What the job involves on each surface

Fire-rated sealant where specified

Fire-rated sealant is one type of fire-stopping product. Other products are used for some services and gaps. Tell us what records you need and we will confirm with the quote.

Bathrooms, en suites and washrooms

In bathrooms and washrooms, an anti-mould sanitary silicone goes around every fitting. Each joint is prepared, sealed and finished with a neat tooled line.

What sealant work can’t fix

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Joints damaged after sign-off by following trades
  • Joint design decisions that belong to the architect or engineer
  • Faulty frames rather than failed sealant

Not sure which it is? You can phone 01277 525 020 or send photos by email and we will tell you honestly before you book.

Surfaces we seal

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

Construction mastic around Chackmore: what changes locally

Chackmore sits in one of the drier corners of the country, the South East. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so external mastic is timed for workable conditions and agreed with the site manager. Several hotels sit less than 2 miles from Chackmore. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.

On a campus such as University of Buckingham, 1.8 miles to the south-east of Chackmore, new teaching buildings and residences are typically built and refurbished around the academic year. Projects at schools like St James and St John CofE Primary School work to term dates, so mastic is programmed tightly. New units and refits on sites such as Moreton Road Industrial Estate (to the south-east of Chackmore) need their panel and perimeter joints sealed to the specification.

Chackmore is about 2 miles north-west of Buckingham, in Buckinghamshire. Commercial clients in Chackmore can call on us for mastic packages. Our Buckinghamshire coverage takes in 308 places, from busy centres to rural villages. Sites around Oxford have their own page, roughly 21 miles from Chackmore.

Your questions answered

Can you work around term dates at a campus such as University of Buckingham?

Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Do you take on work at healthcare sites like Buckingham 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.

Are you CHAS accredited?

Our applicators hold CSCS cards, and we’re CHAS accredited and a Constructionline member. Public liability insurance of five million pounds is in place too.

What guarantee comes with a mastic package?

The work is guaranteed for 12 months, covering how we sealed. Protecting sealed areas from following trades helps avoid damage.

Which sealant will you use?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

What if there’s asbestos in the old mastic?

The duty to manage asbestos sits with the building’s dutyholder, so we’ll ask for the register before work on an older building. Work pauses if suspect material is found, until it has been tested.

How much does the work cost?

Every job gets its own fixed quote. To get one, phone 01277 525 020 or use the quote form.

Why it’s worth doing now in Chackmore

Some packages split mastic across the window fitter, kitchen fitter and plumber. The result tends to be uneven finishes and arguments about who should seal what. A single mastic package gives one point of responsibility, with the same standard on every plot. For buildings around smaller places like Chackmore, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote.

Our process

We follow your site rules from the start: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact. Rural sites near Chackmore may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.

  1. We walk the site or review drawings to understand the package.
  2. You receive a fixed quote covering scope, products and sequence.
  3. Site paperwork is confirmed and our CSCS-carded applicators are inducted.
  4. Sealing follows the programme as areas are released.
  5. Any frame gaps or issues outside our scope are flagged to the site team.
  6. Final snagging is completed and the 12-month guarantee applies.

Getting the site ready

  • Have the specification and drawings to hand
  • Move anything stored against the joints
  • Tell staff and tenants when we will be in

General trades versus a specialist

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

What affects the price in Chackmore

The price varies from site to site. Expect it to depend on:

  • Phasing around occupants
  • The site’s rules and procedures
  • Joint width, depth and condition
  • Location, for remote and island sites

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote.

Sending details for a quote

The more we know, the firmer the quote. Helpful details to send:

  • The type of building and who uses it
  • Drawings or a marked-up plan, if available
  • Asbestos survey details if the building is older
  • The product your specification calls for

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, call 01277 525 020 or send details through our quote form.
