Is Ansteadbrook within the area you cover?

How do I get a quote for external mastic in Ansteadbrook?
We do not publish prices, because the cost depends on the job: how much there is, what’s there now, how we reach it and what it needs. You’ll get a clear quote before we start.
Do you work for hotels and businesses?
Yes. We have worked for hotels, offices and other businesses.
What colours does the sealant come in?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We choose the closest to your brick or render so the joint doesn’t draw the eye.
Do you work at height?
That depends on how high the joints are and the ground below. Low-level joints are straightforward; for higher ones, send details and we will confirm the access.
What sealant do you use?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll tell you what we are using.
How we handle external mastic in Ansteadbrook
A movement joint is only as good as its depth. Closed-cell backing rod sets the depth and stops the sealant sticking to the back, leaving it bonded to two faces so it can move with the wall. Typical jobs include weathered mastic that no longer stretches and plants rooting in failed movement joints, on joints between brick and frames, concrete & block and copings & trims.
In a village or hamlet like Ansteadbrook, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.
The work is covered for a year after we finish. If anything is not right with it, phone 0345 464 0079 or send us an email.

What else we do in Ansteadbrook
Why it’s worth doing now in Ansteadbrook
A properly done movement joint is an even line in a colour that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner so it’s worth doing right. Where a wall is exposed, as many are in small places like Ansteadbrook, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
Leaving a failed joint usually makes the job bigger, not smaller, as water and mould keep getting in. If you’re not sure whether it needs doing, call 0345 464 0079 or send us an email for an honest opinion and a quote.

DIY sealant or a professional job?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly, so tell us about it when you ask for a quote.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. The common mistakes are sealing over old sealant, sealing a damp joint and using far too much.
How it works
Most of a good job is in the preparation, and we don’t rush it. Joints are cleaned back and dried before anything new goes in. In total, it normally takes a few hours to a few days, depending on the length of joint and the access. In a small place like Ansteadbrook, access is usually the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
How to prepare
- Let us know if you’ve seen damp or leaks
- Try not to wet indoor joints just before the visit
- For business premises, tell us about site rules or sign-in

What we are called out for in Ansteadbrook

The most common problems we see are:
- Leaking joints around cladding and façade panels
- Moss and dirt in joints with no sealant left
- Joints with sealant missing in places
- Joints where the bead has come unstuck
For landlords with property near Haslemere station, split movement joints are easy to miss on a rental until damp shows inside.

- Adding movement joints to masonry that has none
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
