When something else is needed

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. It won’t fix:

  • Deciding which fire-stopping product a penetration needs
  • Specifying the product where the designer hasn’t
  • Oversized gaps that need packing or adjustment by others

If in doubt, give us a call on 01277 525 020 or send photos by email and we will say what we think.

Surfaces we seal

  • Window and door perimeters
  • Floor and skirting junctions
  • Brick and block movement joints
  • Internal decorators’ caulk
  • Cladding and panel joints
  • Sanitary and kitchen joints

Owners, agents and contractors

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. Our insurance certificate can be sent along with the quote.

We work for building owners and managing agents on sealant work across single buildings or whole portfolios. One quote can cover more than one site, which keeps the paperwork simple.

Our process

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we are cleared to begin, we take the joints in the sequence agreed with you. If others near Butlocks Heath need work, visits can be combined. A fixed quote is given before anything starts.

  1. First we take quantities off the drawings and read through the specification.
  2. We return a fixed quote that ties the mastic package to your programme.
  3. Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
  4. Work follows the programme, area by area, as rooms and elevations become ready.
  5. Each joint is prepared, backed to depth and sealed in the product the specification names.
  6. Before handover, snags are dealt with and the package is signed off under our 12-month guarantee.

Getting the site ready

  • Tell us what induction or permit system the site runs
  • Let building users know which areas are affected
  • Send asbestos survey details if the building is pre-2000

Quoting for work in Butlocks Heath

A fixed quote reflects the actual work. It allows for:

  • The product specified
  • Joint width, depth and condition
  • Distance, for remote addresses
  • Quantities, in metres or numbers

Whether it’s a single area or a whole estate, the same things set the price: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

Sending details for a quote

It doesn’t need to be a full survey. A few details are enough to get going:

  • Approximate linear metres or a joint schedule
  • Any specification or named product
  • Photos of the joints, close up and from further back
  • How the joints are reached, and at what height

Questions about Butlocks Heath

Is Butlocks Heath off your patch?

Not at all: smaller places are covered as well as towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Can you take on a job at a hospital such as Fareham Community Hospital?

Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

What site paperwork can you supply?

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

Who decides which product is used?

The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

Do you seal on top of existing sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

How soon can the area be used again?

Curing time varies by product, and we confirm it on the day.

What happens if the weather stops external sealing?

Conditions have to suit the product before external work starts. Sealing in poor conditions risks adhesion failure, so we wait rather than redo work.

Construction mastic around Butlocks Heath: how the place shapes the job

The sea is no more than about 1 mile from Butlocks Heath. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, so joint design, primers and product choice deserve extra care.

Different surfaces, different methods

External facade and movement joints

Brickwork, blockwork and panel movement joints need a sealant with the right movement capability. We set the depth with backing rod to avoid three-sided adhesion.

Bathrooms, en suites and washrooms

In bathrooms and washrooms, an anti-mould sanitary silicone goes around every fitting. Joints are cleaned, sealed and tooled neatly and baths are loaded where appropriate before sealing.

Signs you need construction mastic in Butlocks Heath

Swapping the specified sealant for a cheaper general-purpose product is a common cause of failure. A sealant that isn’t right for the substrate or the movement will fail ahead of time. We stick to the specified product, or put any alternative to you first.

Typical triggers for a call:

  • Snag items on joints that need redoing before handover
  • Frame perimeters left unsealed or poorly sealed
  • External joints sealed in damp or cold conditions that are now failing
  • Cracks opening in caulked internal joints

For a contractor working at a hospital such as Fareham Community Hospital (2.9 miles east of Butlocks Heath), perimeter and facade sealing is planned around patients and deliveries.
