Howe Street External Mastic
Sealing brickwork movement joints, render, cladding and façade joints for homeowners, landlords and businesses in Howe Street. Fully insured, ARBOMaster approved and guaranteed for a year.
- Weeds or debris growing in open joints
- Rigid filler in a joint that should flex
- Weathered mastic that no longer stretches
About our external mastic in Howe Street
External mastic is a job where short cuts show quickly. New sealant over old, joints packed with mortar and beads with no backing rarely last long. We take the old material out and do it properly. If you have movement joints filled with mortar instead of sealant and rain getting behind render or cladding at a joint, we can put it right, on render & cladding joints, façade panels and joints between brick and frames alike.
In a village or hamlet like Howe Street, older cottages and farm buildings often stand in the open, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.
The work is covered for a year after we finish. If there’s a problem with it, please phone 0345 464 0079 or send us an email.

How the job changes by surface
Copings and trims
Coping and trim joints face rain and sun head on. Each is resealed with a weatherproof, flexible sealant.
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. The movement joint takes that up, so the sealant in it must stay soft and stretchy.
Looking after it afterwards
Once the sealant has cured, a few habits help it last:
- Do not let climbing plants root in the sealant
- Check the sealant is paintable before painting near it
- Look over the joints every year, ideally after winter
- Make sure movement joints aren’t pointed over
Give the sealant the cure time we tell you before anything rubs against it. Most exterior sealants skin fast but take longer to cure right through.
Act while the splits are small. Then it’s a straightforward cut-out and reseal.
Leave it or put it right?
Mortar or ordinary filler might look like a quick way to close an open joint, but it locks the joint solid. The movement then cracks the brickwork or render nearby. A flexible sealant over backing rod is what the joint needs. Older cottages and farmhouses around Howe Street can have timber floors and frames, and water through a failed joint can rot timber if it’s left.

How it works
The work is kept neat and contained to the area we are working on, so you can get on with your day. Expect the work to take a few hours to a few days, depending on the length of joint and the access. Somewhere like Howe Street needs a little journey planning: let us know about lanes, gates and parking. Everything for the job comes with us, so a second trip is avoided where possible.
- First we look over the joints with you, agree which to renew and talk through access.
- The old mastic and anything lodged in the joint is removed.
- We clean both faces of the joint and prime them where the product calls for it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- We gun in a flexible exterior sealant in a colour that suits the wall and tool it neatly.
Preparing for the visit
- Where the joints are inside, avoid wetting them before we arrive
- Tell us if parking is tricky
- On commercial sites, let us know about site rules
Getting a quote

Outside joints around Howe Street
The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For an older house near a landmark such as Church of SS Mary and Laurence, an extension built onto an older house moves differently, and the joint between them takes the strain. Rented homes near Beaulieu Park station change hands often, and split movement joints are easy to miss on a rental until damp shows inside.

Your questions about external mastic in Howe Street
Is Howe Street within the area you cover?
Yes, Howe Street is covered. We work across London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you cover Howe Street for external mastic?
Yes, Howe Street is within the area we cover. We work across London and the South East. Just phone 0345 464 0079 or email us with a few details of the job.
Do you work for letting agents?
Yes, we do. Domestic, commercial and hotel work are all part of what we do, and we’re fully insured.
Is it OK to fill a movement joint with cement?
No. Mortar locks the joint solid, so the movement cracks the wall elsewhere. Use a flexible sealant with backing rod.
Why is there a gap in my brick wall?
Walls move with heat, cold and moisture, so long walls have planned gaps to take that movement. It’s closed with backing rod and a flexible sealant.
What information do you need?
Just the basics: where it is, what you’ve noticed and how we reach it. Then phone 0345 464 0079 or send us an email.
Is it OK to seal over old sealant?
No, it won’t last. It can look neat for a few weeks, but the new layer lifts away from the old one. The old sealant has to come out completely.
How do you reach high-level joints?
It depends on the height and the site. Ground-floor joints are simple; for higher ones, send details and we’ll confirm the access.
For landlords and businesses

We also work for property managers and facilities teams. We can quote a run of properties together.
Do you need external mastic in Howe Street?
UV, rain and frost all age exterior sealant. Over the years it hardens, cracks on the surface and loses its give, so the next time the wall moves, it splits or pulls away.
Any of these means the joints need attention:
- Plants rooting in failed movement joints
- Gaps where render, brick and frames meet
- Panel joints letting water in
- Rigid filler in a joint that should flex
Managing a site like Chelmer Valley High School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
