DIY sealant or a professional job?
If you’re set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it fails, we can still redo it.
Some sealant jobs are within reach of a careful DIYer, such as a straightforward joint indoors. Where it goes wrong is sealing over the old bead, working on a wet joint or overloading the gap.
How we handle external mastic in Brook
On houses, flats and commercial buildings across Brook, we reseal joints in brickwork, render, cladding and façade panels. The preparation is the same whatever the wall: clean joint faces and the right depth. We work on joints between brick and frames, render & cladding joints and façade panels, and common reasons people get in touch are joints where the bead has come unstuck and movement joints with cracked, split or missing sealant.
External sealant needs dry, clean surfaces, so work around Brook is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
Big or small, you get the same 12-month guarantee.

Questions from Brook
Can you help a landlord with a rental near Witley station?
Yes, we work for landlords and letting agents. Just call 0345 464 0079 or send us an email and tell us about the property, and we will give you a clear quote.
Do you cover Brook for external mastic?
Yes. Our work covers London and the South East, and Brook is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job.
Is there any odour?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
Will you leave a mess?
Tidy work is part of the job. We protect what’s around the joints, and the area is left clean when we finish.
Do you guarantee your work?
Yes, always. Each job is guaranteed for twelve months, large or small.
Can you seal joints between render and window frames?
Yes. We cut out the old sealant, prepare both faces and reseal with a flexible exterior product. We pick a colour that works with both materials.
Can you quote for more than one area?
Yes. Tell us about everything you’d like done and we’ll quote it together.
How long should I leave it?
It depends on the product and the conditions. Before we leave, we will tell you the cure time.
What happens on the day
The work is kept neat and contained to the joints we’re treating, so you can carry on as normal. Expect the work to take anything from a few hours to several days, depending on the building, and we explain the cure time before we leave. In a small place like Brook, access is normally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- 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.
- We apply the sealant, tool it and check the whole run.
Preparing for the visit
- Mention if the joints have been sealed before
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about parking restrictions

How to look after the new joints
Good habits help new joints last longer. A few tips:
- Check the sealant is paintable before painting near it
- Clear growth from the base of walls and joints
- Show decorators and builders where the movement joints are
- Keep water from gutters off the wall
Give the sealant the cure time we tell you before anything rubs against it. Most exterior sealants skin fast but take longer to cure right through.
Act while the splits are small. Then it’s a straightforward cut-out and reseal with no damage behind it to deal with.
Why act early in Brook
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. Older cottages and farmhouses around Brook can have timber floors and frames, and water through a failed joint can rot timber if it’s left.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, along with when we can work on site. Ask us for a quote and we’ll explain what it covers.

When something else is needed
We’ll always be straight with you, so here’s what new sealant won’t do:
- Rising or penetrating damp from elsewhere in the wall
- Subsidence or other structural problems
- Adding movement joints to masonry that has none
If you are not sure, just ring 0345 464 0079 or drop us an email and we’ll give you a straight answer.

Signs you need external mastic in Brook
Weeds, moss and debris in a joint are a sign the sealant has gone. Roots and dirt hold water against the wall and speed up the damage.
Most people get in touch after spotting something like this:
- Rain getting behind render or cladding at a joint
- Moss and dirt in joints with no sealant left
- Panel joints letting water in
- Rigid filler in a joint that should flex
Schools such as King Edward's School Witley are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
Questions to ask before you book
- Whether they seal over old material or remove it
- The length of the guarantee
- What happens if they find a problem under the old sealant
- Whether they’re fully insured
