Low Street External Mastic
Problem with your movement joints in Low Street? We remove the old material, prepare the joints and seal them properly, and the work is guaranteed for a year.
- Water getting into walls through failed joints
- Rigid filler in a joint that should flex
- Moss and dirt in joints with no sealant left
Common problems we fix in Low Street
Poor preparation causes many early failures: dusty or wet faces, no primer where one was needed, or old sealant left in. The new sealant then lets go long before it should.
The problems people normally mention when they call are:
- Sealant that has lost its bond to the brick or render
- Failed sealant between panels on a façade
- Gaps where render, brick and frames meet
- Joints with sealant missing in places
In the older streets around St James' Church, old and new materials meet at the roofline and walls, which is where sealant earns its keep.

External mastic for homes and businesses in Low Street
As ARBOMaster approved applicators, we choose exterior sealants to suit the joint and the surfaces. Some surfaces need a primer before sealing, and we do not skip that step. We’re often asked to deal with hard, crazed mastic that has stopped moving and movement joints with cracked, split or missing sealant, on copings & trims, façade panels and brickwork movement joints.
Older homes in small places like Low Street may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water generally gets in.
Each job carries a 12-month guarantee.

Work for landlords, hotels and businesses
In hotels, rooms out of use cost money, so the work can be planned room by room. We have worked in hotels as well as homes and businesses.
Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.
What happens on the day
We keep the work tidy and contained to the area we’re working on. The job generally takes a few hours for a handful of joints, longer for a whole elevation, and we explain the cure time before we leave. In a small place like Low Street, access is generally the main thing to plan. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We look at every joint and agree a colour to suit the wall.
- 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
- Where the joints are inside, avoid wetting them before we arrive
- Let us know about earlier repairs to the joints
- Tell us about access, such as stairs, a lift or high-level joints

Related advice
Low Street: your questions answered
I let a flat near East Tilbury station. Can you help?
Yes, landlords and agents are among the people we work for. Just call 0345 464 0079 or email us with the address and what needs doing, and we will send you a clear quote.
Is external mastic in a coastal place like Low Street any different?
Coastal weather is harder on outside sealant: there’s more wind-driven rain and, closer to the shore, salt in the air. The right product, a clean joint and the right depth all help it cope.
Will you leave a mess?
We keep the work tidy. We protect what’s around the joints.
Should I point up the gap in my brickwork?
No, not if it’s a movement joint. Pointing it stops it working. We’ll reseal it with a flexible sealant.
Do you do commercial work?
Yes, regularly. We can plan bigger jobs in stages to suit the site.
How do you reach high-level joints?
That depends on how high the joints are and the ground below. Low-level joints are straightforward; for higher work, tell us about the building and we’ll confirm what’s needed.
When is the sealant fully cured?
Most sealants are touch-dry well before they’re fully cured. We will give you the cure time for the product we used before we leave.
Where do you work from?
Mr Mastic is based in Crawley. Our applicators cover Low Street, along with the rest of our area.
What external mastic looks like in Low Street
Low Street is close to 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.
Managing a site like East Tilbury Primary School? Then 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 East Tilbury station, split movement joints are easy to miss on a rental until damp shows inside.

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 doesn’t work out, we can still put it right.
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and the joint depth matters as much as the finish.
Why deal with it now?
It often makes sense to reseal all the failing joints on an elevation together. They’ve weathered the same way and it means sorting access once. Where a wall is exposed, as many are in small places like Low Street, wind-driven rain gets into any failed joint, and older walls, once damp, take a long time to dry.
