How we handle external mastic in Clapton
Ground-floor and low-level joints are straightforward to reach. For joints higher up, give us some details of the building and we will confirm what’s needed to reach them safely. If you’re dealing with rain getting behind render or cladding at a joint and hard, crazed mastic that has stopped moving, we can put it right, on copings & trims, façade panels and joints between brick and frames alike.
Older homes in small places like Clapton may be stone, brick or timber-framed, often with later extensions. Where one material meets another is where water usually gets in.
You’re covered for a year from the day we finish. If there’s a problem with it, please ring 0345 464 0079 or send us an email.

Leave it or put it right?
Sealing over the top of old mastic doesn’t hold for long. New sealant does not bond well to old, weathered sealant, so we always take the old sealant out. In a small place like Clapton, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
We don’t show prices on the website, because each job is priced on what it involves. Call for a quick quote and we’ll talk you through it.

What we do, step by step
Our applicators work methodically: protection first, then preparation, sealing and a tidy-up. Typically it takes a few hours to a few days, depending on the length of joint and the access, and the area is left clean. In a small place like Clapton, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We look at every joint and agree a colour to suit the wall.
- Failed sealant is removed back to clean, sound faces.
- Closed-cell backing rod is pushed in so the sealant bonds to two sides only.
- Primer is applied wherever the sealant needs it.
- A low-modulus exterior sealant is gunned in and tooled to a neat finish.
Preparing for the visit
- For indoor joints, keep the area dry beforehand if you can
- Mention any sign-in or site rules at work premises
- Tell us about any previous sealing or DIY attempts

External mastic in Clapton: local notes
Historic houses like Benham Park (about 3.9 miles south-east) are a reminder that the area around Clapton has older buildings as well as new. Where a home is older, older walls and rooflines need a sealant that moves with them and suits the material. The South East is one of the drier parts of the UK, yet outdoor joints still have to be sealed dry, so jobs are booked with the weather in mind.
For an older house near a landmark such as Church of St Swithin, an extension built onto an older house moves differently, and the joint between them takes the strain. Rented homes near Kintbury station change hands often, and outside joints that have cracked can let damp into a rental, so check them between lets.

What affects the cost of external mastic
Some jobs are bigger than they look, and some smaller. What affects the quote:
- Whether the work is at height
- Any working-time requirements on site
- How many areas need sealing
- The type of sealant required
Rather than a set price list, we price the job in front of us: how many joints, what’s in them now and how we reach them. You’ll know the price before we begin.
Asking for a quote
A few details help us give you an accurate quote. When you get in contact, it helps to mention:
- Whether it has been sealed before
- Roughly how big the job is
- Photos by email, if that is easy
- Whether it’s a home or a business
For a quick quote, get us on the phone, or send an email if you’d rather. Describe what needs sealing and we’ll explain what’s involved and give you a clear quote.
Looking after it afterwards
No joint lasts for ever, but care makes a real difference. A few tips:
- Get split or bare joints resealed while the damage is small
- Keep high-pressure jets off the joints
- Show decorators and builders where the movement joints are
- Walk round the building once a year and look at the joints
Keep pressure washers away from the sealant. High-pressure water can lift the edges.
Act while the splits are small. Then it’s a straightforward cut-out and reseal with no damage behind it to deal with.
Should I try it myself first?
Overfilling a joint is a classic DIY mistake. A thick, smeared bead looks untidy and does not move well, and getting the depth right matters as much as the look.
The difference is mostly in the preparation and the product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions.
Common questions in Clapton
Will you come out to Clapton?
Yes, we do. Our work covers London and the South East, and smaller places are part of that. Longer journeys are simply planned in advance.
Do you cover Clapton for external mastic?
Yes. We work across London and the South East, and Clapton is part of that. You can ring 0345 464 0079 or email us and tell us what needs doing.
What do you need from me for a quote?
The location, the problem and the rough size of the job. Photos by email help too.
What do you put in the joint?
Quality sealants from brands including Arbo and Everbuild, chosen to suit the joint. We explain the product when we quote.
How long will you be here?
Most jobs take a few hours for a handful of joints, longer for a whole elevation, including the preparation. We will confirm how long when we quote.
Can you seal over the old sealant?
No, and we never do. It can look neat for a few weeks, but the new layer lifts away from the old one. Removing the old sealant completely is the only lasting way.
Does someone need to be in?
We need access to the joints, so we will agree that with you when we book. For inside work, that normally means someone being in.
When is the sealant fully cured?
That depends on the sealant used, so follow the cure time we give you when we finish.
How the job changes by surface
Copings and trims
Coping and trim joints face rain and sun head on. We reseal them with an exterior sealant suited to the material.
Render joints
Water behind render can lead to blown patches. A sound joint keeps the render dry behind and helps it last.
For landlords and businesses
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. We have worked in hotels as well as homes and businesses.
Letting agents often deal with us directly. Tell us the address, the job and how access works and we’ll quote.
