Window mastic for Bampton homes and businesses

How we handle window mastic in Bampton

Around Bampton we seal all kinds of frames: from uPVC casements to timber and aluminium, along with patio doors, French doors and sills. Each gets a sealant chosen for the frame and the wall it meets. Typical jobs include gaps left after new windows were fitted and rain getting in at the frame or under the sill, on uPVC windows, timber windows & doors and composite doors.

Many houses in smaller places like Bampton have conservatories, garden rooms or patio doors. Their glazing joints and frame seals are as much a part of the job as the windows, and any older timber or sash windows need a sealant that suits them.

The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we’ll sort it.

DIY versus a professional finish

Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. All the old material has to come out first.

What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, and the work is guaranteed for a year.

What we’re called out for in Bampton

Sun, frost and rain wear sealant out. Sunlight dries the surface out, until it loses its stretch and starts to crack.

The problems people normally mention when they call include:

  • Old mastic that has gone black or come away
  • A bead that doesn’t match the frame
  • Rain getting in at the frame or under the sill
  • Cold air getting in at the frame edge

For an older house near a landmark such as Church of St Mary, replacement windows fitted into old openings often leave uneven gaps that need backing and a flexible joint.

Before you book anyone

  • Whether they’re fully insured
  • Is the old sealant removed completely?
  • How hidden problems are handled
  • Whether the sealant suits the joint

How to choose a mastic man

When it is not the sealant

It helps to know what we can’t do:

  • Damp problems in the wall away from the window
  • A door that needs adjusting, rehanging or new seals
  • A sash or casement that will not close properly

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

For landlords and businesses

In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.

Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Keeping joints in good order is simple maintenance that we can handle for you.

Your questions about window mastic in Bampton

Is Bampton within the area you cover?

Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.

What guarantee comes with window mastic in Bampton?

Every job comes with our one-year guarantee, wherever it is. We’re fully insured, and an ARBOMaster approved applicator.

Where are you based?

Our base is in Crawley, and we cover South East England, London and all of Scotland.

Can you work on commercial sites?

Yes. Commercial and hotel work is a large part of what we do, as well as homes. We can talk about working times when we quote.

How long should I leave it?

Different products cure at different speeds, so please follow the time we give you.

How much does window mastic cost in Bampton?

The cost depends on the size of the job, access and how much old sealant has to come out. Call for a quick quote and we’ll talk you through it.

Is it worth trying it myself?

That depends on the joint. High-level, external movement and fire-rated joints are professional jobs.

Do I have to be there?

Access is agreed with you when the job is booked. Indoors, that usually means someone at home.

How it works

On the day, there’s very little for you to do. Show us the job and we’ll take it from there. The work itself takes a few hours for a handful of frames, longer for a whole house from start to finish. Parking around Bampton is normally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.

  1. We check how each frame can be reached safely.
  2. All the failed sealant is cut away.
  3. The surfaces are cleaned and left dry.
  4. Backing rod fills deep voids and the sealant goes in on top.
  5. The joint is shaped to shed water and the area tidied.

How to prepare

  • Clear items away from the joints we are working on
  • Where the joints are inside, avoid wetting them before we arrive
  • Keep pets and children clear of the area while we work

Bampton homes and the weather

Historic houses like Longworth House (about 4.8 miles south-east) are a reminder that the area around Bampton has older buildings as well as new. Where a home is older, 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, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.

Schools such as Bampton CofE Primary 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

Composite doors

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

uPVC windows

Fitters’ mastic on plastic frames is sometimes thin and rushed. We cut it out, back any deep gaps and reseal properly.
