Window mastic for Whitchurch Hill homes and businesses

Landlords, agents and businesses in Whitchurch Hill

We work for landlords and agents as well as householders. Resealing between tenancies keeps a property looking cared for before the next move-in.

Window mastic in Whitchurch Hill

The new joint doesn’t have to be white. White, brown, anthracite grey, black and clear sealants are all available, so the bead blends with the window rather than framing it. Typical jobs include cold air getting in at the frame edge and gaps left after new windows were fitted, across uPVC windows, composite doors and aluminium frames.

Homes in small places like Whitchurch Hill often stand in the open, with little to shelter their windows from wind and rain. That exposure dries out and cracks the mastic around frames and sills faster.

All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

Whitchurch Hill questions

Do you work for landlords with property near Pangbourne station?

Yes, landlords and agents are among the people we work for. You can phone 0345 464 0079 or email us with the details for a clear quote.

Do you cover smaller places like Whitchurch Hill?

Yes. Whitchurch Hill is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Just mention lanes, gates or anything else about the route when you book.

Do you work for hotels and businesses?

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.

Do you take out the old sealant first?

Yes. All of the old material is cut out and the joint cleaned before resealing.

Can you match the sealant to my frames?

Yes. We can use white, brown, anthracite grey, black or clear, so the joint suits the frame.

Is it messy?

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

Are you ARBOMaster approved?

Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we’re part of it.

Is it worth trying it myself?

Some simple jobs can be done by a careful DIYer. Most DIY failures come from sealing over old material, wet joints or too much sealant.

What sealant work can’t fix

A few problems are outside what sealant work can do:

  • Draughts through the window seals rather than the frame
  • Penetrating damp from a failed cavity tray or render
  • A failed sealed unit that has misted up

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

Joints and surfaces we work on

  • Timber windows & doors
  • uPVC windows
  • Patio & French doors
  • Aluminium frames
  • Window sills
  • Composite doors

Why act early in Whitchurch Hill

Working on frames from a ladder with a sealant gun isn’t easy, especially upstairs. A professional job is cut out properly, backed where needed and finished neatly, in a sealant suited to the wall. Where a wall is exposed, as many are in small places like Whitchurch Hill, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.

Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.

Why Whitchurch Hill customers choose us

  • Approved under the ARBOMaster scheme
  • Quality sealants from Arbo and Everbuild
  • Any old sealant cut out fully, not covered over
  • We leave the area clean and tidy

How to look after the new joints

So the new joints stay in good condition:

  • Keep timber frames painted
  • Clean frames with a soft cloth and soapy water
  • Air rooms to keep condensation down around windows
  • Clear any debris from frame drain holes

On timber frames, keep the paintwork in good order, because bare, wet timber moves more and pulls at the joint. Paint up to the joint, not over the silicone.

A small gap around a frame only grows. As the old mastic shrinks further, more air gets through, and heat escapes around the frame. A new joint closes it up.

Can I do it myself?

A DIY attempt does not rule out a professional job. We remove it and do the joint properly.

If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.

Signs you need window mastic in Whitchurch Hill

Joints that are too thin or too deep fail early. A thin smear across a wide gap has nothing to it, while a joint packed solid cannot stretch. That’s what backing rod is for.

Most people get in touch after spotting something like this:

  • Cracked internal joints between frame and plaster
  • Untidy mastic left by window fitters
  • A bead that doesn’t match the frame
  • Rain getting in at the frame or under the sill

For an older house near a landmark such as St John the Baptist, frames set in older brick or stone need a sealant that suits the wall as well as the frame.

How to choose a mastic man

What we do, step by step

Our applicators work methodically: protect, prepare, seal, tidy. Typically it takes anything from an hour or two to a full day, depending on how many frames there are, and the area is left clean. In a small place like Whitchurch Hill, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We check how each frame can be reached safely.
  2. Old, cracked mastic is removed completely, along with any loose debris.
  3. Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
  4. Deep voids are backed, then the sealant is gunned in.
  5. The joint is shaped to shed water and the area tidied.

Before we arrive

  • Tell us about access, such as stairs, a lift or high-level joints
  • Let us know if you’ve seen damp or leaks
  • Move anything stored near the joints

Windows and doors in Whitchurch Hill

Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Basildon Park (about 2 miles west) are a reminder that the area around Whitchurch Hill 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.

Letting a property close to Pangbourne station? Then renewing tired window mastic between tenants heads off draught and damp complaints. For site and facilities teams at buildings such as The Oratory Preparatory School, its window and door frames need their mastic kept sound, just like a home’s.
