External mastic in Brookgreen, done properly
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. We pick a colour that sits well with the wall. If you have sealant that has lost its bond to the brick or render and failed seals between different materials, we can put it right, on joints between brick and frames, render & cladding joints and copings & trims alike.
Outside joints can only be sealed when they’re dry, so work in Brookgreen is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
Whatever the size of the job, it’s backed by our 12-month guarantee.

DIY sealant or a professional job?
A careful DIYer can reseal a simple joint, 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.
Too much sealant is as bad as too little. A heavy bead looks messy and copes badly with movement, and the joint depth matters as much as the finish.
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.
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. We reseal their joints with backing rod and a flexible product.
How to look after the new joints
After the cure time, these simple habits help:
- Keep movement joints as flexible joints, not mortar
- Walk round the building once a year and look at the joints
- Leave the joints unpainted unless we’ve said otherwise
- Keep high-pressure jets off the joints
Keep the joints clear of soil, plants and climbing growth. Anything that holds water against the joint wears it out sooner.
An open movement joint lets rain into the wall every time it pours. Over time it can mean damp inside, stained render or frost-damaged brick, all bigger jobs than a reseal.
What happens on the day
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours for a handful of joints, longer for a whole elevation. For a village or hamlet like Brookgreen, the journey is planned in advance: tell us about narrow lanes, gates, long drives and where we can park. Everything for the job comes with us, so a second trip is avoided where possible.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- 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.
How to prepare
- Mention any parking rules near the property
- Move anything stored near the joints
- Plan for the work area to be out of bounds to pets and children

Brookgreen buildings and the weather
Brookgreen is close to the coast, and homes near the sea take more wind-driven rain, with salt in the air closer to the shore. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. Rainfall in the South East is lower than in much of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
If you live in an older home near St. Mary's Church, an extension built onto an older house moves differently, and the joint between them takes the strain.
Brookgreen is about 7 miles south-west of Newport, in the Isle of Wight. Anywhere in PO30, we can carry out external mastic at your property. Our the Isle of Wight coverage runs to 125 places, and Brookgreen is one of them. We also work in Southampton, about 19 miles from Brookgreen.
We work across PO30 for external mastic. We also cover Brook (1 mile north-west), Hulverstone (1 mile north-east), Dunsbury (1 mile north-west), Chilton Green (1 mile east) and Shalcombe (2 miles north).

What we are called out for in Brookgreen
Sometimes a movement joint was filled with mortar or a rigid filler by mistake. The joint cannot move, so the wall cracks somewhere else instead.
Keep an eye out for these signs:
- Cracked joints where brick meets render or frames
- Old sealant gone brittle and cracked
- Sealant that has lost its bond to the brick or render
- Damp patches traced to an open external joint
Around Brookgreen, as everywhere, external mastic is only as good as the preparation behind it.

FAQs for Brookgreen
Can you do external mastic in Brookgreen?
Yes, Brookgreen is within the area we cover. We work across London and the South East. You can ring 0345 464 0079 or drop us an email and tell us what needs doing.
Does living near the coast affect external mastic in Brookgreen?
Coastal homes put outside sealant through more weather than inland ones, so the choice of sealant and the preparation matter even more. It’s worth checking the walls that face the sea first.
Can you quote for more than one area?
Of course. Doing several areas at once is generally more efficient, so mention them when you ask for a quote.
Are you ARBOMaster approved?
Yes. We hold ARBOMaster approved applicator status and we are fully insured too.
What information do you need?
Let us know what needs doing and where, plus pictures if you have them. If we need more, we will ask.
What do you put in the joint?
Each joint gets the product that suits it. Movement, water and weather all affect the choice, and we’ll tell you what we’re using.
Will there be a smell?
There can be a smell while the sealant cures, which fades as it sets. Ventilation helps.
Can you seal joints between render and window frames?
Yes. Materials like render, brick, metal and uPVC all move differently, so a flexible sealant is needed where they meet. We choose one that suits both surfaces.
When it isn’t the sealant
To be straight with you, there are a few things sealant will not fix:
- Render that’s blown, hollow or coming away
- Cracked brickwork or render that needs a builder or plasterer
- Rising or penetrating damp from elsewhere in the wall
If you are not sure, just call 0345 464 0079 or email us and we will give you a straight answer.
