What happens on the day
All our tools and materials come with us in the van, so you don’t need to buy or prepare anything. 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.

How we handle external mastic in Brooks Green
External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We take the old material out and do it properly. We work on brickwork movement joints, copings & trims and concrete & block, and the jobs we see most are hard, crazed mastic that has stopped moving and brick movement joints where the sealant has split.
Older homes in small places like Brooks Green may be stone, brick or timber-framed, often with later extensions. The joints where those materials meet are the weak points, and they need the right sealant at the right depth.
All of our work is guaranteed for twelve months, in Brooks Green and everywhere else we cover.

Outside joints around Brooks Green

What sealant work can’t fix
We’d rather tell you now than do work that won’t last, so here’s what sealant can’t put right:
- Adding movement joints to masonry that has none
- Render that is blown, hollow or coming away
- Structural movement, which needs a surveyor or engineer
If you’re not sure, just call 0345 464 0079 or send us an email and we’ll give you a straight answer.
Where we work in Brooks Green
- Concrete & block
- Brickwork movement joints
- Façade panels
- Joints between brick and frames
- Render & cladding joints
- Copings & trims
Should I try it myself first?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly, so tell us about it when you ask for a quote.

What affects the quote in Brooks Green
Jobs vary more than people expect. What affects the quote:
- Whether old sealant or filler has to be cut out
- Any mould that needs treating
- Which sealant suits the joint
- Any working-time requirements on site
No two jobs are quite the same, so each one gets its own quote. The number of joints, how easy they are to reach and the sealant needed all play a part.
What to tell us for a quote
There’s no need for technical detail. Just tell us:
- Where the job is, and your postcode
- Any access issues, like height or stairs
- What the problem is, such as mould, gaps, leaks or cracking
- Roughly how big the job is
For a quick quote, get us on the phone, or email us if that’s easier. Describe what needs sealing and we’ll explain what’s involved and send you a clear quote.
Keeping the joints in good condition
Aftercare is simple, and it makes a real difference:
- Wash walls gently around the sealant
- Walk round the building once a year and look at the joints
- Make sure movement joints are not pointed over
- Keep water from gutters off the wall
If you have more work done on the wall, such as new render, cladding or an opening, show the contractor the movement joints. They should be kept open and resealed, not filled.
A joint that has stopped moving pushes the movement elsewhere, normally as cracking in the brickwork or render nearby. Resealing it early helps prevent that.

Different surfaces, different methods
Brickwork movement joints
Brick walls have vertical movement joints to absorb expansion. They’re resealed over backing rod with a low-modulus sealant in a colour to suit the brick.
Render joints
Water behind render can lead to blown patches. Resealing the joints early keeps water out and helps it last.
Why act early in Brooks Green
An open joint keeps letting water into the wall with every downpour. Wet masonry is more easily damaged by frost around the joint, so the problem grows beyond the joint itself. Older cottages and farmhouses around Brooks Green can have timber floors and frames, where water from a failed joint can cause rot if it’s left.
A failed joint rarely gets cheaper to fix by waiting, as water and mould keep getting in. If you are unsure, ring 0345 464 0079 or email us for an honest opinion and a quote.
