Sealant specialists in Dallington

Commercial occupiers rarely want a floor out of action for sealant work. Tell us your site hours and access windows and we’ll plan around them; phasing keeps some washrooms, kitchens or entrances available while others are done. That applies whether the building is an office, a shop, a hotel, a college or a care home. If you have external beads that have gone brittle and cracked and earlier reseals applied straight onto the failed bead, we can help, whatever the surface. Most enquiries from Dallington start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Occupied buildings in Dallington need the work phased: we agree the order with you and hand back each area with its cure time.

Business units in the countryside around places like Dallington are often converted barns, stables or farmyards. Old masonry beside new aluminium, timber and plasterboard gives plenty of joints between materials that move differently.

Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Your questions answered

Is a smaller place like Dallington outside your area?

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

Do you offer colour-matched sealant for buildings in Dallington?

Yes. Colour matching to frames, cladding, stone and shop-fit finishes is a regular part of the work. The quote lists the colours the product is made in.

Is your work guaranteed?

It’s backed by our 12-month guarantee. Should anything we did fail within that period, let us know.

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.

Can weather delay the job?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

How is commercial sealant work priced?

Start with whatever information is to hand. Questions or a site visit follow where needed, then a fixed quote.

Is it OK to apply fresh sealant over existing beads?

Removal comes first, every time. Then the joint is cleaned, primed where the maker specifies, backed to depth and resealed.

For managing agents and facilities managers

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Sites in Dallington can sit alongside others in a wider programme.

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

Diagnose, treat, sign off

Where the site stays busy, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before the next one starts. If others near Dallington need work, visits can be combined, which keeps travel down. You will have a fixed quote before work starts.

  1. You send photos, drawings or a list of the joints and areas involved.
  2. We work out why the joints have failed and fix a quote for the agreed scope.
  3. We plan around your site hours and access windows, phasing the work where areas have to stay in use.
  4. The failed bead is removed and the joint faces cleaned until they’re sound and dry.
  5. The depth is set, primer is used where the maker calls for it, and the fresh bead is applied and tooled.
  6. Finished joints are checked with you and handed over with our 12-month guarantee.

What we need from you

  • Flag any permit to work we’ll need
  • Have the specification and drawings to hand
  • Send asbestos survey details if the building is pre-2000

When to call us in Dallington

No sealant joint is permanent. Its life comes down to movement, UV and weather, how it’s cleaned, how much traffic passes it and what was used in the first place. On a busy commercial site several of those pile up at once.

These are often picked up first by site or facilities staff:

  • Gaps behind commercial kitchen worktops and sinks
  • Damp patches where an external joint has failed
  • Frame mastic that has hardened and come away from the wall
  • External beads that have gone brittle and cracked

Colour matters on frontages and fit-outs, so the quote confirms which colours the chosen product comes in.

Questions to ask before you book

  • The named product and why it was chosen
  • Their pre-qualification and accreditations
  • Do they follow the manufacturer’s priming guidance?
  • How long is the guarantee, and what does it include?

Our contractor checklist

General trades versus a specialist

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.

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

What sealant work can’t fix

Some faults sit outside our scope, and we point that out rather than sealing over them:

  • Leaks from pipework, wastes or valves (that’s plumbing)
  • Structural cracks or movement the joints weren’t designed for
  • Roof leaks that only look like a joint problem

If in doubt, give us a call on 01277 525 020 or email the details over and we will say what we think before you book.

Where we work in Dallington

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

Cost factors for sealant joints

Quotes vary with the job. It mainly depends on:

  • The site’s rules and procedures
  • How accessible the joints are
  • Joint width, depth and condition
  • Quantities, in metres or numbers

The price depends on how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a fixed quote when you are ready.

Before you send an enquiry

A few photos plus some basic facts will normally do. It helps to include:

  • Photos of the joints, close up and from further back
  • Whether the building will be occupied during the work
  • Drawings or a marked-up plan, if available
  • The product your specification calls for

Pricing a project or setting a maintenance budget? We’ll quote against your scope and drawings you can plan around. For a chat about it beforehand, call 01277 525 020 or email drawings and photos.
