External Mastic in Broadley Common
External mastic for Broadley Common and the surrounding area: careful preparation, the right product and tidy work. Call for a quick quote.
- Failed sealant between panels on a façade
- Old sealant gone brittle and cracked
- Sealant that has lost its bond to the brick or render
Should I try it myself first?
If you do try it yourself, take your time over the preparation: remove every trace of old sealant, clean and dry the joint, and follow the product’s cure time. If it fails, we can still redo it.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
External mastic in Broadley Common, done properly
Low-level joints can usually be done from the ground. For joints higher up, give us some details of the building and we’ll confirm what access is needed. If you have failed sealant between panels on a façade and joints with sealant missing in places, we can put it right, whatever the surface.
External sealant needs dry, clean surfaces, so work around Broadley Common is planned for dry weather. Tell us about access to all sides of the building, including outbuildings and garages.
All of our work is guaranteed for twelve months, and the guarantee is the same wherever you are.

How the job changes by surface
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. The old joint is removed and a sealant that bonds to both sides goes in.
Render joints
Render is weaker at the surface than brick, so a low-modulus sealant is kinder to the joint edges. Priming is done where the sealant calls for it.
Your questions about external mastic in Broadley Common

Yes. We work across London and the South East, and Broadley Common is part of that. You can phone 0345 464 0079 or drop us an email and tell us what needs doing, and we will give you a clear price.

Do you do commercial work?
Yes. Hotels, offices and other businesses use us, and we are fully insured.
What sealant do you use?
The product depends on the job: anti-fungal sanitary silicone in wet areas, and other sealants where joints move or face the weather. We use products from Arbo and Everbuild.
How long before the joint can be used?
It depends on the product and the temperature. Before we leave, we’ll tell you the cure time.
How long does external mastic last?
That varies with the weather the wall faces, how much it moves and the sealant used. Treat it as a maintenance item and look at it yearly and reseal when it splits.
Can you match the colour of my brickwork?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We pick the one that suits your wall best so the joint does not draw the eye.
Where is Mr Mastic based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.

How it works
Once we’re on site, we check the joints match what you told us. If we find something unexpected, we talk it through with you first. After that, the work takes a few hours to a few days, depending on the length of joint and the access. For a village or hamlet like Broadley Common, 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.
- Each joint is checked and the colour of the new sealant agreed.
- We take out the old sealant until the faces are sound.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- We prime the faces where required.
- We gun in low-modulus sealant and tool it neatly.
Before we arrive
- Mention if the joints have been sealed before
- Try not to wet indoor joints just before the visit
- Clear the area around the work
How to get a quote
Asking for a quote is easy: let us know the job and the location, and roughly how big it is. Photos by email help us understand the job.

Common problems we fix in Broadley Common
Using the wrong sealant is another common reason. A high-modulus or general-purpose sealant can be too rigid for a busy joint, and it tears off the sides.
Most people get in touch after spotting one of these:
- Sealant that has lost its bond to the brick or render
- Weathered mastic that no longer stretches
- Water getting into walls through failed joints
- Moss and dirt in joints with no sealant left
Schools such as Water Lane Primary Academy are buildings too, and movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
What to look for in a quote
- How hidden problems are handled
- What the quote includes, VAT included or not
- Whether all the old sealant comes out first
- How much experience the applicator has
When something else is needed
A few problems are outside what sealant work can do:
- Walls that need new movement joints cut into them
- Cracking across the wall rather than at a joint
- Render that’s blown, hollow or coming away
If you are not sure, just phone 0345 464 0079 or drop us an email and we will give you a straight answer.
