Window mastic for homes and businesses in South Woodford

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. We’re often asked to deal with white mastic on grey or black frames and untidy mastic left by window fitters, on composite doors, patio & French doors and timber windows & doors.

From mansion-block windows to modern glazing in new flats, London has every kind of frame. Over the years, the sealant around them shrinks, cracks and pulls away, letting in draughts and water.

The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or email us.

Common questions in South Woodford

I let a flat near Wood Street station. Can you help?

Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just ring 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear quote.

Is parking an issue for window mastic in South Woodford?

London parking needs a little planning, so let us know about permits, bays or a driveway when you book. The visit is then planned around what’s available.

What do you put in the joint?

It depends on the joint: sanitary silicone where it gets wet, and sealants suited to movement or weather elsewhere. Brands we use include Arbo and Everbuild.

Do the sealants smell?

It depends on the product. Some products have a noticeable smell, others very little, and any smell fades as they cure.

What do you need from me for a quote?

Only a few details: the address or postcode, what’s wrong and any access issues. After that, simply phone 0345 464 0079 or drop us an email.

Can I add another job to the visit?

Yes, and it often makes sense. Doing several areas at once is usually more efficient, so mention them when you ask for a quote.

Do you take out the old sealant first?

Yes. We cut out all the old sealant and clean the joint before applying anything new.

Can you seal over the old sealant?

No, and we never do. It can look neat for a few weeks, but the new bead soon lifts. The old sealant has to come out completely.

What we do, step by step

Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. Most jobs then take a few hours for a few frames, or a day or more for a whole house. For a job in South Woodford, parking and access are the things to plan: tell us about permits, visitor bays or off-street space, which floor we’re working on and whether there’s a lift.

  1. We check each frame and agree which ones need doing.
  2. Next the failed sealant is cut away and the joint cleaned.
  3. Deep gaps are filled with backing rod to set the depth.
  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

  • Tell us about any previous sealing or DIY attempts
  • For business premises, tell us about site rules or sign-in
  • Clear the area around the work

Frames and glazing around South Woodford

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. Historic houses like Valentines Mansion (about 2.3 miles south-east) are a reminder that the area around South Woodford 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.

South Woodford is in London, so parking needs planning: tell us about permits, visitor bays or off-street space when you book. If you let a flat or house near Wood Street station, sound mastic around windows and doors keeps out the draughts and damp that tenants notice first. Schools such as Oakdale Infants' School are buildings too, and its window and door frames need their mastic kept sound, just like a home’s.

How the job changes by surface

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.

Aluminium frames

Large aluminium doors have long joints down each side and across the head, and the threshold joint takes a lot of water. We prepare and reseal every joint, backing the deep ones.

Why it’s worth doing now in South Woodford

Redecorating is a good moment to renew the mastic. A clean new bead makes new paint or render look finished, and it’s easier while the walls are being worked on anyway. In a London flat, a failed joint rarely stays your problem alone: water from a shower or window joint can reach the flat below, and gaps in fire-stopping matter to everyone in the building.

Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. Your quote takes all of that into account.

How to look after the new joints

So the new joints stay in good condition:

  • Walk round the house once a year and look at the joints
  • Repaint timber before it’s bare
  • Wash the frames with mild soapy water
  • Keep jet washers away from the mastic

Check the drainage slots in the frames aren’t blocked, so rain drains out rather than building up at the sealant.

Look out for the warning signs: cracks in the mastic, gaps you can see light through, damp on the reveal or mould around the inside of the frame. If you notice one, it’s time to get the joint looked at.
