Can you quote for a block close to Pulborough station?
Yes, we work for agents, landlords and housing associations with blocks of every size. Send the address, photos of the elevations and your access arrangements, and we’ll give a fixed quote.
Which sealant will you use?
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.
Is Coates in your area?
Yes. Sites across Coates are covered, with one number for every area we cover.
Do you supply RAMS and insurance details?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are CHAS accredited and a Constructionline member.
How long does a job like this take?
It depends on the scope, but the work typically takes one or more days per building, depending on the joint lengths and the access. Larger or phased jobs take longer, and we will give you a timescale with the quote.
How long do sealant joints last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
How we handle mastic sealing in Coates
Before work starts, most agents and landlords want the documents in order. For documents, tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We’re a Constructionline member and CHAS accredited, and we carry public liability insurance. The enquiries we see most involve draught complaints from residents or tenants and damaged joints in communal entrances and corridors, across shopfronts below residential blocks, external wall and movement joints and communal kitchens and washrooms. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Coates is the same: the right product in a properly prepared joint.
In and around smaller places like Coates, landlords and agents often look after small groups of housing association properties, converted farm buildings and community buildings. Frame and wall-joint mastic on all of them ages and hardens.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application, and if something we did falls short, we return to it.

General trades versus a specialist
For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
Mastic sealing in Coates: the local picture
Coates sits in one of the drier corners of the country, the South East. Even so, frame mastic only goes on in dry, workable conditions, and south- and west-facing elevations, which take the most sun and rain, often age first. At about 43 miles from central London, Coates is within reach of the capital. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres.
Older community buildings, Church of St Agatha among them, often have frames of mixed ages whose mastic varies. Older buildings near Coates, from historic houses such as Bignor Roman Villa, 2.1 miles south of Coates, to more modest stock, need compatible products when frames are resealed.
Coates is about 10 miles north of Littlehampton, in West Sussex. Coates sits inside our coverage, with the same fixed quotes and 12-month guarantee as everywhere else. We work across 373 places in West Sussex. Sites around Brighton have their own page, about 21 miles away.

What’s near Coates
Around Coates, our work takes us to commercial buildings near The Swan Hotel. Coates’s nearest station is Pulborough station, about 2.7 miles east of the centre.

Do you need mastic sealing in Coates?
Topping up old mastic is a common shortcut. New silicone has nothing to grip on old silicone, so these repairs rarely last.
Common reasons buildings call us in:
- Damp patches beside frames
- Estate-wide sealant that is simply worn out
- Brittle perimeter mastic across a building
- A mix of products and colours from past repairs
If your remit includes a building such as Fittleworth CofE Village School, frame and door mastic can be programmed for the holidays.
Comparing quotes
- Health and safety accreditation such as CHAS
- Is depth set with backing rod, or bond-breaker tape in shallow joints?
- Will RAMS and insurance details be available?
- Will failed sealant be removed rather than covered?

Looking after the joints
Cleaning and maintenance staff play a part too. Share these points with them:
- Avoid piecemeal callouts where you can
- Look at the sunniest and most exposed elevations first
- List the paperwork your organisation requires when you send details
- Make mastic part of routine maintenance checks
Add mastic joints to your cyclical inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away, and note the building and elevation.
Failed mastic often goes unnoticed until heavy rain finds it. Resealing when cracking first shows avoids water damage and saves internal repairs.
