How we quote for window mastic

We don’t publish a price list, because no two jobs are the same. What we look at:

  • How much there is to do
  • The type of sealant required
  • How many areas need sealing
  • When we can work, for business premises

Doing several joints on one visit usually makes better use of the time than several visits, so tell us about everything that needs sealing. We will give you a clear quote for the lot.

Helping us quote

Photos by email are helpful but not essential. Try to tell us:

  • Any access issues, like height or stairs
  • Any previous sealing or DIY work
  • Roughly how big the job is
  • What’s wrong with the joints now

We quote each job on its own, so the first step is telling us about yours. Just ring 0345 464 0079 or email us with the details, and pictures are welcome.

Window mastic in West Hanney, done properly

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. The old mastic is removed and the joint resealed with a flexible exterior sealant. If you are dealing with leaking joints at the ends of sills and gaps between the frame and the inside reveal, we can put it right, on uPVC windows, aluminium frames and patio & French doors alike.

Around West Hanney, many homes face open ground, so their windows and doors take the full weather. That exposure dries out and cracks the mastic around frames and sills faster.

A 12-month guarantee comes as standard, so you are not left on your own once the job is done.

Leave it or put it right?

Running fresh sealant over the old joint is tempting, but it won’t grip old, dirty sealant. It peels before long, and water still gets in behind. The old mastic has to come out. Where a wall is exposed, as many are in small places like West Hanney, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

A failed joint rarely gets cheaper to fix by waiting, because water and mould keep working on it. If you are not sure whether it needs doing, phone 0345 464 0079 or email us for an honest opinion and a quote.

When it is not the sealant

We’d rather tell you now than do work that will not last, so these are the limits:

  • Draughts through the window seals rather than the frame
  • Penetrating damp from a failed cavity tray or render
  • Broken hinges, locks or handles

Not sure which it is? You can ring 0345 464 0079 or email us and we’ll tell you honestly.

Where we work in West Hanney

DIY sealant or a professional job?

Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.

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

Frames and glazing around West Hanney

Historic houses like Longworth House (about 4.2 miles north) are a reminder that the area around West Hanney has older buildings as well as new. 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.

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

Questions from West Hanney

Is window mastic in West Hanney guaranteed?

All our work, in West Hanney and everywhere else, comes with a 12-month guarantee. We are fully insured, and an ARBOMaster approved applicator.

Do you cover smaller places like West Hanney?

Yes, smaller places are covered as well as towns. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.

Do you do commercial work?

Yes. Hotels, offices and other businesses use us and we are fully insured.

Will there be a smell?

Possibly a little. It fades as the sealant cures, and ventilation helps.

How much does window mastic cost in West Hanney?

We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before any work starts.

What do you put in the joint?

We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice.

Will the old sealant be removed?

Yes. Sealing over the old bead is the commonest cause of early failure, and it’s something we never do.

Can you seal over the old sealant?

No, it won’t last. It can look neat for a few weeks, but the new bead soon lifts. Removing the old sealant completely is the only lasting way.

The process

There is not much for you to do on the day. Show us the job and we will take it from there. The job generally takes a few hours for a few frames, or a day or more for a whole house. For a village or hamlet like West Hanney, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.

  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. Every joint is tooled smooth and checked before we leave.

Before we arrive

  • Tell us about any previous sealing or DIY attempts
  • Tell us about access, such as stairs, a lift or high-level joints
  • Tell us about any water getting in

Getting a quote

A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints, and email photos if that’s easy.

Advice

What we are called out for in West Hanney

Joint shape matters as much as the product. A thin smear across a wide gap has nothing to it, and a gap filled solid cannot flex. Backing rod sets the right depth.

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

  • Hard, cracked sealant around windows
  • Old mastic that has gone black or come away
  • Gaps left after new windows were fitted
  • Gaps between the frame and the inside reveal

Homes close to Church of St James include some older properties, and the joint between an old wall and a newer frame is generally the first place rain gets in.

Before you book anyone

  • What the cure time is
  • Who does the work, and how experienced they are
  • Whether they’re fully insured
  • How the joint is cleaned and prepared
