant
  • Avoid blasting the frames with a pressure washer
  • Repaint timber before it’s bare
  • Keep paint off silicone joints

Silicone cannot usually be painted, so mention any painting plans before any work starts. We can use a paintable sealant where that matters.

Leaks generally show up in wet, windy weather, but sealant goes on best when frames and walls are dry. Sorting cracked mastic early means the joint is sound before the bad weather.

Do you need window mastic in Tilehurst?

Water runs down the glass onto the sill, so the sill ends and the joint below the frame are common leak points. When that sealant fails, water gets into the wall or under the frame.

Signs it’s time to call us include:

  • Rushed sealant from a window installation
  • Mastic that has split away from the wall
  • Draughts coming in around windows and doors
  • Rain getting in at the frame or under the sill

Homes close to Tilehurst Methodist Church include some older properties, and frames set in older brick or stone need a sealant that suits the wall as well as the frame.

What your quote should include

  • When the joint can take water or movement
  • What happens if the job turns out different
  • How the surfaces are prepared before sealing
  • The length of the guarantee

What affects the cost of window mastic

  • How much old sealant there is and how hard it is to remove
  • Working hours on commercial sites
  • The type of sealant required
  • How many areas need sealing

  • If someone has resealed it before
  • A few photos by email, if you can
  • How we’d reach the joints
  • Roughly how big the job is

Letting agents often deal with us directly. Tell us the address, the job and how access works and we will give you a quote.

How the job changes by surface

Aluminium frames

Bi-fold and sliding aluminium doors have long frame joints, and the bottom joint sees the most water. We prepare and reseal every joint, backing the deep ones.

uPVC windows

The frame is cleaned with a product that will not harm the plastic, then the new bead is laid against the frame and the wall and tooled smooth.

Frames and glazing around Tilehurst

With historic houses such as Mapledurham House (about 1.6 miles north) nearby, there’s older building stock in the area around Tilehurst as well as newer homes. In older buildings, 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.

If you look after a building such as Park Lane Primary School, larger buildings have plenty of frames, and the mastic around each one ages. Rented homes near Tilehurst station change hands often, and sound mastic around windows and doors keeps out the draughts and damp that tenants notice first.
