Bulphan External Mastic

External mastic in Bulphan, done properly
Ground-floor and low-level joints are straightforward to reach. For joints higher up, give us some details of the building and we’ll confirm what access is needed. We work on joints between brick and frames, copings & trims and concrete & block, and the jobs we see most are water getting into walls through failed joints and movement joints filled with mortar instead of sealant.
Outside work in London starts with access: side passages, upper floors and where to park. For a home in Bulphan, tell us how high the joints are and how to reach the back of the building.
Our work is backed for twelve months.

How the visit works
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes anything from a few hours to several days, depending on the building and we leave things clean and tidy. Many London jobs are in flats, so we come ready for stairs, narrow hallways and shared entrances. Mention any building rules, key holders or managing agents when you book.
- First, the joints are inspected and the access agreed.
- Every bit of old sealant and any mortar or debris is cut out.
- The faces are brushed clean and primed where the product requires it.
- We fit closed-cell backing rod to control the depth.
- The exterior sealant is applied, tooled and checked along its length.
Before we arrive
- Mention any leaks or damp you’ve noticed
- Mention any tricky access
- Tell us about any previous sealing or DIY attempts

Advice
Why it’s worth doing now in Bulphan
The longer a joint stays open, the more water the wall takes in. In cold weather, frost can damage wet brick and render around the joint, so the damage spreads beyond the joint. In London conversions, one flat’s bathroom is often above another flat’s ceiling, and a slow leak from a failed seal can end up in the flat below. Dealing with it early is far simpler for homes in Bulphan.
No two jobs are quite the same, so we quote each one individually. The number of joints, how easy they are to reach and the sealant needed all play a part, and we will explain the quote if you ask.
Why book with us
- A choice of colours where the product allows
- Neat joints and a tidy finish
- Sanitary silicone with an anti-fungal additive in wet areas
- We’re fully insured

Aftercare tips
So the new joints stay in good condition:
- Have failed joints looked at early
- Deal with leaking gutters that soak the joints below
- Tell anyone working on the walls about the movement joints
- Leave the joints unpainted unless we have said otherwise
Give the sealant the cure time we tell you before anything rubs against it. The surface skins over quickly, but full cure takes longer.
Small splits are the time to act. Then it’s a straightforward cut-out and reseal before water has had years to get in.
Do you need external mastic in Bulphan?
Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.
Common reasons people contact us are:
- Sealant pulling away from one side of the joint
- Gaps where render, brick and frames meet
- Joints with sealant missing in places
- Old sealant gone brittle and cracked
As a London address, Bulphan can be tricky for parking: tell us about permits, visitor bays or off-street space when you book.
Before you book anyone
- Which sealant they’ll use, and why
- What the cure time is
- The length of the guarantee
- What happens if they find a problem under the old sealant
Bulphan buildings and the weather
London terraces and converted houses often share gutters, downpipes and walls, so check who is responsible for the outside before booking. 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 landlords with property near West Horndon station, failed wall and movement joints let damp in, so they’re worth checking between tenancies. Homes close to Church of St Mary include some older properties, and older walls, gutters and the joints where extensions meet them need a flexible sealant.

When something else is needed
We’d rather tell you now than do work that won’t last, so here’s what sealant can’t put right:
- Cutting new joints into brickwork, which is building work rather than sealant work
- Subsidence or other structural problems
- Cracked brickwork or render that needs a builder or plasterer

DIY sealant or a professional job?
If you’ve already had a go yourself, that is fine. We remove it and do the joint properly.
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 does not work out, we can still put it right.

Common questions in Bulphan
I let a flat near West Horndon station. Can you help?
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 will give you a clear quote.
Is Bulphan in your area for external mastic?
Yes. We work across London and the South East, and Bulphan is part of that. Just call 0345 464 0079 or email us with a few details of the job, and we will give you a clear price.
Will it make a mess?
Tidy work is part of the job. We protect what’s around the joints, and we clear up when we are done.
Why is there a gap in my brick wall?
Walls move with heat, cold and moisture, and planned joints take up that movement. The gap is sealed with a flexible sealant over backing rod.
Are you ARBOMaster approved?
Yes. We are an ARBOMaster approved applicator, the approved applicator scheme for Arbo sealants.
Do you do commercial work?
Yes. We’ve worked for hotels, offices and other businesses, and we are fully insured.
Do you use backing rod?
That’s backing rod, a closed-cell foam. It stops the sealant going in too deep and bonding to three sides so it can flex with the joint.
Do you have insurance?
Yes. We’re fully insured for domestic and commercial work.
