Need mastic sealing in Hollingbury?
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
When to call us in Hollingbury
The edges of the material itself sometimes break away for example where render or brick edges crumble. If the edges are unsound, we say so before quoting the sealing.
What tends to prompt an enquiry:
- Window mastic that has split and shrunk
- Movement joints with sealant missing
- Leaks at window and door perimeters
- No planned programme for sealant
For owners of several units at places like Hollingbury Industrial Estate, which lies north-east of Hollingbury, one programme can deal with frame and external mastic across the lot.
What your quote should include
- Whether their applicators hold CSCS cards
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Will failed sealant be removed rather than covered?
- How they handle RAMS and site documents
Mastic sealing in Hollingbury, done properly
There isn’t one mastic for every joint on a building. Low-modulus neutral-cure silicone suits many window perimeters and external movement joints, while hybrid polymer sealants grip many materials and are often paintable. We will confirm the colours available for the specified product. We work on external wall and movement joints, balcony and threshold joints and shopfronts below residential blocks, and what we’re called in for most is leaks at window and door perimeters and draught complaints from residents or tenants. Most enquiries from Hollingbury start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Converted and older buildings in and around Hollingbury often put modern windows into old walls. Perimeter joints need a sealant that suits both frame and masonry.
The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Mastic sealing around Hollingbury: how the place shapes the job
Hollingbury lies within about 3 miles of the sea. For owners and agents with buildings near the sea, exposed elevations are where frame mastic fails first; plan inspections around that. The 2 miles around Hollingbury include eight care or nursing homes. Frame mastic on care buildings is best renewed elevation by elevation, with the manager deciding timings.
Historic properties like Preston Manor & Gardens, 1.4 miles to the south-west of Hollingbury, show the age of some local stock, where frame mastic must suit soft brick or stone. Blocks of flats and mixed-use buildings often cluster around stations such as Moulsecoomb station, 1.1 miles to the south-east of Hollingbury, and their window and balcony mastic tends to age at the same rate across a building.

What sealant work can’t fix

- Broken glass or failed sealed units
- Materials that need asbestos testing before work
- Masonry that has broken away beside the joint

Questions about Hollingbury
Does a coastal location like Hollingbury affect which sealant is used?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We check the specified product suits the exposure and pay close attention to preparation.
Can you work at a site such as Hollingbury Industrial Estate, by Hollingbury?
Yes. Our area takes in Hollingbury and its surroundings, with estates and business parks such as Hollingbury Industrial Estate included. A few photos and the unit address let us price the work.
What guarantee do you give on resealing?
Our workmanship carries a 12-month guarantee and we hold public liability insurance.
Can people stay in the building while you reseal?
The work is planned around occupiers. Dates and areas are agreed with you so residents or tenants can be told, and entrances stay in use.
When can the area be used after sealing?
The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, and we confirm it before leaving site.
Do you seal on top of existing sealant?
No. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
Can you take on resealing for a block portfolio?
We do. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work and work can be quoted per building or as a whole.
Building owners, agents and FMs in Hollingbury
We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Hollingbury can sit alongside others in a wider programme across Brighton and Hove.
Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.
Why deal with it now?
Failed perimeter mastic lets cold air in around frames and the windows usually get the blame. In many cases, new perimeter sealant deals with it where the frames themselves are sound. Over time, UV, weather and movement wear any sealant out. Renewing it in good time keeps the building weathertight.
Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well, along with the time of year for external work.
What you get with us
- Constructionline member for supplier checks
- Joints cleaned back to sound surfaces
- RAL and finish matching where the product range allows
- 12 months’ guarantee on every job
How the quote is worked out
To price the job, we consider:
- The total length or number of joints
- Site requirements such as inductions and permits
- Whether old sealant has to be cut out first
- How accessible the joints are
We don’t publish prices, since every building and every scope is different. Call for a quote.
Sending details for a quote
The more we know, the firmer the quote. When you get in touch, include:
- Photos of the joints, close up and from further back
- When you need the work done
