Different surfaces, different methods
Timber windows & doors
Older timber windows in stone or brick can suit sand mastic rather than modern sealant. We’ll tell you which suits your home.
Window sills
Masonry sills can have joints where water gets in, and the joint under the frame can let rain run behind. Those are sealed with a product suited to stone or concrete.
How we handle window mastic in Westfield
The new joint does not 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. We work on composite doors, aluminium frames and uPVC windows, and people most often call us about untidy mastic left by window fitters and rain getting in at the frame or under the sill.
Homes around Westfield range from older properties to newer houses, and their windows range just as widely. Each frame material needs the right sealant against the right wall.
Your job is guaranteed for a year, as with all our work.

Work for landlords, hotels and businesses
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
In hotels, rooms out of use cost money, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Keep timber frames painted
- Do not aim a pressure washer at the joints
- Ventilate rooms so frames don’t stay wet inside
- Use gentle cleaners on frames and sealant
A yearly look round the frames is enough. Small splits are simple to catch before they leak.
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. Catching it early keeps the fix to a reseal.
What we do, step by step
Most of a good job is in the preparation, so that’s where we spend the time. Every joint is cleaned and dried before new material goes in. All told, the work takes a few hours for a handful of frames, longer for a whole house. Parking around Westfield is generally easier than in a town centre, but mention any lanes, gates or long drives. If the job is outside, tell us about side access and how high the joints are.
- First, we confirm safe access to each frame.
- Old, cracked mastic is removed completely, along with any loose debris.
- Frame and wall are cleaned and must be dry before sealing, and primed where the sealant calls for it.
- Backing rod fills deep voids and the sealant goes in on top.
- The joint is shaped to shed water and the area tidied.
Before we arrive
- On commercial sites, let us know about site rules
- Plan for the work area to be out of bounds to pets and children
- Try not to wet indoor joints just before the visit

Signs you need window mastic in Westfield
On timber frames, paint and putty build up around the joint. Mastic painted over many times cracks with the paint, and timber moves with moisture as well as temperature.
People normally contact us after spotting something like this:
- Hard, cracked sealant around windows
- Draughty joints inside around the window
- Sealant in the wrong colour for the frame
- Cracked sealant at the sill ends
Rented homes near Woking station change hands often, and renewing tired window mastic between tenants heads off draught and damp complaints.

Asking for a quote
When you contact us, it’s useful to know:
- How we’d reach the joints
- The type of property
- Whether it has been sealed before
- The address or postcode of the job

Why deal with it now?
A cracked joint around a frame lets rain into the wall. Over time that can mean damp patches, damaged plaster and rotting timber. Resealing now is a small job by comparison. Homes in smaller places like Westfield can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.

Westfield homes and the weather
London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. Historic houses like Clandon Park (about 4.1 miles south-east) are a reminder that the area around Westfield has older buildings as well as new. In older buildings, older frames set in brick or stone need a sealant that suits them, and sometimes that’s traditional sand mastic.
If you live in an older home near St Mark's Church, frames set in older brick or stone need a sealant that suits the wall as well as the frame. Managing a site like Westfield Primary School? Then larger buildings have plenty of frames, and the mastic around each one ages.
