Sealing brickwork movement joints, render, cladding and façade joints for Hillway, backed by a one-year guarantee. Call for a quick quote.
- Sealant that has lost its bond to the brick or render
- Hard, crazed mastic that has stopped moving
- Water getting into walls through failed joints
Different surfaces, different methods
Copings and trims
Metal and stone copings both move with temperature, so the joints need a sealant that stays flexible in all weathers.
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.
External mastic for homes and businesses in Hillway
Movement joints let brickwork, render and cladding expand and shrink without cracking. The sealant in it has to stretch and squeeze for years, and when it fails, the wall takes the strain and water finds a way in. If you have sealant pulling away from one side of the joint and rain getting behind render or cladding at a joint, we can help.
Outside joints can only be sealed when they’re dry, so work in Hillway is booked around the forecast. Tell us about access to all sides of the building, including outbuildings and garages.
We guarantee the work for a year. If something isn’t right with it in that time, tell us and we will put it right.

Should I try it myself first?
Some jobs are best left to a professional: high-level joints, fire-rated gaps, external movement joints and big jobs need the right product, the right access and the right method.
Sealing over old silicone is the commonest DIY error. New silicone won’t bond to old, so it lifts and traps water and mould underneath. Everything old must be removed first.
For landlords and businesses
Hotels need rooms back in use, so the work can be planned room by room around your bookings where we can. Hotel work is part of what we do, alongside homes and businesses.
Businesses can book us for washrooms, kitchens, offices and more. On commercial sites, working times can be discussed when we quote.
Hillway questions
Do you cover smaller places like Hillway?
Yes. Hillway is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Just mention lanes, gates or anything else about the route when you book.
Does the coastal weather in Hillway affect outside sealant?
Coastal homes put outside sealant through more weather than inland ones, so preparation and the right sealant matter all the more. Walls facing the sea are normally the first to need attention.
How do I get a quote for external mastic in Hillway?
Every job is different, so each one gets its own quote. To get one, ring 0345 464 0079 or send us an email with a short description of the job.
What is backing rod for?
The foam is closed-cell backing rod. It stops the sealant going in too deep and bonding to three sides, which would stop it stretching.
Can you quote for more than one area?
Yes. Just list everything you need and you will get one quote.
Where are you based?
Our base is Crawley. Our area covers South East England, London and Scotland.
Can you seal joints between render and window frames?
Yes. Joints between dissimilar materials are a big part of external work. The sealant is chosen to bond to both sides, primed where needed.
When is the sealant fully cured?
It depends on the product and the conditions. Before we leave, we’ll tell you the cure time.

What we can’t put right
A few problems are outside what sealant work can do:
- Damp from another source, such as a leaking gutter or a bridged damp-proof course
- Loose or hollow render, which needs re-rendering
- Movement that is more than a sealant joint can take
If you are not sure, just call 0345 464 0079 or email us and we will give you a straight answer.

What affects the quote in Hillway
There’s no set price list, because jobs vary so much. What we look at:
- How much old sealant there is and how hard it is to remove
- Which sealant suits the joint
- Access and height
- Working hours on commercial sites
Instead of a standard rate, we look at what your job involves: how many joints, what’s in them now and how we reach them. The price is agreed before we begin.
What to tell us for a quote
There’s no need for technical detail. It helps if you can tell us:
- Where the job is, and your postcode
- Photos by email, if that’s easy
- If it’s domestic, commercial or a hotel
- What the problem is, such as mould, gaps, leaks or cracking
To get a quote, ring 0345 464 0079 or drop us an email and tell us where the job is and what the problem looks like. We will give you a clear price before any work starts.
How the visit works
At the end, we look at the finished work together. The work normally takes a few hours for a handful of joints, longer for a whole elevation, depending on how much there is to do. Somewhere like Hillway needs a little journey planning: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- First we look over the joints with you, agree which to renew and talk through access.
- Old sealant and any debris are cut and raked out.
- Both sides are cleaned back to sound material and primed if needed.
- 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.
Preparing for the visit
- Let us know about stairs, lifts or work at height
- Tell us if parking is tricky
- Tell us about any water getting in

Related advice
Do you need external mastic in Hillway?
If plants are growing out of a joint, the sealant has normally failed or was never there. Dirt and roots then trap moisture in the joint and make things worse.
These are the problems we’re asked about most:
- Brick movement joints where the sealant has split
- Rain getting behind render or cladding at a joint
- Joints pointed up with cement by mistake
- Moss and dirt in joints with no sealant left
Rented homes near Brading station change hands often, and failed wall and movement joints let damp in, so they’re worth checking between tenancies.
Questions to ask before booking
- When the joint can take water or movement
- What product goes in the joint
- The length of the guarantee
- Whether they’re fully insured
Walls and rooflines in Hillway
Hillway is within about 1 mile 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 Yaverland Manor (about 1.6 miles west) are a reminder that the area around Hillway has older buildings as well as new. In older buildings, older brick and stone need a sealant that suits them, at the right joint depth.
For an older house near a landmark such as Bembridge Methodist Church, the joints between older walls, newer extensions and the roofline need a sealant that can move. For site and facilities teams at buildings such as Bembridge Church of England Primary School, its movement joints, gutters and trims need looking after like any other building’s.
