What the job involves on each surface
Brickwork movement joints
Brick moves with heat and moisture, and grows a little over time. The movement joint takes that up, so its sealant has to stay flexible.
Joints between dissimilar materials
Where a frame or panel meets masonry, water often finds a way in. The old joint is removed and a sealant that bonds to both sides goes in.
About our external mastic in Darland
External mastic is a job where short cuts show quickly. Overfilled joints, missing backing rod and sealant laid over old sealant rarely last long. We strip the joint back and start again. If you are dealing with sealant pulling away from one side of the joint and movement joints with cracked, split or missing sealant, we can help, on brickwork movement joints, façade panels and concrete & block alike.
Outside joints can only be sealed when they’re dry, so work in Darland is booked around the forecast. Let us know about access to every wall, plus any garages or outbuildings.
The work is covered for a year after we finish. If anything is not right with it, ring 0345 464 0079 or send us an email.

How the visit works
The work is kept neat and contained to the area we’re working on, so you can carry on as normal. Expect the work to take anything from a few hours to several days, depending on the building, and we explain the cure time before we leave. In a small place like Darland, access is usually the main thing to plan. For outside work, also let us know about exposed walls and any outbuildings involved.
- We start by checking each joint, agreeing the ones to redo and how we will reach them.
- Old sealant and any debris are cut and raked out.
- The joint faces are cleaned and primed where the sealant needs it.
- Backing rod goes in next, setting the depth and keeping the sealant off the back of the joint.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Before we arrive
- Mention any sign-in or site rules at work premises
- Let us know about earlier repairs to the joints
- Move anything stored near the joints

Advice
External mastic in Darland: local notes
Darland 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. That is hard on movement joints and outside wall joints, especially on the side facing the sea. Historic houses like Restoration House (about 2.8 miles north-west) are a reminder that the area around Darland 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.
For an older house near a landmark such as Christ Church, an extension built onto an older house moves differently, and the joint between them takes the strain. Letting a property close to Gillingham (Kent) station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.
Darland is about 1 mile south-west of Gillingham, in Medway. Homes, rented property, offices and hotels in Darland is covered for external mastic. The work is guaranteed for a year.

Why it’s worth doing now in Darland
A low-modulus sealant is chosen because it moves without pulling hard at the edges. That protects surfaces like brick, render and concrete. Too stiff a sealant can pull at the edges and break them. Where a wall is exposed, as many are in small places like Darland, wind-driven rain gets into any failed joint, and damp in older walls is slow to dry out.
There are no prices on our website, because each job is priced on what it involves. Call for a quick quote and we will talk you through it.

Do you need external mastic in Darland?
A lot of failed joints come down to preparation: dusty or wet faces, no primer where one was needed, or old sealant left in. The sealant never bonds properly.
Keep an eye out for these signs:
- Old sealant gone brittle and cracked
- Failed seals between different materials
- Sealant that has lost its bond to the brick or render
- Movement joints with cracked, split or missing sealant
Managing a site like Kingfisher Community Primary School? Then its movement joints, gutters and trims need looking after like any other building’s.

FAQs for Darland
Will you come out to Darland?
Yes, smaller places are covered as well as towns. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Is external mastic in a coastal place like Darland any different?
Near the coast, wind-driven rain and, nearer the shore, salt air make outside sealant work harder. Choosing the right sealant for the frame and wall, laid at the right depth, helps it last.
Should I try DIY first?
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.
Can you do several jobs on one visit?
Yes. Just list everything you need and we’ll quote it together.
Which products do you use?
We choose the sealant for the joint, not the other way round. Movement, water and weather all affect the choice, and we will explain our choice.
How often do external joints need resealing?
There’s no fixed answer: joints on exposed walls or with a lot of movement age sooner. A yearly look will tell you when they need doing. Our work comes with a one-year guarantee.
Do you guarantee your work?
Yes: twelve months. If anything isn’t right with the work within the year, let us know and we will sort it.
I rent my home. Can I book you?
We are happy to deal with the tenant, landlord or agent. Get your landlord’s agreement first.
Can I do it myself?
A DIY attempt doesn’t rule out a professional job. We remove it and do the joint properly.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it peels away and traps moisture behind it. Everything old must be removed first.
