External mastic in Elder Street
Failed sealant is cut out, the depth set with closed-cell backing rod, and the joint resealed with a low-modulus sealant made for outside. We pick a colour that sits well with the wall so the joint does not stand out. Common call-outs are for joints pointed up with cement by mistake and failed sealant between panels on a façade, across concrete & block, brickwork movement joints and copings & trims.
Older homes in small places like Elder Street may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water usually gets in.
Your job is guaranteed for a year, as with all our work.

Looking after it afterwards
How long the joints last depends on use and care. We suggest:
- Check the sealant is paintable before painting near it
- Keep soil, plants and ivy away from the joints
- Keep water from gutters off the wall
- Keep high-pressure jets off the joints
Only paint over the joint if we have confirmed the sealant can take paint. Paint can crack on a flexible joint.
Leave a failed movement joint and water keeps getting into the wall. That can lead to damp patches, staining and frost damage, all bigger jobs than a reseal.
Should I try it myself first?
Too much sealant is as bad as too little. A thick, smeared bead looks untidy and doesn’t move well, and getting the depth right matters as much as the look.
If you’ve already had a go yourself, that’s fine. We remove it and do the joint properly, so just mention it when you contact us.
What affects the quote in Elder Street
Your quote is based on your job. We look at:
- How many areas need sealing
- The number and length of the joints
- Which sealant suits the joint
- Working hours on commercial sites
Doing several joints on one visit usually makes better use of the time than several visits. We’ll give you a clear quote for the lot.
What to tell us for a quote
There’s no need for technical detail. Just tell us:
- If someone has resealed it before
- Access, such as stairs, a lift or height
- How many joints, rooms or windows are involved
- What the problem is, such as mould, gaps, leaks or cracking

Elder Street buildings and the weather
Historic houses like Horham Hall (about 3.5 miles south) are a reminder that the area around Elder Street has older buildings as well as new. In older buildings, older walls and rooflines need a sealant that moves with them and suits the material. Compared with the north and west, the South East gets less rain, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you let a flat or house near Newport (Essex) station, split movement joints are easy to miss on a rental until damp shows inside. Horham Hall, about 3.5 miles south, is one of the historic houses in the wider area around Elder Street.

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 anything from a few hours to several days, depending on the building, depending on the size of the job. Somewhere as small as Elder Street, access is often the only tricky part. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by walking round the building and agreeing the joints and the access.
- We cut out the old mastic and rake out anything in the joint.
- Joint faces are cleaned back and primed if the sealant needs it.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
Getting ready for the visit
- Mention any sign-in or site rules at work premises
- For indoor joints, keep the area dry beforehand if you can
- Let us know if you’ve seen damp or leaks

Advice
How the job changes by surface
Render joints
Render has movement joints and stop beads that need sealing. They’re resealed in a sealant that suits the render.
Concrete and blockwork
Blockwork and concrete shrink over time and move with the seasons. We reseal their joints with backing rod and a flexible product.

Elder Street: your questions answered
Do you work for landlords with property near Newport (Essex) station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just phone 0345 464 0079 or drop us an email with the address and what needs doing, and we’ll send you a clear quote.
Do you cover Elder Street for external mastic?
Yes. Our work covers London and the South East, and Elder Street is part of that. You can call 0345 464 0079 or email us and tell us what needs doing, and we’ll give you a clear price.
Why do you put foam in the joint first?
Backing rod controls the sealant depth and keeps it off the back of the joint. That way it bonds to the two sides only and can stretch.
Is it messy?
Very little: the area around the joints is protected first, and we clear up the old sealant and our materials before we leave.
How do you reach high-level joints?
That depends on the building and the joints. We work on joints that can be reached safely. Give us some details and we’ll confirm the access.
Will the new joint stand out?
There’s a good range of exterior colours, including greys, browns, whites and stone tones. We choose the closest to your brick or render so the joint does not draw the eye.
Are you insured?
Yes. We are fully insured.
Can I do it myself?
Some simple jobs can be done by a careful DIYer. The usual mistakes are sealing over old sealant, sealing a damp joint and using too much.
What happens if it’s left?
Resealing a run of joints in one go is generally better than patching one at a time. They’ve weathered the same way and it means sorting access once. Around Elder Street, older homes often have timber in their floors and frames, where water from a failed joint can cause rot if it’s left.
The cost depends on the amount of work, how much old material has to come out and how easy the joints are to reach. You’ll have a clear quote before any work starts, so you know where you stand.
