Commercial sealant contractors in Lewiston

Most of the buildings we seal stay open while we are there. Tell us your site hours and access windows and we will plan around them. It’s the same approach in offices, retail units, hotels, schools and healthcare buildings. We work on floor and threshold joints, washrooms and tea points and window and door perimeters, and the usual reasons a site gets in touch are a top-up bead over failed sealant, now lifting and messy, uneven beads from earlier work that let the building down. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Lewiston, preparation and product choice get the time they need.

The most common commercial job in Lewiston is resealing joints that have simply reached the end of their life: split, chalky or peeling, with leaks or mould starting behind it.

For work in and around Lewiston, we’d rather do everything on one trip, so it helps to have photographs and a full list first. Several jobs nearby can also be put together.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Common questions from Lewiston clients

Does a hotel in Lewiston need to shut while its sealant is renewed?

In the majority of cases no closure is needed: we work room by room or floor by floor. We agree the order of rooms and the timings with you before we start.

Is Lewiston too far out for you?

Not at all. Lewiston is within our area. Every Scottish council area is within our area. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

When is resealing likely to be due?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

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

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

What about asbestos in old mastic?

In buildings from before 2000 in particular, some old mastics and sealants may contain asbestos. Before cutting anything out, we ask for the asbestos register or survey, and anything suspect is left until it has been tested.

How do we get a quote?

Photos, drawings or a schedule of the joints are typically enough to start. If a visit is needed we will book one, and a fixed quote follows.

Can weather delay the job?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

What the job involves on each surface

Commercial kitchens and tea points

Kitchen joints along worktops, sinks, splashbacks and wall cladding collect grease and moisture. Proper degreasing comes before any new sealant.

Fire-rated seals where specified

Intumescent and other fire-rated sealants go in at service penetrations and linear gaps to the maker’s tested details, where they are specified. Fire-stopping design and sign-off sit with the designer, fire engineer or building control, and we install to the specification.

Honest limits

Part of a good diagnosis is knowing where sealant stops. We will tell you if the real problem is any of the following:

  • Suspect materials that need testing and specialist removal
  • Faulty windows rather than failed perimeter sealant
  • Leaks from pipework, wastes or valves (that’s plumbing)

Not sure which it is? You can give us a call on 01277 525 020 or send details through our quote form and we will tell you honestly.

What we seal

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

Commercial sealant contractors in Lewiston: the local picture

There are a number of hotels within about 2 miles of Lewiston. In hotels, sealant shows everywhere, from bathroom joints to reception counters, so colour and a clean finish matter; work is planned so the hotel keeps trading. Being in the west of Scotland, Lewiston gets more rain than eastern areas. External joints are sealed on dry days, with some flexibility in the dates. Weather-facing frames tend to need resealing before the sheltered ones

Whatever the building in Lewiston, commercial sealant work starts with cutting out the failed bead and cleaning the joint back to sound material. A hotel such as Benleva Hotel (less than half a mile north-east of Lewiston) shows how much sealant a hospitality building has on show, from bathroom joints to the bar.

Lewiston is about 13 miles south-west of Inverness, in Highland. Our applicators travel to Lewiston for work on sealant joints, handled exactly as we handle every other area. We work across 256 places in Highland, from busy centres to rural villages.

Commercial sites across IV63 are covered for sealant joints. Streets here include Dal of Borlum, Carn Glas and Carriers Croft, and sites on any of them can send details for a fixed quote. We also cover Drumnadrochit (1 mile north), Torness (4 miles east), Gorthleck (6 miles south), Dores (7 miles north-east) and Kiltarlity (8 miles north) for sealant joints. Nearby towns on our patch include Inverness (13 miles north-east), Merkinch (14 miles north-east), Hilton (13 miles north-east), Crown (14 miles north-east), Millburn (14 miles north-east) and Muir of Ord (13 miles north). For island and remote sites, travel and materials need planning ahead, so include the location in your enquiry.

Near you in Lewiston

Aftercare for building managers

For the best life from the joints:

  • Don’t let cleaning or traffic back on before the cure time is up
  • Make sure ventilation in wet areas is switched on and working
  • Report cracked or peeling sealant early
  • Check the asbestos register before anyone disturbs old sealant in an older building

Good ventilation keeps wet-area sealant in better condition. Extraction that isn’t working keeps the joints wet, and mould follows damp. It’s worth having fans checked while the sealant is fresh.

Tenants and staff spot black or split sealant quickly, and it reflects on how the building is run. Replacing it on a planned cycle keeps complaints down.

How the quote is worked out

Before we quote, we look at:

  • How much existing material needs removing
  • How accessible the joints are
  • The total length or number of joints
  • Working within restricted access windows

Pricing sealant joints depends on how many there are, their condition and the access, and any specification that applies. Call for a quote.

Details that help us quote

We can often quote from photographs and a few details. It helps to include:

  • How the joints are reached, and at what height
  • Any specification or named product
  • The asbestos register, for older buildings
  • The type of building and who uses it

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to ring 01277 525 020 or send photos by email with what you know.

From enquiry to sign-off

Inspect, seal, sign off: that’s the shape of every visit. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. Travel to smaller Scottish places like Lewiston is planned so the job is finished in one visit where possible, which is why we ask for photos and a full list first. Outside work also needs a suitable weather window.

  1. Send details through our quote form, or ask for a site visit.
  2. The cause is diagnosed and the scope priced as a fixed quote.
  3. Work is phased around your occupiers where areas need to stay in use.
  4. Every failed bead is removed rather than covered.
  5. A suitable product for each joint goes in at the right depth and is tooled.
  6. A final walk-round, then the 12-month guarantee applies.

What we need from you

  • Explain the parking and delivery arrangements
  • Tell us what induction or permit system the site runs
  • Clear stock, furniture or equipment away from the joints

Advice

General trades versus a specialist

Redoing a failed joint normally costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

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.
