External Mastic in Brighton Hill
Our applicators work in Brighton Hill on sealing brickwork movement joints, render, cladding and façade joints. Old sealant removed completely, joints prepared properly and every job guaranteed for a year.
- Plants rooting in failed movement joints
- Movement joints filled with mortar instead of sealant
- Joints with sealant missing in places
DIY sealant or a professional job?
What a professional job adds is preparation and the right product. Joints are cleaned back to sound surfaces and dried, and the sealant is chosen for how the joint moves and where it is, then guaranteed for a year.
Overfilling a joint is a classic DIY mistake. A heavy bead looks messy and copes badly with movement, and getting the depth right matters as much as the look.
About our external mastic in Brighton Hill
Low-level joints can generally 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. We work on brickwork movement joints, joints between brick and frames and façade panels, and people most often call us about weathered mastic that no longer stretches and movement joints with cracked, split or missing sealant.
Outbuildings, garages and conservatories around homes in places like Brighton Hill add more joints to look after. Gutter ends, garage door frames and the joints where an extension meets the house are typical spots for leaks.
Whatever the size of the job, it’s backed by our one-year guarantee.

What we’re called out for in Brighton Hill
Poor preparation causes many early failures: joint faces that were dusty or damp, unprimed where they needed it, or still carrying old sealant. The new sealant then lets go long before it should.
Most people get in touch after spotting one of these:
- Weeds or debris growing in open joints
- Water getting into walls through failed joints
- Cracked joints where brick meets render or frames
- Movement joints with cracked, split or missing sealant
Letting a property close to Basingstoke station? Then failed wall and movement joints let damp in, so they’re worth checking between tenancies.

Brighton Hill questions
Can you help a landlord with a rental near Basingstoke station?
Yes, we work for letting agents and landlords. You can ring 0345 464 0079 or send us an email with the address and a few details, and we will give you a fixed price before work begins.
Is Brighton Hill within the area you cover?
Yes, Brighton Hill is covered. Our work covers London and the South East, from towns to the smallest places. Longer journeys are simply planned in advance.
Do you remove the old sealant?
Yes. We cut out all the old sealant and clean the joint before resealing.
Where is Mr Mastic based?
Mr Mastic is based in Crawley. Our applicators cover Brighton Hill.
Does someone need to be in?
It depends on the job. For work indoors, someone needs to let us in, while outside work can sometimes be arranged differently.
Should I point up the gap in my brickwork?
No. Mortar locks the joint solid, so the movement cracks the wall elsewhere. It needs a flexible sealant over backing rod.
How do I get a quote for external mastic in Brighton Hill?
It depends on the job, so we quote each one individually. To get one, call 0345 464 0079 or send us an email with a short description of the job.
Is the work guaranteed?
Yes: twelve months. If there’s a problem with our work in that time, tell us and we’ll put it right.
What affects the quote in Brighton Hill
We do not publish a price list, because no two jobs are the same. The quote depends on:
- Working hours on commercial sites
- How many rooms, windows or areas are involved
- The old material and how stubborn it is
- The type of sealant required
What it costs depends on how much there is to do, how hard the old material is to remove and how easy the joints are to reach. You will have a clear quote before any work starts.
What to tell us for a quote
What to tell us when you ask for a quote:
- A few photos by email, if you can
- The type of property
- The address or postcode of the job
- What the problem is, such as mould, gaps, leaks or cracking
Every job is quoted individually. Just ring 0345 464 0079 or send us an email with the details.
For landlords and businesses
In hotels, rooms out of use cost money, so we plan the work room by room. Hotel work is part of what we do, alongside homes and businesses.
We also work for businesses, from offices to washrooms and kitchens. For commercial premises, we can talk through working times when we quote.
Why deal with it now?
Water gets in through a failed movement joint and can run behind render or cladding. Resealing early keeps the job to the joint itself, rather than the wall around it. Homes in smaller places like Brighton Hill can face more weather, and failed outside joints let damp into walls. Indoors, a failed seal lets water into floors and panels as it would anywhere.
Every job is a little different, so each one gets its own quote. Size, access and the product the joint needs all make a difference, and we will explain the quote if you ask.

External mastic in Brighton Hill: local notes
Compared with the north and west, the South East gets less rain, but outside sealant still needs a dry, clean surface, so outdoor work is planned around the forecast. With historic houses such as The Vyne (about 4 miles north) nearby, there’s older building stock in the area around Brighton Hill as well as newer homes. 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 The Church Of Christ The King, old and new materials meet at the roofline and walls, which is where sealant earns its keep. Managing a site like Brighton Hill Community School? Then larger buildings have long runs of movement joint that eventually need resealing.

How the job changes by surface
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. That movement goes into the joint, so the sealant in it must stay soft and stretchy.
Joints between dissimilar materials
Joints where frames, sills or panels meet the wall are common leak points. We cut out the old sealant and reseal with a product suited to both surfaces.
What happens on the day
On the day, we look over the joints with you first. We protect the surfaces around the joints before any work begins. The work generally takes a few hours for a handful of joints, longer for a whole elevation. A visit to Brighton Hill is planned like any other: the time, the access and where to park are agreed in advance. If the work is outside, the weather plays a part, as sealant needs a dry surface.
- First, the joints are inspected and the access agreed.
- We cut out the old mastic and rake out anything in the joint.
- The faces are brushed clean and primed where the product requires it.
- Backing rod sized to the joint goes in to set the depth.
- We apply the sealant, tool it and check the whole run.
How to prepare
- For business premises, tell us about site rules or sign-in
- Try not to wet indoor joints just before the visit
- Let us know about earlier repairs to the joints
