External mastic in Priestwood
Joints in render and cladding are easy to overlook until a damp patch appears. We look over the joints, agree the ones to renew and reseal with a flexible, weatherproof product in a colour to suit. We work on concrete & block, façade panels and brickwork movement joints, and people most often call us about rigid filler in a joint that should flex and panel joints letting water in.
Houses in smaller places like Priestwood can stand more in the open than those in a built-up town, and walls and rooflines facing the weather take the worst of it. That’s where gutter joints and wall joints tend to fail first.
All of our work is guaranteed for twelve months.

What the job involves on each surface
Joints between dissimilar materials
Each side of the joint may need its own preparation. Both surfaces are cleaned and primed as the product requires.
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.
Looking after it afterwards
Good habits help new joints last longer. A few tips:
- Have failed joints looked at early
- Walk round the building once a year and look at the joints
- Avoid pressure-washing directly into sealant joints
- Check the sealant is paintable before painting near it
Only paint over the joint if we’ve confirmed the sealant can take paint. Many exterior sealants are not designed to be painted and spoil the finish.
If you can see gaps, plants or bare sections in a joint, have it checked. Earlier resealing means a smaller job and a better result.
Priestwood questions
Do you cover smaller places like Priestwood?
Yes, we do. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
I let a flat near Bracknell station. Can you help?
Yes, rental work is part of what we do. You can call 0345 464 0079 or send us an email with the address and a few details, and we’ll give you a fixed price before any work starts.
Should I try DIY first?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
Where is Mr Mastic based?
We are a Crawley-based firm, with over 20 years’ experience. We work across South East England, London and Scotland.
Do you use backing rod?
That is backing rod, a closed-cell foam. It keeps the sealant at the right depth and bonded to the sides only so it can flex with the joint.
Are you fully insured?
Yes. Mr Mastic is fully insured.
What is a movement joint?
A movement joint is a planned break in the wall that absorbs expansion and shrinkage. It’s sealed with a flexible sealant, not mortar.

External mastic in Priestwood: local notes
Priestwood is part of Bracknell, one of the post-war new towns. Homes here were built in phases, many of them in the post-war decades, so whole streets can have gutters, trims and wall joints reaching the end of their life together. 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.
If you look after a building such as Meadow Vale Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Homes close to St Andrew include some older properties, and old and new materials meet at the roofline and walls, which is where sealant earns its keep.
Priestwood is about 1 mile north-west of Bracknell, in Bracknell Forest. Priestwood gets the same service as everywhere we cover: the old material taken out, joints prepared properly and a 12-month guarantee.

Quotes for external mastic in Priestwood

- The product the joint needs
- The number of rooms or windows
- The number and length of the joints
A few things move the cost up or down: the old material and how easily it comes out, any mould to treat, and whether we need extra access for height. Your quote takes all of that into account.

Why it’s worth doing now in Priestwood
Running new sealant over the old bead rarely lasts. The new layer can’t bond properly to old, weathered material, so the old joint is cut out fully first. Homes in smaller places like Priestwood can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
The cost reflects the work involved, not a rough estimate. That is why we ask about the job first and agree the price before starting.

Common problems we fix in Priestwood
Sunlight, wet weather and frost wear exterior sealant down. In time it goes hard, crazes on the surface and stops stretching, so the next time the wall moves, it splits or pulls away.
Look out for any of the following:
- Gaps where render, brick and frames meet
- Moss and dirt in joints with no sealant left
- Hard, crazed mastic that has stopped moving
- Sealant that has lost its bond to the brick or render
Letting a property close to Bracknell station? Then outside joints that have cracked can let damp into a rental, so check them between lets.

Landlord and commercial work in Priestwood
From a single let to a portfolio, the work is the same standard: old sealant fully removed, joints prepared properly and a one-year guarantee.
Water getting past a failed joint can damage the building, which matters even more when someone else lives there. Resealing at the right time is simple maintenance that we can handle for you.
How it works
Good joint work is mostly preparation, so that is where we spend the time. Joints are cleaned back and dried before anything new goes in. All told, the work takes a few hours to a few days, depending on the length of joint and the access. In a smaller place like Priestwood, parking is seldom the issue; lanes, gates and long drives are worth mentioning. For outside work, side access and the height of the joints help us plan.
- First we look over the joints with you, agree which to renew and talk through access.
- The old mastic and anything lodged in the joint is removed.
- The joint faces are cleaned and primed where the sealant needs it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Preparing for the visit
- Tell us if parking is tricky
- Tell us about access, such as stairs, a lift or high-level joints
- Clear the area around the work
