About our external mastic in Brockenhurst
Joints between dissimilar materials, like brick against render or concrete against a steel frame, see movement from both sides. A flexible exterior sealant takes up that movement where a rigid filler would soon crack. Typical jobs include rigid filler in a joint that should flex and brick movement joints where the sealant has split, across façade panels, render & cladding joints and concrete & block.
Around Brockenhurst, garages, outbuildings and extensions all add to the joints on the outside of a home. Leaks usually start at a gutter end, a garage door frame or where an extension meets the house.
The work is covered for a year after we finish. If there’s a problem with it, please call 0345 464 0079 or email us.

Looking after it afterwards
How long the joints last depends on use and care. Here’s what we suggest:
- Avoid pressure-washing directly into sealant joints
- Make sure movement joints are not pointed over
- Ask before painting over external sealant
- Walk round the building once a year and look at the joints
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
Water getting behind cladding or render can go unnoticed for a long time. When it finally shows inside, the joint may have been open for years, so it’s worth resealing at the first signs.
Brockenhurst questions
Do you cover Brockenhurst for external mastic?
Yes, Brockenhurst is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or email us and tell us what needs doing, and we’ll send you a clear quote.
I let a flat near Brockenhurst station. Can you help?
Yes, rental work is part of what we do. You can ring 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before any work starts.
Can you reach joints on upper floors?
It depends on the building. Tell us the height, the number of joints and what’s below them and we will confirm how they can be reached safely.
Can you seal over the old sealant?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Are you an approved applicator?
Yes. We are ARBOMaster approved, the scheme for applicators of Arbo sealants.
Can you seal joints between render and window frames?
Yes. Joints between dissimilar materials are a big part of external work. The sealant is chosen to bond to both sides, primed where needed.

Yes. Hotels, offices and other businesses use us and we are fully insured.
Where do you work from?
Mr Mastic is based in Crawley. We cover Brockenhurst and the rest of Hampshire, along with the rest of our area.

How the visit works
We bring everything the job needs with us. After a quick look at the joints together, we protect the area and start. Most jobs take anything from a few hours to several days, depending on the building.

- We start by walking round the building and agreeing the joints and the access.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.

Advice
External mastic in Brockenhurst: local notes
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.
Rented homes near Brockenhurst station change hands often, and split movement joints are easy to miss on a rental until damp shows inside. In the older streets around Church of St Saviour, an extension built onto an older house moves differently, and the joint between them takes the strain. Schools such as Brockenhurst Church of England Primary School are buildings too, and its movement joints, gutters and trims need looking after like any other building’s.

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?
A DIY attempt doesn’t rule out a professional job. We cut it out and start again, so tell us about it when you ask for a quote.
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.
Why deal with it now?
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That matters on brick, render and concrete, which can be weaker at the face. A stiffer product can damage the joint edge as it fails. Around Brockenhurst, water from a failed joint in an older home can soak into timber and plaster, which is far harder to put right than the sealant itself.
Commercial jobs are quoted on the same basis as homes: the amount of work, how we reach it and what it needs, along with when we can work on site. Call for a quick quote and we will explain what it covers.
