Mastic sealing in Lancing
Older blocks and commercial buildings can have mastic that contains asbestos. Before we disturb it, we ask to see the asbestos register or survey, and work stops for testing if there’s any doubt. We don’t remove asbestos-containing materials. The enquiries we see most involve complaints coming in block by block and estate-wide sealant that is simply worn out, across shopfronts below residential blocks, balcony and threshold joints and external wall and movement joints. For commercial sealant work in Lancing, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Owners with buildings around smaller places like Lancing often group mastic work so one visit covers several properties. Send the addresses and photographs and we will quote for all of them together.
A 12-month guarantee applies to all our work in West Sussex. If an installation problem shows up, speak to us on 01277 525 020 or email drawings and photos and we’ll arrange a return visit.

FAQs: Lancing
Our building in Lancing is near the coast: does that change the sealant?
It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.
Is Lancing off your patch?
Not at all. Lancing is within our area. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
What will the job cost?
That depends on the job: quantities, access, the product and any phasing. Call for a fixed quote.
How soon can the area be used again?
We will confirm how long the chosen product needs to cure.
Can weather delay the job?
It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Indoors, the weather is rarely a problem.
What about access for upper-floor joints?
Access is discussed and agreed before the quote is fixed. Tell us the number of storeys and whether scaffold or other access is planned and we’ll confirm the approach in the quote.
Why act early in Lancing
Sealing over failed mastic looks tidy for a while. It won’t grip the old sealant and soon comes away. Full removal and proper preparation is what lasts. For buildings in places like Lancing, one well-planned visit beats several small ones, so it’s worth dealing with every failing joint at once.
We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote.

Looking after the joints
Problems stay small when the joints are checked regularly. In particular:
- Mention RAMS, insurance or CSCS requirements up front
- Keep bins and bikes away from communal door frames
- Have the asbestos survey to hand for older buildings
- Track which buildings were done and when
Where a paintable product was specified, it can be painted after curing. Silicone normally can’t be painted, so keep decorators off it unless told otherwise.
Water getting in round frames can damage plaster, decoration and the frames themselves. Resealing early keeps the job small.
Our process
We follow your site rules from the start: signing in, inductions and any permit to work. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. If neighbouring businesses or buildings around Lancing need work too, visits can be combined. Tell us your site hours and we’ll plan around them.
- 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.

Cost factors for mastic joints
Your fixed quote is built from the real scope. It takes account of:
- Backing rod, priming and other preparation
- Working within restricted access windows
- Induction, permit and paperwork requirements
- Access and working height
Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
Details that help us quote
A good diagnosis starts with the right details. Let us know:
- Any specification or named product
- How the joints are reached, and at what height
- Asbestos survey details if the building is older
- Rough lengths or quantities, or drawings if you have them
Every quote starts with the facts: the joints involved, quantities, access and the product called for. Share whatever details you have and we’ll fill any gaps with a visit.
General trades versus a specialist
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 normally costs more in the end than doing them right.
What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Block-wide mastic in Lancing
Lancing is within about 1 mile of the coast. Blocks and commercial buildings facing the sea take the most weather on their window perimeters and external joints, so it’s worth inspecting those sides more often. At about 47 miles from central London, Lancing is within reach of the capital. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres, and window and balcony mastic on them tends to age at the same rate.
Blocks of flats and mixed-use buildings often cluster around stations such as Lancing station (under half a mile south-west of Lancing) and their window and balcony mastic tends to age at the same rate across a building. If you own or manage units on a site such as Lancing Business Park, which lies south-west of Lancing, failed mastic on frames, door surrounds and external joints can be dealt with unit by unit. Historic properties like Portslade Manor, 4.6 miles to the east of Lancing, show the age of some local stock, where frame mastic must suit soft brick or stone.
