External mastic for homes and businesses in Stones Green
Short cuts in external joints show up within a season or two. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We strip the joint back and start again. We’re often asked to deal with old sealant gone brittle and cracked and failed seals between different materials, across concrete & block, façade panels and brickwork movement joints.
Somewhere as small as Stones Green, homes and farm buildings often face open ground, where walls and rooflines take the weather head on. Gutter joints and wall joints there need a sealant that can flex and stay put.
Every job is covered by a 12-month guarantee.

The process
We work through the job in order: protection first, then preparation, sealing and a tidy-up. For most jobs that takes a few hours to a few days, depending on the length of joint and the access. Somewhere as small as Stones Green, access is often the only tricky part. If the job is outside, mention outbuildings, exposed walls and how to reach them.
- We start by walking round the building and agreeing the joints and the access.
- 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.
- Backing rod sized to the joint goes in to set the depth.
- The exterior sealant is applied, tooled and checked along its length.
How to prepare
- Mention if the joints have been sealed before
- Let us know if you’ve seen damp or leaks
- Let us know about stairs, lifts or work at height

Why deal with it now?
Mortar or ordinary filler might look like a quick way to close an open joint, but it stops the joint moving. The movement then cracks the brickwork or render nearby. The correct repair is a flexible sealant with the right backing. In a small place like Stones Green, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
There are no prices on our website, because the cost depends so much on the job itself. For a quick quote, please call 0345 464 0079 or drop us an email.

Stones Green questions
Can you help a landlord with a rental near Wrabness station?
Yes, landlords and agents are among the people we work for, and several properties can be quoted together. Just call 0345 464 0079 or send us an email with the address and what needs doing, and we will give you a clear quote.
Is external mastic in a coastal place like Stones Green any different?
Near the sea, outside joints face more wind, rain and salt than they would inland, so preparation and the right sealant matter all the more. It’s worth checking the walls that face the sea first.
How long should I leave it?
That depends on the sealant used, so please follow the time we give you when we finish.
Why is there a gap in my brick wall?
A vertical gap in a long brick wall is normally a movement joint. It lets the bricks expand without cracking.
How long will you be here?
Most jobs take anything from a few hours to several days, depending on the building, including preparation and clearing up. Your quote will say how long we expect yours to take.
What should I tell you?
Where the job is, what the problem is and roughly how big it is. If you can, email a few pictures.
Can you seal joints between two different materials?
Yes. Different materials move at different rates, so a flexible sealant is needed where they meet. We choose one that suits both surfaces.
Is it worth trying it myself?
It depends on the job. Work at height, movement joints, fire-rated gaps and large areas are best left to a professional, while a short indoor joint may be within reach.
What affects the cost of external mastic
For a quick quote, just ask. The main things that affect it are:
- The size of the job
- How much old sealant there is and how hard it is to remove
- Access and height
- Any working-time requirements on site
Some things make a job bigger or smaller: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether the work is at height. We take all of that into account in your quote.
Asking for a quote
Before you ask for a quote, have a think about:
- A few photos by email, if you can
- Any access issues, like height or stairs
- How many joints, rooms or windows are involved
- If someone has resealed it before
Call for a quick quote, or email us if that’s easier. Describe what needs sealing and we will talk you through the work.
Should I try it myself first?
If you are set on DIY, put the effort into preparation: take out all the old sealant, make sure the joint is clean and dry, and give it the full cure time. If it doesn’t work out, we can still put it right.
What a professional job adds is preparation and the right product. We take joints back to clean, dry surfaces, and the sealant is matched to the joint and its conditions, then guaranteed for a year.
External mastic in Stones Green: local notes
Stones Green is within about 3 miles of 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. London and the South East are among the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
Managing a site like Wix and Wrabness Primary School? Then movement joints, cladding joints and gutters on larger buildings need the same care as a house’s. Thorpe Hall, about 3.3 miles south, is one of the historic houses in the wider area around Stones Green, and older homes nearby need a sealant that suits their walls. Letting a property close to Wrabness station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Work for landlords, hotels and businesses
In hotels, rooms out of use cost money, so we plan the work room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Landlords and agents in Stones Green can book us as well as homeowners. Resealing between tenancies keeps a property looking cared for before the next move-in.
Keeping the joints in good condition
Joint life depends on how it’s used and looked after. Here’s what we suggest:
- Fix overflowing gutters above sealed joints
- Point out the joints to other trades
- Check the sealant is paintable before painting near it
- Get split or bare joints resealed while the damage is small
Keep pressure washers away from the sealant. A strong jet can damage the edges of the bead and let water in behind.
If you can see gaps, plants or bare sections in a joint, have it checked. Early work is quicker and leaves a better finish.
