After the work
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Share your contractor requirements early
- Have the asbestos survey to hand for older buildings
- Prioritise elevations facing the weather
- Group repairs into a planned programme
Keep records of when each building was resealed. It helps plan the next round and gives you a history.
Failed mastic often goes unnoticed until heavy rain finds it. Acting at the first signs keeps it a straightforward reseal and the complaints that come with it.
Mastic sealing for commercial buildings in Broomer's Corner
For over 20 years we have resealed joints for owners, agents and landlords. Every applicator holds a CSCS card and we hold public liability insurance. Each building we complete carries a 12-month guarantee on our workmanship. The enquiries we see most involve complaints coming in block by block and patchy repairs in mismatched sealant, across window and door perimeters on blocks, shopfronts below residential blocks and balcony and threshold joints. Facilities teams, main contractors and managing agents in Broomer's Corner tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
For buildings around smaller places like Broomer's Corner, we group work so one trip covers it. Photos of each elevation help us quote accurately.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Doing it in-house
Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

From enquiry to sign-off
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. Jobs in and around smaller places like Broomer's Corner are typically planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.
- We check the asbestos register for older buildings and look at the joints.
- A fixed quote covers the joints, products and order of work.
- Failed mastic is removed completely.
- The joints are prepared and resealed with the right product.
- Buildings are completed in turn.
What we need from you
- Point out any areas we must not close
- Send asbestos survey details if the building is pre-2000
- Move anything stored against the joints

Send us photographs, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.
Related advice
What we are called out for in Broomer's Corner
Buildings move with temperature and moisture, and every joint has to stretch and squeeze with them. A joint that was too narrow, too thin or the wrong product can’t cope and fails early.
What tends to prompt an enquiry:
- Occupiers reporting cold air round windows
- Damaged joints in communal entrances and corridors
- Cracked, hardened mastic round windows on a block
- A mix of products and colours from past repairs
If your remit includes a building such as William Penn School, frame and door mastic can be programmed for the holidays.

For managing agents and facilities managers

Questions we’re asked in Broomer's Corner
Do you cover business parks and estates near Broomer's Corner, such as Crays Court (business park)?
Yes. Our area takes in Broomer's Corner and its surroundings, with estates and business parks such as Crays Court (business park) included. Photos and a short description are enough for a first look.
Can you quote for a block close to Billingshurst station?
Yes. Blocks of any size are within what we do. Photos of each elevation help us quote accurately.
How many days will you need on site?
It depends on the scope, though a typical visit typically takes one or more days per building, depending on the joint lengths and the access. For bigger or phased jobs, we will set out a timescale with the quote.
How do you choose the sealant?
Where there’s a specification, we use the product it names. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.
When is resealing likely to be due?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.
Can weather delay the job?
Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.
Can you reseal a whole block or estate?
Yes. Each building is inspected, quoted and scheduled in turn, and the programme can start with the worst.
Honest limits
Before quoting, we check that sealant is the right answer. It won’t put right:
- Broken glass or failed sealed units
- Leaks from above rather than through a joint
- Masonry that has broken away beside the joint
Not sure which it is? You can call 01277 525 020 or send details through our quote form and we will tell you honestly.
