Your questions answered

Is Stirling Business Park, near Bullsmoor, within your area?

Yes. Our area takes in Bullsmoor and its surroundings, with estates and business parks such as Stirling Business Park included. Send details of the unit and the work through our quote form for a quick quote.

Do you work in London buildings with loading restrictions?

Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. The building manager’s rules go straight into our method. We allow for the ULEZ, which covers every borough

Do you take on multi-site work?

Yes. Several buildings can share a single quote, and you deal with one contact throughout.

What site paperwork can you supply?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.

Can staff carry on working while you’re here?

Yes, with some planning. We agree a sequence with your contact so just one area at a time is disrupted.

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.

Do you work to architects’ specifications?

Yes. The specification and the manufacturer’s installation guidance are what we work to.

Construction mastic in Bullsmoor

Mastic tends to be one of the final packages before handover, which puts it right on the critical path. Mastic Doctor takes on mastic packages for main contractors and developers, sealing plot by plot or floor by floor as areas are released. Site teams most often ask us about bath and shower joints scraped during the final clean and failed sealant in an existing building being refurbished, on internal decorators’ caulk, window and door perimeters and cladding and panel joints. For commercial sealant work in Bullsmoor, you deal with one contact from quote to sign-off, whether it’s one building or several.

Building sites in London tend to be tight: small compounds, delivery slots and shared hoists and scaffold. We fit around the programme, sealing each elevation or floor as other trades hand over.

Whoever the client is, the cover is the same: twelve months on the work we carried out. It doesn’t extend to damage, faults in the building or work by others, and we’re upfront about that.

What the job involves on each surface

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, and any bath is loaded with water first where that’s the agreed method.

External facade and movement joints

Brickwork, blockwork and panel movement joints need a sealant with the right movement capability. Depth is controlled with backing rod so the bead bonds to two sides only.

For managing agents and facilities managers

As a CHAS accredited contractor and Constructionline member, we’re straightforward to vet for your supplier list. We are fully insured, and our insurance certificate can go with the quote.

Building owners and managing agents use us on everything from one building to a spread of sites. One quote can cover more than one site, so there’s one set of paperwork to deal with.

What happens if it’s left?

Leaving mastic to whichever trade is fitting the element can look cheaper on paper. 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. Access in London is hard enough to arrange once, so it makes sense to deal with every failing joint while access is in place.

A quote for mastic packages depends on how many there are, their condition and the access, plus any specification you’re working to. Call for a quote.

Keeping the joints sound

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Check frame gaps are within the sealant’s range before sealing
  • Note which sealant went where at handover
  • Use the product the specification names
  • Ask cleaners to use soft cloths around fresh sealant

Record which products went where in the handover file. Future maintenance is easier when the products are known and avoids guesswork when joints are renewed. We can confirm the handover information you need when we quote.

External joints sealed in poor weather are a common cause of early failure. Holding off until conditions suit avoids callbacks so external sequencing builds in some flexibility.

Facades, frames and programmes in Bullsmoor

As part of Greater London, Bullsmoor is inside the ULEZ, which applies to every van on site. London sites also mean booked deliveries and limited storage, which the mastic programme has to allow for. There are several hotels within about 2 miles of Bullsmoor. When hotels extend or refit, the work is usually squeezed between peak periods, mastic included.

For contractors at a college like Capel Manor College (0.5 miles north-west of Bullsmoor), perimeters and internal sealant are timed for the holidays. For a contractor working at a hospital such as Cheshunt Community Hospital, 1.7 miles to the north of Bullsmoor, perimeter and facade sealing is planned around patients and deliveries. Recladding or extending a unit at a site like Stirling Business Park, 1.1 miles north-east of Bullsmoor, brings panel joints and frame perimeters into the programme.

Bullsmoor is about 2 miles north-east of Enfield, in Greater London. Our applicators travel to Bullsmoor for work on mastic packages, handled exactly as we handle every other area. Bullsmoor is one of 764 places in Greater London on our list. Our London page has more on work in that area (12 miles or so).

If you need construction mastic in EN3, EN1 and EN8, the process matches everywhere else we work: send details, get a quote, we seal, guaranteed. Among the streets we cover are Capel Road, Unity Road and Kempe Road. Access to Bullsmoor is via the M25 among other routes. If your building is just outside Bullsmoor, we cover Bulls Cross (1 mile west), Enfield Wash (1 mile south-east), Freezywater (1 mile east), Enfield Highway (1 mile south) and Enfield Lock (1 mile south-east).

Doing it in-house

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

How a job runs

Working in a building that stays open takes some planning. The work area is signed and kept contained, keep walkways clear and move on in phases so staff and visitors can carry on around us. For a job in Bullsmoor, access comes first. Send the building rules and access times with your enquiry.

  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. Problems we find, such as oversized gaps, are raised right away.
  6. The package is closed out, snags cleared and backed by 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
  • Move anything stored against the joints
