Commercial sealant contractors for Walton-on-Thames sites

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

What sealant work can’t fix

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • A dripping trap, valve or pipe behind a fitting
  • A failed roof covering or waterproofing membrane
  • Cracking that needs a structural engineer to look at it

If you’re not sure, just ring 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer before you book.

Where we work in Walton-on-Thames

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

About our commercial sealant contractors in Walton-on-Thames

On a commercial site, sealant turns up in more places than people expect: washroom fittings, kitchen worktops, window boards, partition heads and the line where floors meet walls. Externally it keeps rain out of frame perimeters, panel joints and movement joints. We deal with internal and external sealant joints alike, matching the sealant to the location instead of using one product throughout. If you have external beads that have gone brittle and cracked and messy, uneven beads from earlier work that let the building down, we can help, on external facade joints, window and door perimeters and washrooms and tea points alike. Searching for sealant specialists in Walton-on-Thames? We have been sealing commercial buildings since 2005.

Occupied buildings in Walton-on-Thames need the work phased: washrooms in turn, floors in sections and entrances kept open.

In a town the size of Walton-on-Thames, commercial buildings tend to be high-street shops, offices over shops, schools, care homes and small industrial units. Shopfronts, kitchens, washrooms and frames all have sealant that ages, and where a frontage is on show, a matched colour keeps it looking right.

We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application.

On site: what to expect

Inspect, seal, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. For a town like Walton-on-Thames, we try to group jobs for the same client into one visit. Tell us when the building is open and we’ll plan to suit.

  1. You send photographs, drawings or a list of the joints and areas involved.
  2. The failure is diagnosed and a fixed quote issued for the work agreed.
  3. Before anything is cut out, we agree access, timings and sequence.
  4. We strip the failed bead and prepare both faces of the joint.
  5. Backing and primer go in where needed, then the chosen sealant is applied and tooled.
  6. We walk the completed areas with you and sign them off under the 12-month guarantee.

Getting the site ready

  • Send any specification or drawings in advance
  • Share your working hours and any access restrictions
  • For older buildings, check the asbestos register before work

Advice

For managing agents and facilities managers

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.

Questions we are asked in Walton-on-Thames

Must a hotel around Walton-on-Thames close while you work?

Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. Housekeeping and our team agree each day’s rooms.

Can you match sealant colours for premises in Walton-on-Thames?

Yes, we can typically get close to most finishes from the product’s colour range. The quote lists the colours the product is made in.

Is failed sealant stripped out, or sealed over?

Every failed bead is cut out completely. Laying new silicone on old gives it nothing to grip.

How do we get a quote?

Send what you have, even a few photos and rough lengths. Questions or a site visit follow where needed.

When is resealing likely to be due?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

Does weather matter for sealant work?

It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so external work may be moved if conditions aren’t right. Internal work is far less affected.

What guarantee do you give on resealing?

Our workmanship is guaranteed for 12 months. Public liability insurance is in place too.

How the job changes by surface

Fire-rated seals where specified

Fire-rated sealant is only one type of fire-stopping product. Other products, such as collars, wraps and batts, are specified for different services.

Washrooms and toilets

Around WCs, urinals, vanity tops, IPS panels and cubicles, sealant is wet most of the day. Old sealant comes out and a sanitary silicone with anti-mould additives goes in.

Looking after the joints

Keep the joints in good shape with a few simple steps:

  • On pre-2000 buildings, share the asbestos information before work starts
  • Log reseals in the O&M or maintenance records
  • Act on the first lifting edges rather than waiting
  • Look at the sealant around anything that has been moved or replaced

Brief your cleaning team on the joints that have been resealed. Abrasive pads, scrapers and some strong chemicals damage sealant surfaces, while a neutral cleaner and a soft cloth do no harm.

An open joint in a food area or toilet collects dirt and moisture that cleaning can’t reach. Environmental health officers look at how cleanable surfaces are, which makes sound joints worth keeping on top of.
