Book window mastic in Rew Street

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.

A careful DIYer can reseal a simple joint, like a short, easy-to-reach joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.

Window mastic in Rew Street

Around Rew Street we seal all kinds of frames: uPVC, aluminium, timber and composite, plus patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. We are often asked to deal with water coming in at the bottom corners of a door and whistling draughts around closed windows, across patio & French doors, timber windows & doors and composite doors.

Mastic can only go onto a dry, clean joint, so window work in Rew Street is booked around the forecast. Let us know about access to all the frames, upstairs ones included.

The work is guaranteed for twelve months. If something is not right with it in that time, tell us and we will put it right.

Questions from Rew Street

Does the coastal weather in Rew Street affect outside sealant?

Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.

Is Rew Street within the area you cover?

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.

Can you seal over the old sealant?

No. Fresh sealant does not stick to old sealant, and it traps any mould or water underneath. We remove it all first.

How do I get a quote for window mastic in Rew Street?

Size, access and the old material all affect the cost. Ask us for a quote.

What do you put in the joint?

Products from Arbo and Everbuild, among others, chosen to suit the joint. We explain the product when we quote.

Will you leave a mess?

Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.

Can new window sealant be painted?

Not if it’s silicone. Tell us your decorating plans and we will pick a sealant to suit.

Can I add another job to the visit?

Yes, we can. More than one area can be quoted together.

How to look after the new joints

Good habits help new joints last longer. Our tips:

  • Make sure the drainage slots are not blocked
  • Do not paint over the silicone
  • Keep jet washers away from the mastic
  • Clean frames with a soft cloth and soapy water

Clean the frames with mild soapy water, and keep solvents and harsh chemicals off the joint.

Water trapped behind a failed joint can start rot in timber frames and sills. Rotten timber needs a joiner, not a sealant, so it pays to reseal before that happens.

Leave it or put it right?

Running fresh sealant over the old joint is tempting, but new sealant cannot bond to old, crumbling mastic. It peels before long, and water still gets in behind. Proper resealing starts with removing the old joint. In a small place like Rew Street, homes can be exposed to wind and rain, which finds any gap, and older walls, once damp, take a long time to dry.

Doing several joints on one visit generally makes better use of the time than several visits. You will get one clear quote for the whole job.

How we quote for window mastic

We do not publish a price list, because no two jobs are the same. The quote depends on:

  • Whether there’s mould to deal with
  • The type of sealant required
  • The old material and how stubborn it is
  • How many rooms, windows or areas are involved

What you pay reflects the work, not guesswork. That is why we ask a few questions first and give you a clear quote before any work starts.

Asking for a quote

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

  • What the problem is, such as mould, gaps, leaks or cracking
  • Photos by email, if that is easy
  • If it’s domestic, commercial or a hotel
  • Where the job is, and your postcode

The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints.

What we do, step by step

There isn’t much for you to do on the day. Point us to the joints and we’ll get on with it. The work itself takes a few hours for a few frames, or a day or more for a whole house from start to finish. In a small place like Rew Street, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. First, we go round the frames with you and agree the list.
  2. The old mastic is cut out and scraped back to clean surfaces.
  3. Deep gaps get closed-cell backing rod to set the depth.
  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.

Getting ready for the visit

  • Mention any sign-in or site rules at work premises
  • Mention any tricky access
  • Tell us about any previous sealing or DIY attempts

Window mastic in Rew Street: local notes

Rew Street is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on the mastic around window and door frames, which can dry out and crack sooner where a building faces the weather. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

For site and facilities teams at buildings such as Northwood Primary School, the mastic around its windows and doors needs looking after like any other building’s. If you live in an older home near All Saints' Church, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

How the job changes by surface

Composite doors

If the door itself is draughty, the issue may be the door seals or hinges rather than the frame mastic. We’ll tell you if that’s what we find.

Aluminium frames

Aluminium needs a sealant that bonds to coated metal and we avoid acetoxy silicones, which can react with some metals. Neutral-cure sealant is the safe choice.
