Commercial sealant contractors across Preston Bissett

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

After the work

Problems stay small when the joints are checked regularly. Specifically:

  • Deal with small splits before they become leaks
  • Add sealant to the planned maintenance inspection list
  • Ask fit-out and M&E contractors to report any sealant they disturb
  • Keep a record of which joints were resealed and when

Our workmanship on each job is backed by a 12-month guarantee. File the handover note with the building records so it’s easy to find if a joint we sealed gives trouble inside the 12 months.

Sealant rarely fails all at once across a building. A few splits this year usually mean more next year. We can assess the lot and suggest what to do now and later.

A reseal stands or falls on the preparation underneath it. Old silicone gives new sealant nothing to grip, so every trace of it is removed and the faces are cleaned until they’re sound and dry, with no dust or grease left. Primer is used wherever the manufacturer calls for it on that surface and the joint depth is controlled with backing rod. We work on window and door perimeters, floor and threshold joints and washrooms and tea points, and what we’re called in for most is mouldy silicone around WCs, urinals and vanity tops and messy, uneven beads from earlier work that let the building down. Facilities teams, main contractors and managing agents in Preston Bissett tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

Occupied buildings in Preston Bissett need the work phased: washrooms in turn, floors in sections and entrances kept open.

Rural business units near smaller places such as Preston Bissett are frequently converted agricultural buildings. Old masonry beside new aluminium, timber and plasterboard gives plenty of joints between materials that move differently, and a sealant colour that suits the building’s character is often part of the brief.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Doing it in-house

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

Common problems we fix in Preston Bissett

A split down the middle of the bead tells a different story. That usually means the joint stretched further than the product could cope with. Replacing it like for like rarely holds.

Any of the following is a good reason to get the joints checked over:

  • External beads that have gone brittle and cracked
  • Wall and floor joints that have lost their seal
  • Messy, uneven beads from earlier work that let the building down
  • Frame sealant that has cracked, shrunk or pulled away

Industrial estates such as Three Bridge Mill Industrial Park, 2.1 miles south-east of Preston Bissett, have offices, trade counters and welfare areas whose sealant ages like any other building’s.

Comparing quotes

  • Will failed sealant be removed rather than covered?
  • Can the work be phased to keep areas open?
  • Is the sealant right for the movement and the substrate?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?

Choosing a commercial sealant contractor

Quoting for work in Preston Bissett

We price every job individually. The things that drive the figure:

  • The site’s rules and procedures
  • How much existing material needs removing
  • Distance, for remote addresses
  • Specialist products, such as fire-rated or hygienic sealants

There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote and we’ll price your job on its own details.

Sending details for a quote

Whether it’s one area or a whole building, these details speed things up:

  • Specification clauses that apply
  • Anything awkward about access or site hours
  • The asbestos register, for older buildings
  • Photos of the joints, close up and from further back

Need a figure for a tender or a budget? Send the scope and any drawings, and we’ll return a fixed quote that you can work with. For a chat about it beforehand, ring 01277 525 020 or email a schedule or drawings.

Our process

Tell us your site hours and access windows and we’ll plan around them. While we’re working, the area stays contained and tidy, and we check in with your contact before moving on to each new area. Rural sites near Preston Bissett may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.

  1. Site photographs, drawings or a visit tell us what’s there and how it has failed.
  2. You get a fixed quote covering removal, preparation and the new sealant.
  3. Sequence, access and working times are settled before the first joint is touched.
  4. Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
  5. Depth is set with backing, then the sealant is applied, tooled and the area tidied.
  6. Completed areas are signed off with you under our 12-month guarantee.

What we need from you

  • Move anything stored against the joints
  • Tell staff and tenants when we’ll be in
  • Share your working hours and any access restrictions

Getting a fixed quote

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. For smaller jobs, photos and a description will do.

When it isn’t the sealant

Honesty saves time and money. New sealant won’t cure:

  • Misted, cracked or failed glazing units (a glazier’s job)
  • Roof leaks that only look like a joint problem
  • Structural cracks or movement the joints weren’t designed for

If in doubt, phone 01277 525 020 or email a schedule or drawings and we’ll say what we think before you book.

Surfaces we seal

  • Movement joints in walls and floors
  • Floor and threshold joints
  • Kitchen worktops and splashbacks
  • Window and door perimeters
  • External facade joints
  • Washrooms and tea points

Questions about Preston Bissett

Is Preston Bissett off your patch?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Good photographs up front let us bring everything on the first visit.

Can you work at a site such as Three Bridge Mill Industrial Park, by Preston Bissett?

Yes. Our area takes in Preston Bissett and its surroundings, with estates and business parks such as Three Bridge Mill Industrial Park included. To start, just speak to us on 01277 525 020 or use the quote form with the unit, the joints involved and your access times.

What do you need from us to quote?

Photos, drawings or a schedule of the joints are usually enough to start through our quote form. Where we need to see it, we will arrange a site visit, then send a fixed quote.

What about asbestos in old mastic?

Some older mastics did contain asbestos. That’s why we ask for the asbestos information first, and stop if a material is suspect until it’s tested.

What site paperwork can you provide?

Let us know your requirements when you ask for a price, and we will confirm the RAMS, insurance and CSCS details with the quote. For older buildings we will ask for the asbestos register, plus your site induction rules.

Can areas stay open during the work?

That comes down to planning: areas are phased, access windows agreed and enough washrooms or entrances left in use. Tell us what has to stay open and we will plan the job around it.

Can you work to our specification?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and any queries are raised before we start.
