External mastic for Brook and the surrounding area: the right sealant, proper preparation and a neat finish. Ask us for a quick quote.
- Joints where the bead has come unstuck
- Movement joints with cracked, split or missing sealant
- Rigid filler in a joint that should flex
Can I do it myself?
The difference is mostly in the preparation and the product. Joints are cleaned back to sound surfaces and dried, and the sealant is matched to the joint and its conditions.
A DIY attempt doesn’t rule out a professional job. We cut it out and start again.
External mastic in Brook, done properly
Ground-floor and low-level joints are straightforward to reach. Where joints are higher up, tell us about the building when you get in touch and we will confirm what’s needed to reach them safely. Common call-outs are for joints with sealant missing in places and moss and dirt in joints with no sealant left, across joints between brick and frames, copings & trims and render & cladding joints.
Somewhere as small as Brook, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Joints on those walls need a sealant that moves with the building and stays in place.
Every job comes with our one-year guarantee.

What we are called out for in Brook
Buildings move more than people expect. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. All of that ends up in the joint sealant.
The most common problems we see are:
- Cracked joints where brick meets render or frames
- Leaking joints around cladding and façade panels
- Hard, crazed mastic that has stopped moving
- Water getting into walls through failed joints
Landford Manor, about 4.1 miles north, is one of the historic houses in the wider area around Brook.

Honest limits
In fairness, some problems need a different trade:
- Rising or penetrating damp from elsewhere in the wall
- Adding movement joints to masonry that has none
- Structural movement, which needs a surveyor or engineer

Brook buildings and the weather
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. Historic houses like Landford Manor (about 4.1 miles north) are a reminder that the area around Brook has older buildings as well as new. Where a home is older, older brick and stone need a sealant that suits them, at the right joint depth.
If you let a flat or house near Ashurst New Forest station, split movement joints are easy to miss on a rental until damp shows inside.

How we quote for external mastic
You will get a clear quote before we start. It’s based on:
- Any working-time requirements on site
- The type of sealant required
- Whether old sealant or filler has to be cut out
- How many areas need sealing
Instead of a standard rate, we price the job in front of us: the amount of work, the old material and the access. You’ll know the price before we begin.
What to tell us for a quote
Before you ask for a quote, have a think about:
- Where the property is
- What the problem is, such as mould, gaps, leaks or cracking
- Roughly how big the job is
- If it’s domestic, commercial or a hotel
Getting a quote is simple: tell us what needs doing and where and its rough size. Photos by email help us understand the job.
For landlords and businesses
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
Mouldy or split sealant often shows up at the end of a tenancy, and it’s quick to put right between tenancies. We can quote for more than one property at once.
How it works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours for a handful of joints, longer for a whole elevation and we leave things clean and tidy. In a small place like Brook, access is normally the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We inspect the joints and agree which need resealing and how they’ll be reached.
- Old sealant and any debris are cut and raked out.
- Both sides are cleaned back to sound material and primed if needed.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Getting ready for the visit
- Let us know if you’ve seen damp or leaks
- On commercial sites, let us know about site rules
- Plan for the work area to be out of bounds to pets and children

What the job involves on each surface
Cladding and façade panels
Metal and composite panels move a lot with temperature, so the joint sealant has to cope with frequent movement. We choose the product to suit.
Copings and trims
Joints in copings, parapets and trims are exposed to the worst of the weather. Each is resealed with a weatherproof, flexible sealant.
