What to tell us for a quote
When you contact us, it’s useful to know:

- Photos by email, if that is easy
A good description makes for an accurate quote. Let us know the location, the problem and roughly how many joints.
How we handle external mastic in Preston Bissett
On houses, flats and commercial buildings across Preston Bissett, we reseal joints in brickwork, render, cladding and façade panels. Every joint gets the same careful preparation: clean joint faces and the right depth. Common call-outs are for sealant pulling away from one side of the joint and damp patches traced to an open external joint, across copings & trims, façade panels and brickwork movement joints.
In a village or hamlet like Preston Bissett, older cottages and farm buildings often stand in the open, so walls and rooflines take the full force of wind and rain. Gutter joints and wall joints there need a sealant that can flex and stay put.
There’s a 12-month guarantee on every job.

Advice
Honest limits
We won’t take on work that will not last, so these are the limits:
- Walls that need new movement joints cut into them
- Loose or hollow render, which needs re-rendering
- Cracking across the wall rather than at a joint
Not sure which it is? You can ring 0345 464 0079 or send us an email and we’ll tell you honestly before booking.
What we seal
- Joints between brick and frames
- Concrete & block
- Render & cladding joints
- Brickwork movement joints
- Façade panels
- Copings & trims
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 doesn’t work out, we can still put it right.
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.
Leave it or put it right?
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. In a small place like Preston Bissett, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
What you pay reflects the work, not guesswork. That’s why we ask a few questions first and give you a clear quote before any work starts.

Common questions in Preston Bissett
Can you do external mastic in Preston Bissett?
Yes, Preston Bissett is within the area we cover. We work across London and the South East. Just call 0345 464 0079 or send us an email with a few details of the job, and we will give you a clear quote.
Is there a guarantee on external mastic in Preston Bissett?
All our work, in Preston Bissett and everywhere else, comes with a 12-month guarantee. We’re fully insured, and an ARBOMaster approved applicator.
Do you take out the old sealant first?
Always. Sealing over old sealant is the main reason resealing fails early, and it’s something we never do.
Where are you based?
Our base is in Crawley, West Sussex, and we cover South East England, London and all of Scotland.
Do I need to be at home?
Access is agreed with you when the job is booked. For inside work, that normally means someone being in.
What do you put in the joint?
Products from Arbo and Everbuild, among others, picked for each joint. We’ll tell you what we are using and why.
Is there any odour?
There can be a smell while the sealant cures, which fades as it sets. Opening a window helps.
What information do you need?
The location, the problem and the rough size of the job. If you can, email a few photos.
How to look after the new joints
A little care helps the new joints last. We recommend:
- Make sure movement joints aren’t pointed over
- Avoid pressure-washing directly into sealant joints
- Act on the first splits you see
- Walk round the building once a year and look at the joints
Only paint over the joint if we have confirmed the sealant can take paint. Paint can crack on a flexible joint, and paint can crack as the joint moves.
Once a joint can’t move, the wall finds another way, often as cracks near the joint. Catch it early and you reduce the risk.
Outside joints around Preston Bissett
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. With historic houses such as Claydon House (about 4.7 miles south-east) nearby, there’s older building stock in the area around Preston Bissett as well as newer homes. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
Around Preston Bissett, as everywhere, external mastic is only as good as the preparation behind it.

What we’re called out for in Preston Bissett
The wrong product in a moving joint is a classic cause. A high-modulus or general-purpose sealant can be too rigid for a busy joint, and it tears off the sides.
Keep an eye out for any of the following:
- Cracked joints where brick meets render or frames
- Movement joints with cracked, split or missing sealant
- Rigid filler in a joint that should flex
- Leaking joints around cladding and façade panels
If you live in an older home near Church of St John the Baptist, an extension built onto an older house moves differently, and the joint between them takes the strain.
Questions to ask before booking
- What the cure time is
- What product goes in the joint
- How the colour is chosen
- Whether they seal over old material or remove it
