Trusted window mastic in Lower Green

Window mastic in Lower Green

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. We work on timber windows & doors, patio & French doors and uPVC windows, and the jobs we see most are damp patches on the reveal after heavy rain and mastic that has split away from the wall.

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

All our work is covered by a one-year guarantee, wherever you are in Surrey.

Why deal with it now?

Failed mastic is not a reason to replace sound windows. If the frames and glass are in good order, resealing the joints is often all that’s needed. If we find failed glass units or worn seals, we will tell you. Where a wall is exposed, as many are in small places like Lower Green, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.

No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all make a difference, and we’ll explain the quote if you ask.

Why book with us

  • An ARBOMaster approved applicator
  • More than 20 years in sealant work
  • Experience in homes, commercial sites and hotels
  • Sealant colour chosen to suit

What happens on the day

On the day, we look over the joints with you first. We protect the surfaces around the joints before any work begins. The work normally takes anything from an hour or two to a full day, depending on how many frames there are. Somewhere as small as Lower Green, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.

  1. We check how each frame can be reached safely.
  2. Old, cracked mastic is removed completely.
  3. Frame and wall are cleaned and must be dry before sealing.
  4. Deep voids are backed, then the sealant is gunned in.
  5. We tool the joint so water runs off, then clear up.

How to prepare

  • Clear items away from the joints we’re working on
  • Tell us about access, such as stairs, a lift or high-level joints
  • Mention if the joints have been sealed before

Advice

Aftercare tips

No joint lasts for ever, but care makes a real difference. Our tips:

  • Avoid blasting the frames with a pressure washer
  • Wash the frames with mild soapy water
  • Do not paint over the silicone
  • Air rooms to keep condensation down around windows

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

A failed joint lets water into the wall a little at a time. You might not see it until plaster blows or a damp patch appears inside. Early resealing stops it reaching that point.

Different surfaces, different methods

Composite doors

Front doors take the weather head on, and the top and bottom corners tend to fail first. We pay most attention there.

Window sills

Sills catch the water running down the glass, so the joints at each end and underneath matter. They’re cut out and resealed with exterior sealant.

Lower Green: your questions answered

Do you work for landlords with property near Esher station?

Yes, rental work is part of what we do. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we will give you a clear quote.

Is Lower Green within the area you cover?

Yes, Lower Green is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.

Will resealing my frames help with draughts?

It will if the frame joint is the problem. We find where the air is coming from before we reseal.

Can I add another job to the visit?

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

Are you insured?

Yes. Mr Mastic is fully insured.

Can I do it myself?

Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.

What does window mastic cost?

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. We agree the price before any work begins.

How many windows can you do in a day?

The work takes most of a day for a typical house, less for a few frames. Access and the amount of old mastic make the biggest difference.

Landlord and commercial work in Lower Green

In hotels, rooms out of use cost money, so we plan the work room by room. We have worked in hotels as well as homes and businesses.

We work for letting agents and landlords as well as householders. Sealant work between tenants is a simple way to keep a property in good order before the next move-in.

What window mastic looks like in Lower Green

The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind. With historic houses such as Hampton Court Palace (about 1.9 miles north-east) nearby, there’s older building stock in the area around Lower Green as well as newer homes. In older buildings, older timber frames in brick or stone need a different approach from a modern uPVC window.

Homes close to Church of All Saints include some older properties, and replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint. Rented homes near Esher station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints. For site and facilities teams at buildings such as Cranmere Primary School, the mastic around its windows and doors needs looking after like any other building’s.
