About our external mastic in Bassett Green
We cut out failed sealant, set the joint depth with closed-cell backing rod and reseal with a low-modulus exterior sealant. We pick a colour that sits well with the wall. We’re often asked to deal with rigid filler in a joint that should flex and failed seals between different materials, on render & cladding joints, concrete & block and brickwork movement joints.
Houses in smaller places like Bassett Green 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 normally the first to go.
Every job comes with our one-year guarantee.

What sealant work can’t fix
New sealant cannot fix everything, and we’d rather say so up front. Sealant won’t put right:
- Subsidence or other structural problems
- Adding movement joints to masonry that has none
- Rising or penetrating damp from elsewhere in the wall
Not sure which it is? You can call 0345 464 0079 or drop us an email and we will tell you honestly.

Your questions about external mastic in Bassett Green
Can you help a landlord with a rental near Swaythling station?
Yes, we work for landlords and agents. Just ring 0345 464 0079 or drop us an email and tell us about the property, and we’ll send you a clear quote.
Is Bassett Green within the area you cover?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Where are you based?
Our base is Crawley, with over 20 years’ experience. We work across South East England, London and Scotland.
When is the sealant fully cured?
Many sealants skin over quickly but take longer to cure fully. We will tell you how long to leave the joint.
Is there any odour?
Possibly a little. Any smell clears as the sealant cures.
Are you ARBOMaster approved?
Yes. ARBOMaster is the approved applicator scheme for Arbo sealants, and we are part of it.
Will you leave a mess?
Very little: the area around the joints is protected first, and we tidy up before we go.
When will the joints need doing again?
There’s no fixed answer: sunny, exposed elevations and busy joints wear faster. Check them each year and reseal when they split or harden. Our work comes with a one-year guarantee.
How it works
At the end, we look at the finished work together and tell you how long to leave it. The visit itself usually takes a few hours to a few days, depending on the length of joint and the access, depending on the size of the job. In a smaller place like Bassett Green, 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.
- Old sealant and any debris are cut and raked out.
- 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
- Try not to wet indoor joints just before the visit
- Tell us about any water getting in
- Let us know about stairs, lifts or work at height

How the job changes by surface
Cladding and façade panels
Where a cladding system has its own specified sealant, we follow it. Send us any details you have about the façade.
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. That movement goes into the joint, so the sealant in it must stay soft and stretchy.
Walls and rooflines in Bassett Green
Bassett Green is within about 3 miles of the coast, where wind-driven rain is a fact of life and, nearer the shore, so is salt air. Both are hard on movement joints and outside wall joints, which can dry out and crack sooner where a building faces the weather. The South East is one of the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
Rented homes near Swaythling station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets. Homes close to St Alban's Church include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain. For site and facilities teams at buildings such as Bassett Green Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.

DIY versus a professional finish
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.
If you’ve already had a go yourself, that is fine. We cut it out and start again, so just mention it when you contact us.
Keeping the joints in good condition
Once the sealant has cured, a few habits help it last:
- Fix overflowing gutters above sealed joints
- Keep soil, plants and ivy away from the joints
- Act on the first splits you see
- Avoid pressure-washing directly into sealant joints
Have a quick look at the joints each spring. Splits, gaps at the edges or plants in the joint are early warning signs.
Small splits are the time to act. At that stage it’s a simple cut out and reseal with no damage behind it to deal with.
