Construction mastic for businesses in West Green

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Looking after the joints

After handover, a little attention goes a long way:

  • Record the products used in the O&M file
  • Brief the final clean team to avoid blades near sealant
  • Check frame gaps are within the sealant’s range before sealing
  • Use the product the specification names

After we’ve sealed an area, it helps to keep other trades from damaging the joints. New beads should be left to cure before cleaning or decorating nearby; we confirm the time for each product.

In wet areas, a weak sanitary joint shows up quickly once the building is occupied. Water gets behind trays, vanity tops and panels, leaving the remedial work to the contractor. Getting the product and preparation right first time avoids that.

Construction mastic in West Green, done properly

Buyers, tenants and clients notice sealant lines long before they notice the structure. Untidy or missed joints are among the commonest snag items, and every return visit costs time. Our aim is joints that pass at the first inspection, whatever the size of the scheme. The enquiries we see most involve new external sealant already peeling away and cracks opening in caulked internal joints, on sanitary and kitchen joints, floor and skirting junctions and brick and block movement joints. Whoever orders the work in West Green, the brief is usually the same: a clear scope, tidy work and joints that don’t fail again.

In a smaller place such as West Green, construction tends to mean small housing schemes, conversions and extensions to community buildings. Small schemes still need window perimeters, facade joints and internal sealant done to the specification.

We sign every job off with a 12-month guarantee. It’s a plain promise: if our work fails within that year, we put it right.

What the job involves on each surface

Internal decorators’ caulk

Caulking is often done in a hurry by whoever’s on site. A neat, consistent caulk line makes the decorators’ job quicker.

Kitchens and utility areas

Worktop upstands, sinks and splashbacks are sealed once the kitchen is fitted. A kitchen-suitable sealant is used and hygienic or food-safe grades wherever food contact is possible.

Questions about West Green

Is West Green too small for you to travel to?

Not at all: smaller places are covered as well as towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

Could you schedule work at a campus like Crawley College for the vacation?

Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Which sealant will you use?

The specification comes first, if there is one. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

What about RAMS and site documents?

Requirements differ from site to site, so tell us what you need and we’ll confirm it when we quote.

Will you come and look before quoting?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.

Are you CHAS accredited?

Our applicators are CSCS-carded, and we hold CHAS accreditation and Constructionline membership. Tell us what site paperwork you need and we will confirm with the quote.

Can you work while the building is occupied?

Yes, with some planning. Tell us your site hours and access windows and we’ll plan around them.

Advice

Common problems we fix in West Green

Most mastic snags on new buildings come from sequencing rather than product. Sealing before decorators, flooring or other trades have finished leaves joints exposed to damage.

Most enquiries start with one or more of the following:

  • New external sealant already peeling away
  • Mastic snags holding up handover
  • Caulk cracking where joints are moving more than expected
  • Failed sealant in an existing building being refurbished

For a contractor working at a hospital such as Crawley Hospital, 0.5 miles south-west of West Green, perimeter and facade sealing is planned around patients and deliveries.

Questions to ask before you book

  • What site paperwork they can supply
  • Their public liability cover
  • Will CSCS-carded applicators be on site?
  • How the joint faces will be prepared and primed

How to choose a sealant contractor

Owners, agents and contractors

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.

We work for building owners and managing agents on everything from one building to a spread of sites. One quote can cover more than one site, which keeps the paperwork simple.

Quoting for work in West Green

Sealant work doesn’t have a standard rate, because every site is different. What we look at:

  • Which sealant the job calls for
  • The site’s rules and procedures
  • Whether the work must be split into stages
  • Joint width, depth and condition

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.

Details that help us quote

There’s no need for a formal survey. A few details are enough to get going:

  • The type of building and who uses it
  • Access details, including height
  • The product your specification calls for
  • The asbestos register, for older buildings

Construction mastic in West Green: the local picture

Crawley, one of the planned towns of the twentieth century, takes in or adjoins West Green. Buildings from that era are frequently being refurbished, with new windows and panels set into older structures. Plenty of hotels sit less than 2 miles from West Green. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight.

For a contractor at a hotel such as The George Hotel, which lies south of West Green, the mastic often has to be finished before a reopening date. For contractors refurbishing units at places like Crompton Fields Business Park, 0.5 miles north-east of West Green, the mastic covers cladding panels, roller-door and window perimeters.

West Green is about 1 mile north of Crawley, in West Sussex. Businesses, contractors and managing agents in West Green can call on us for mastic packages. West Green is one of 373 places we cover in West Sussex. We also cover Brighton, around 20 miles from West Green.

Commercial sites across RH11 and RH10 are covered for mastic packages. For a building on Bank Lane, Swift Lane and Raven Lane or nearby, send details and we’ll quote for mastic packages. Just outside West Green, we also work in Langley Green (1 mile north), Crawley (1 mile south), Southgate (1 mile south), Three Bridges (1 mile east) and Tilgate (1 mile south-east). Nearby towns on our patch include Horsham (7 miles south-west), Haywards Heath (10 miles south-east), Burgess Hill (12 miles south), East Grinstead (8 miles east), Billingshurst (13 miles south-west) and Roffey (6 miles south-west).
