- Failed sealant between panels on a façade
- Damp patches traced to an open external joint
DIY sealant or a professional job?
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is chosen for how the joint moves and where it is, and the work is guaranteed for a year.
Not every job suits DIY: high-level joints, fire-rated gaps, external movement joints and big jobs call for the right materials, safe access and experience.
External mastic for homes and businesses in Crown Wood
Joints in render and cladding are easy to overlook until a damp patch appears. We inspect them, agree which need doing and reseal with a weatherproof, flexible sealant in a matching colour. If you are dealing with weathered mastic that no longer stretches and sealant that has lost its bond to the brick or render, we can put it right, whatever the surface.
Houses in smaller places like Crown Wood 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. Joints on those sides are usually the first to go.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or drop us an email.

Keeping the joints in good condition
Looking after new joints is easy:
- Tell anyone working on the walls about the movement joints
- Don’t let climbing plants root in the sealant
- Fix overflowing gutters above sealed joints
- Wash walls gently around the sealant
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
An open movement joint lets rain into the wall every time it pours. That can lead to damp patches, staining and frost damage.
Crown Wood buildings and the weather
Crown Wood 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 neighbouring houses often have rooflines and wall joints of the same age, wearing out at the same time. Compared with the north and west, the South East gets less rain, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For an older house near a landmark such as St Paul, the joints between older walls, newer extensions and the roofline need a sealant that can move. For site and facilities teams at buildings such as Crown Wood Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. If you let a flat or house near Martins Heron station, failed wall and movement joints let damp in, so they’re worth checking between tenancies.
Crown Wood is about 1 mile south-east of Bracknell, in Bracknell Forest.

What affects the quote in Crown Wood
We quote each job individually. These are the things that affect it:
- How easy the joints are to reach
- How many rooms, windows or areas are involved
- The number and length of the joints
- When we can work, for business premises
We don’t show prices on the website, because the cost depends so much on the job itself. Call for a quick quote.
What to tell us for a quote
To make quoting easier, please include:
- Any previous sealing or DIY work
- Whether it’s a home or a business
- Where the job is, and your postcode
- The rough size of the job
Call for a quick quote, or send an email if you’d rather. Describe what needs sealing and we will talk you through the work.

Crown Wood: your questions answered
Do you cover smaller places like Crown Wood?
Yes. Crown Wood is within the area we cover, which takes in towns, villages and rural addresses. We work across London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is it worth replacing old sealant in an older home in Crown Wood?
Often, yes: cracked, shrunken or mouldy sealant has done its job. New sealant won’t stick to old, so the old bead has to come out completely first.
Can you match the colour of my brickwork?
We aim for a joint that suits the wall rather than one that jumps out. Colour is agreed with you before we begin from the range available.
What do you need from me for a quote?
Only a few details: the address or postcode, what’s wrong and any access issues. Then ring 0345 464 0079 or email us.
Is the work guaranteed?
Yes. Every job comes with a one-year guarantee.
Is it OK to seal over old sealant?
No. Fresh sealant does not stick to old sealant, and anything trapped underneath, including mould and water, stays there. We remove it all first.
Do you do commercial work?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
What is a movement joint?
Brickwork, render and cladding all move a little, so long walls have planned gaps to take that movement. It’s closed with backing rod and a flexible sealant.
Why deal with it now?
Done well, a resealed joint is a neat, straight line that suits the wall. A hurried job with smeared edges and no backing looks worse and fails sooner, so it pays to do it properly once. Homes in smaller places like Crown Wood can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
Homes and businesses are quoted the same way: how much there is to do, how we reach it and what it needs. Call for a quick quote and we’ll go through it with you.

How it works
At the end, we look at the finished work together and tell you how long to leave it. The visit itself normally takes anything from a few hours to several days, depending on the building, depending on how much there is to do. A visit to Crown Wood is planned like any other: the time, the access and where to park are agreed in advance. Outdoor jobs depend on a dry day, since sealant needs a dry surface.
- First we look over the joints with you, agree which to renew and talk through access.
- We cut out the failed sealant and rake out any dirt or growth.
- 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.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
How to prepare
- Clear items away from the joints we are working on
- For business premises, tell us about site rules or sign-in
- Let us know about earlier repairs to the joints

Advice
When something else is needed
Honest advice matters more to us than a booking, so here’s what new sealant will not do:
- Walls that need new movement joints cut into them
- Movement that is more than a sealant joint can take
- Rising or penetrating damp from elsewhere in the wall
If in doubt, ring 0345 464 0079 or email us and we’ll say what we think before you book.
