Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Our process

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work usually takes a few days on a modest refurbishment and longer on multi-plot or multi-storey schemes, and we clear our waste as we work. For a building around Bockmer End, tell us how to find it and who will meet us. Add it to your enquiry and we’ll 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. Problems we find, such as oversized gaps, are raised straight away.
  6. Final snagging is completed and the 12-month guarantee applies.

What we need from you

  • Warn occupants and staff about the work
  • Make sure the joints can be reached
  • Let us know about inductions and permits

About our construction mastic in Bockmer End

Refurbishment work needs a slightly different approach from new build. Existing joints have to be stripped back to sound faces, because fresh sealant can’t key into cured silicone. After that, the joints are prepared and sealed to the specification. If you are dealing with failed sealant in an existing building being refurbished and bath and shower joints scraped during the final clean, we can help. Searching for sealant specialists in Bockmer End? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.

Sites around smaller places like Bockmer End can be a fair drive from suppliers, so we come with everything the package needs, timed to the stage the job has reached. Send drawings or photographs and the programme and we will quote to suit.

Every job we finish is backed by a 12-month workmanship guarantee, in Bockmer End as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Bockmer End: questions and answers

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

Yes, hospitals are one of the sectors we cover. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Is Bockmer End too far out for you?

No. Small places get the same service as large ones. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.

Is it fine to apply new sealant on top of old?

No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

What happens if old sealant might contain asbestos?

Managing asbestos is the dutyholder’s responsibility, so for older buildings we ask for the asbestos register first. If anything suspect turns up, we stop until it’s tested.

Do you offer coloured sealant?

It depends on the product. Some ranges offer many colours, others very few, so we will confirm the colours available for the specified product with the quote.

Do you need to see the site first?

That depends on the size and complexity of the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs normally get a visit.

How many days will you need on site?

The duration is planned around your programme and the access we’re given. We’ll give you an estimate of time on site when we quote.

Surface by surface

Fire-rated sealant where specified

Not every penetration suits a sealant. 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

Across a block of flats or a hotel, sanitary sealing is repeated in every room. A single team keeps the standard consistent.

What we’re called out for in Bockmer End

A new building moves while it dries and settles. Plaster, screeds, timber and blockwork all shrink as they lose moisture and internal caulk in a moving joint is normally the first to crack. Choosing the right product for each joint reduces that.

Site and facilities staff are often the first to spot these:

  • Sanitary sealant damaged by following trades
  • Inconsistent sealant finishes from plot to plot
  • Old sealant on a refurbishment that needs stripping before new work
  • Cracks opening in caulked internal joints

When a school such as Danesfield School is extended or refurbished, the mastic package is often squeezed into the holidays.

Comparing quotes

  • Proof of insurance
  • How long is the guarantee, and what does it include?
  • Will failed sealant be removed rather than covered?
  • Are they CHAS accredited or on Constructionline?

Our contractor checklist

What sets the cost

To price the job, we consider:

  • Which sealant the job calls for
  • Backing rod, priming and other preparation
  • How accessible the joints are
  • The total length or number of joints

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Mention the access as part of your enquiry.

Before you send an enquiry

However big the job, these details speed things up:

  • Photos of the joints, close up and from further back
  • How the joints are reached, and at what height
  • Specification clauses that apply
  • Approximate linear metres or a joint schedule

Send us photographs, drawings or a joint schedule are often enough for a fixed quote. If the job needs a look first, we will arrange a site visit.

Building owners, agents and FMs in Bockmer End

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

When to bring in a specialist

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Some joints are best left to specialists: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong normally costs more in the end than doing them right.

Sites and facades in and around Bockmer End

Central London is about 32 miles from Bockmer End. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and each scheme needs its mastic sealed to programme. The South East is one of the drier parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so the external programme keeps a little slack.

Historic houses such as Harleyford Manor (to the south-east of Bockmer End) are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. For a contractor at a hotel such as Danesfield House Hotel And Spa, under half a mile south-east of Bockmer End, the mastic often has to be finished before a reopening date.
