Sand mastic near Whitchurch Hill

How we handle sand mastic in Whitchurch Hill

Traditional burnt sand mastic that sits naturally against stone and brick. It suits period and listed homes, where modern sealant can look out of place. We work on tenement windows, sash and case windows and period & listed homes, and the jobs we see most are gaps where the frame meets the masonry and cracked mastic round a front door frame.

Somewhere as small as Whitchurch Hill, older homes often have timber frames set in stone or brickwork. Not every older frame suits a modern silicone bead, so the sealant has to be chosen to suit the building.

We guarantee the work for a year. If there’s a problem with our work within the year, let us know and we’ll sort it.

Why it’s worth doing now in Whitchurch Hill

Cement-based fillers and modern sealants don’t always suit a period surround. Sand mastic is the like-for-like choice, which can matter on listed and conservation-area homes. 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.

Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Call for a quick quote and we will go through it with you.

What sand mastic looks like in Whitchurch Hill

With historic houses such as Basildon Park (about 2 miles west) nearby, there’s older building stock in the area around Whitchurch Hill as well as newer homes. 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, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.

If you let a flat or house near Pangbourne station, older sash windows in a rental need their mastic kept sound to keep the weather out. Managing a site like The Oratory Preparatory School? Then larger buildings have plenty of frames, and the mastic around each one ages.

When to call us in Whitchurch Hill

Timber swells and shrinks with the weather. That movement opens up the mastic joint over time.

Any of these means the joints need attention:

  • Patchy fillers round a sash window
  • Failed mastic on an exposed elevation
  • Gaps round a timber door in stone or brick
  • Window mastic to renew ahead of painting

For an older house near a landmark such as St John the Baptist, the windows may be timber, sash or later replacements, and each needs the right sealant against the wall.

Questions to ask before booking

  • Whether you can choose the colour
  • What happens if the job turns out different
  • Whether the sealant suits the joint
  • Whether all the old sealant comes out first

Our hiring checklist

Landlords, agents and businesses in Whitchurch Hill

If you manage several properties in or around Whitchurch Hill, several properties can go on one quote. Send us the addresses and the work at each, and pictures by email help.

Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Resealing at the right time is simple maintenance that we can handle for you.

DIY sealant or a professional job?

If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.

The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.

What happens on the day

When we get to you, we compare the joints with what we discussed. If anything is different, we explain it before carrying on. After that, the work takes a few hours for a single window, longer for several. Somewhere as small as Whitchurch Hill, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.

  1. We look at the surrounds with you and agree the joints to renew.
  2. Old mastic and any loose material are raked out.
  3. We pack any deep voids first.
  4. We apply the mastic by hand and shape it.
  5. We dress the finish so it sits neatly against the masonry.

Preparing for the visit

  • Try not to wet indoor joints just before the visit
  • Mention if the joints have been sealed before
  • Clear items away from the joints we’re working on
