How we handle mastic sealing in Brockbridge
Owners and agents usually inherit a building’s mastic rather than choose it, and it ages quietly: window perimeters, door frames, external joints and communal junctions all rely on it. Once it cracks, hardens or comes away, draughts and water find a way in, and occupiers start reporting it. The enquiries we see most involve patchy repairs in mismatched sealant and the same joint failures repeated across a portfolio, on balcony and threshold joints, window and door perimeters on blocks and communal entrances and stairwells. One point of contact handles commercial sealant work in Brockbridge from the first photographs to the final walk-round, whether it’s one building or several.
Owners and agents with buildings around smaller places such as Brockbridge tend to manage small terraces of association properties, converted barns and commercial units. Mastic around frames and on external joints wears out in time, whatever the building.
We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Owners, agents and contractors
We work for building owners and managing agents on sealant work across single buildings or whole portfolios. One quote can cover more than one site, so there’s one set of paperwork to deal with.
FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.
When to call us in Brockbridge
UV and rain age external sealant. The surface chalks, the body stiffens and cracks appear, especially on south and west faces.
If one of these sounds familiar, it’s time for a closer look:
- Cracked, hardened mastic round windows on a block
- Repeated reactive repairs to the same buildings
- Mastic failing across several blocks on an estate
- Communal area joints that look neglected
Older community buildings, Church of St Mary and All Saints among them, often have frames of mixed ages whose mastic varies.
Questions to ask before you book
- Their plan for phasing and protecting the area
- Will CSCS-carded applicators be on site?
- Which product they’ll use, and why it suits the joint
- Their pre-qualification and accreditations
Quoting for work in Brockbridge
These are the things that shape the price:
- How much there is to seal
- Phasing around occupants
- The size and state of each joint
- Travel to remote or island sites
Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.
What we need to price the job
A few photos plus some basic facts will normally do. It helps to include:
- The site address and postcode
- Any dates the work must fit around
- Photos of the joints, close up and from further back
- Access details, including height
We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, call 01277 525 020 or email the details over.
Leave it or put it right?
Failed perimeter mastic lets cold air in around frames, and they often blame the windows. Resealing the perimeters is often the simpler fix where the frames themselves are sound. Converted and older buildings near places like Brockbridge tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.
The specified product makes a difference, and so does the preparation. Access, phasing and site rules also count.

Questions about Brockbridge
Is Brockbridge too far out for you?
No. Small places get the same service as large ones. We work across Greater London and the South East. Good photos up front let us bring everything on the first visit.
What site paperwork comes with a job in Brockbridge?
Whatever your site asks for, from RAMS to CSCS details, is confirmed when we quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.
Are you CHAS accredited?
Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.
How do I request a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. Step one needs little more than photographs and a postcode.
Will you quote for a small job?
Small jobs are welcome alongside larger packages. Photos and a description are enough to start.
What if the old mastic contains asbestos?
Some mastics in pre-2000 buildings contain asbestos. We check the asbestos register or survey before disturbing it and suspect material is tested first.
How do you choose the sealant?
A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.
After the work
To get the most from the new sealant:
- Ask residents or tenants to report leaks and draughts early
- Have the asbestos survey to hand for older buildings
- Prioritise elevations facing the weather
- Mention RAMS, insurance or CSCS requirements up front
Keep bins, bikes and deliveries away from low-level joints where you can. Damage at low level is the most common reason communal joints fail early.
Leaks at window perimeters spoil finishes and can affect frames. Resealing early keeps the job small.
