Wick Hill External Mastic
Professional external mastic in and around Wick Hill, with old sealant always removed completely and a 12-month guarantee.
- Old sealant gone brittle and cracked
- Water getting into walls through failed joints
- Joints pointed up with cement by mistake
Work for landlords, hotels and businesses
Failed sealant is one of the commonest items on a check-out report. We can quote for more than one property at once.
Water getting past a failed joint can damage the building, which is a bigger problem in a rented property. Keeping joints in good order is simple maintenance.
External mastic in Wick Hill, done properly
Low-level joints can usually be done from the ground. Where joints are higher up, tell us about the building when you get in touch and we will confirm what’s needed to reach them safely. If you have brick movement joints where the sealant has split and sealant that has lost its bond to the brick or render, we can put it right, on copings & trims, concrete & block and render & cladding joints alike.
Outbuildings, garages and conservatories around homes in places like Wick Hill add more joints to look after. Leaks generally start at a gutter end, a garage door frame or where an extension meets the house.
The work is covered for a year after we finish. If there’s a problem with it, please ring 0345 464 0079 or drop us an email.

Wick Hill buildings and the weather
Bracknell, which Wick Hill is part of, is one of England’s post-war new towns. Many homes date from the post-war decades and were built in phases, so neighbouring houses often have rooflines and wall joints of the same age, wearing out at the same time. The South East is one of the drier parts of the UK, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast.
For an older house near a landmark such as Holy Trinity Church, an extension built onto an older house moves differently, and the joint between them takes the strain. Letting a property close to Bracknell station? Then outside joints that have cracked can let damp into a rental, so check them between lets. For site and facilities teams at buildings such as Warfield Church of England Primary School, movement joints, cladding joints and gutters on larger buildings need the same care as a house’s.
Wick Hill is about 1 mile north-east of Bracknell, in Bracknell Forest. Jobs in Wick Hill get the same care as everywhere else we work: the old material taken out, joints prepared properly and a 12-month guarantee. Wick Hill is one of 41 places in Bracknell Forest we cover for external mastic. Reading is on our list too, around 10 miles away.

Being one of Bracknell Forest’s larger places, Wick Hill has every kind of property, from flats to offices.
What’s near Wick Hill

For rail, the closest station is Bracknell station, about 0.7 miles south-west of the centre. Well-known places in the area include Heatherwood Hospital (2.4 miles east) and The Lexicon (0.5 miles south-west). The countryside around Wick Hill includes Heath Lake and Holt Copse & Joel Park.
How the visit works
Once we’re on site, we check the joints match what you told us. If anything is different, we explain it before carrying on. After that, the work takes a few hours for a handful of joints, longer for a whole elevation. Parking around Wick Hill is normally easier than in a town centre, but mention any lanes, gates or long drives. For outside work, side access and the height of the joints help us plan.
- First we look over the joints with you, agree which to renew and talk through access.
- We cut out the failed sealant and rake out any dirt or growth.
- We clean both faces of the joint and prime them where the product calls for it.
- We push in closed-cell backing rod so the sealant is the right depth and bonds to the sides only.
- The new sealant, chosen to suit the brick or render, is applied and tooled to a neat finish.
Getting ready for the visit
- For indoor joints, keep the area dry beforehand if you can
- Mention any sign-in or site rules at work premises
- Plan for the work area to be out of bounds to pets and children
Ask for a quote
The more we know about the job, the more useful the quote. Let us know the location, the problem and roughly how many joints, and email pictures if that’s easy.
Related advice
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 the sealant in it must stay soft and stretchy.
Concrete and blockwork
Concrete and block walls shrink as they dry and move with temperature. Their movement joints are sealed over backing rod with a flexible sealant.
What affects the cost of external mastic
The price is agreed before any work begins. It’s based on:
- The type of sealant required
- Working hours on commercial sites
- How many areas need sealing
- The amount of work
A few things move the cost up or down: how much old sealant there is and how stubborn it is, whether mould needs treating, and whether we need extra access for height. Your quote takes all of that into account.
What we need to know
Photos by email are helpful but not essential. Try to tell us:
- A few pictures by email, if you can
- Access, such as stairs, a lift or height
- The type of property
- What’s wrong with the joints now
Quotes start with a quick conversation. Describe the problem, the location and the size of the job, and we’ll explain how we’d tackle it. Whenever you’re ready, phone 0345 464 0079 or send us an email.
DIY sealant or a professional job?
Sealing over old silicone is the commonest DIY error. Silicone does not stick to old silicone, so it lifts and traps water and mould underneath. Everything old must be removed first.
Some jobs are best left to a professional: work at height, external movement joints, fire-rated sealant and large areas call for the right materials, safe access and experience.
Honest limits
We won’t take on work that won’t last, so here’s what sealant can’t put right:
- Structural movement, which needs a surveyor or engineer
- Walls that need new movement joints cut into them
- Rising or penetrating damp from elsewhere in the wall
If you are not sure, just ring 0345 464 0079 or drop us an email and we will give you a straight answer before booking.
Surfaces we seal
- Joints between brick and frames
- Render & cladding joints
- Façade panels
- Copings & trims
- Brickwork movement joints
- Concrete & block
Why deal with it now?
The longer a joint stays open, the more water the wall takes in. Wet masonry is more easily damaged by frost around the joint, so the problem grows beyond the joint itself. Homes in smaller places like Wick Hill can face more weather, and failed outside joints let damp into walls. Inside, a split seal lets water into floors and panels just as it would anywhere.
Commercial jobs are quoted on the same basis as homes: the amount of work, the access and the products needed, plus any working-time requirements on site. Ask us for a quote and we’ll explain what it covers.

Common questions in Wick Hill
Do older homes in Wick Hill need their sealant replacing?
Generally, yes, if it’s cracked, shrunk, mouldy or coming away. New sealant won’t stick to old, so the old bead has to come out completely first.
I let a flat near Bracknell station. Can you help?
Yes, we work for landlords and agents. You can call 0345 464 0079 or drop us an email with the address and a few details, and we’ll give you a fixed price before we start.
What does external mastic cost?
The cost depends on the size of the job, access and how much old sealant has to come out. Ask us for a quote.
What colours does the sealant come in?
Exterior sealants are made in a range of colours, from greys and browns to whites and stone shades. We pick the one that suits your wall best so it doesn’t stand out.
How long will you be here?
Most jobs take a few hours for a handful of joints, longer for a whole elevation, including preparation and clearing up. Your quote will say how long we expect yours to take.
Is it OK to fill a movement joint with cement?
No, not where the gap is a movement joint. Pointing it stops it working. A flexible sealant is the right fill.
What’s an expansion joint in brickwork?
It’s a deliberate gap that lets the wall expand and contract without cracking. It’s sealed with a flexible sealant, not mortar.
Will the old sealant be removed?
Yes. We cut out all the old sealant and clean the joint.
