What affects the quote in Brock Hill
You will get a clear quote before any work starts. It’s based on:
- How much old sealant there is and how hard it is to remove
- Which sealant suits the joint
- Working hours on commercial sites
- Whether there’s mould to deal with
Leaving a failed joint usually makes the job bigger, not smaller, because water and mould keep working on it. If you’re unsure, ring 0345 464 0079 or send us an email for an honest opinion and a quote.

About our external mastic in Brock Hill
We are ARBOMaster approved applicators, and each external joint gets a sealant suited to it. Some surfaces need a primer before sealing, and we do not skip that step. We are often asked to deal with cracked joints where brick meets render or frames and weeds or debris growing in open joints, across concrete & block, façade panels and render & cladding joints.
External sealant needs dry, clean surfaces, so work around Brock Hill is planned for dry weather. Let us know about access to every wall, plus any garages or outbuildings.
The work is guaranteed for twelve months. If there’s a problem with our work within the year, let us know and we will sort it.

Why act early in Brock Hill
Pointing a movement joint with mortar might seem a neat fix, but it stops the joint moving. The movement then cracks the brickwork or render nearby. A flexible sealant over backing rod is what the joint needs. In a small place like Brock Hill, homes can be exposed to wind and rain, which finds any gap, and damp in older walls is slow to dry out.
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’ll explain the quote if you ask.
Why us?
- Sanitary silicone with an anti-fungal additive in wet areas
- Approved under the ARBOMaster scheme
- We are fully insured
- Domestic, commercial and hotel work

Questions from Brock Hill
Do you cover Brock Hill for external mastic?
Yes. Our work covers London and the South East, and Brock Hill is part of that. Just call 0345 464 0079 or drop us an email with a few details of the job.
Is Brock Hill within the area you cover?
Yes. Brock Hill is within the area we cover, which takes in towns, villages and rural addresses. Our work covers London and the South East. Let us know about access, parking and anything unusual about getting there when you book.
Is there any odour?
That depends on the sealant. Some smell for a while, some hardly at all, and any smell fades as they cure.
How long does the job take?
That depends on the amount of work, but most jobs take a few hours for a handful of joints, longer for a whole elevation. We’ll tell you when we quote.
Can you reach joints on upper floors?
That depends on the building and the joints. We work on joints that can be reached safely. Tell us about the building and we’ll confirm what access is needed.
What do you need from me for a quote?
A short description and the location. We will ask anything else we need to know.
Will the new joint stand out?
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.
Do you work for hotels and businesses?
Yes. Commercial and hotel work is a large part of what we do. We can talk about working times when we quote.
How the job changes by surface
Brickwork movement joints
Clay brickwork grows slightly over its life and moves with the weather. The movement joint takes that up, so its sealant has to stay flexible.
Copings and trims
A failed coping joint lets water into the top of the wall. Resealing them is a small job that protects a lot.
For landlords and businesses
If you manage several properties in or around Brock Hill, several properties can be quoted together. Just tell us the addresses and what each one needs, and photos by email help.
Mouldy or split sealant often shows up at the end of a tenancy. We can quote for more than one property at once.
Brock Hill buildings and the weather
London and the South East are among the drier parts of the UK, though outdoor sealant still has to go onto a dry joint, so the forecast decides the day.
If you look after a building such as Beauchamps High School, its movement joints, gutters and trims need looking after like any other building’s. Homes close to Church of St Margaret include some older properties, and an extension built onto an older house moves differently, and the joint between them takes the strain.

Looking after it afterwards
To keep the joints looking good and working properly:
- Show decorators and builders where the movement joints are
- Keep water from gutters off the wall
- Ask before painting over external sealant
- Have failed joints looked at early
Don’t let soil, plants or ivy build up against the new joints. Anything that holds water against the joint wears it out sooner.
Small splits are the time to act. Then it’s a straightforward cut-out and reseal.
When to call us in Brock Hill
Every building moves. Clay bricks expand slightly over their life, concrete and block shrink, and everything moves with temperature and wet. The sealant in the movement joints takes that strain.
These are the problems we’re asked about most:
- Weathered mastic that no longer stretches
- Moss and dirt in joints with no sealant left
- Rigid filler in a joint that should flex
- Brick movement joints where the sealant has split
Letting a property close to Wickford station? Then split movement joints are easy to miss on a rental until damp shows inside.
Questions to ask before you book
- What happens if they find a problem under the old sealant
- When the joint can take water or movement
- The length of the guarantee
- Is the old sealant removed completely?
The process
Good joint work is mostly preparation, and we do not rush it. Every joint is cleaned and dried before new material goes in. In total, it generally takes anything from a few hours to several days, depending on the building. For a village or hamlet like Brock Hill, the journey is planned in advance: let us know about lanes, gates and parking. We bring what the job needs, so it can be finished in one trip where possible.
- 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.
Before we arrive
- On commercial sites, let us know about site rules
- Let us know about parking restrictions
- Move anything stored near the joints
