Commercial sealant contractors for commercial buildings in Westwell

On older buildings, particularly those put up before 2000, some old mastics and sealants may contain asbestos. Before anything is cut out, we ask for the asbestos register or survey, because the duty to manage asbestos sits with the dutyholder. Anything suspect is left alone until it has been tested. We work on external facade joints, window and door perimeters and kitchen worktops and splashbacks, and what we’re called in for most is greasy, split joints in a kitchen or tea point and expansion joints with the sealant torn out. Searching for sealant specialists in Westwell? Mastic Doctor has worked for contractors, FMs and building owners since 2005.

Quotes for commercial sealant in Westwell can come from photographs and a joint schedule, or from a walk-round, and the scope is set out in writing.

Commercial sealant work around smaller places like Westwell tends to mean pubs and restaurants, halls, farm shops and offices in converted farm buildings. Each has kitchens, washrooms and frames whose joints need renewing in time.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Commercial premises in Westwell

The area within 2 miles of Westwell holds several hotels. A hotel refurbishment is full of joints that guests will see, and a matched colour keeps them discreet; work is planned so the hotel keeps trading. At about 46 miles from central London, Westwell is within reach of the capital. The commuter belt holds a great many offices, retail parks and business parks. Occupiers with several premises in the region tend to prefer one contractor and one point of contact.

Shops and cafés around stations like Charing station (to the north-west of Westwell) trade from early, so work is timed around them. If you run an office at a site such as Eurogate Business Park (2.3 miles south-east of Westwell), the sealant at reception desks, tea points and frames ages with each fit-out. Sites a few miles apart, such as Eurogate Business Park and Warren Retail Park, can share one programme and one point of contact.

Westwell is about 4 miles north of Ashford, in Kent. Across the TN25 postcode area, the process is the same: send details, get a fixed quote, we seal, and the work is guaranteed. 931 places across Kent fall within our area, Westwell among them. We also cover London, around 46 miles from Westwell.

From enquiry to sign-off

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Jobs in and around smaller places like Westwell are usually planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. Send details through our quote form, or ask for a site visit.
  2. We diagnose the cause of failure and price a fixed scope.
  3. Work is phased around your occupiers where areas need to stay in use.
  4. Every failed bead is removed rather than covered.
  5. Each joint gets a suitable sealant, laid to depth and tooled.
  6. We check the work with you, and the 12-month guarantee starts.

Questions we’re asked in Westwell

Must a hotel around Westwell close while you work?

Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. Tell us your quiet periods and access windows and we’ll plan around them.

Can you work at a site such as Eurogate Business Park, by Westwell?

Yes, sites like Eurogate Business Park are within our area, along with the rest of Westwell. To start, just speak to us on 01277 525 020 or send photos by email with the unit, the joints involved and your access times.

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.

Do your applicators hold CSCS cards?

Yes. Our applicators hold CSCS cards, which many sites require.

How long does a job like this take?

It depends on the scope, but the work normally takes anything from part of a day on a short run of joints to several weeks on a large phased package. Larger or phased jobs take longer, and we will give you a timescale with the quote.

Will you just go over the old sealant?

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

How long do sealant joints last?

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.

What the job involves on each surface

Washrooms and toilets

Washroom joints take water, cleaning chemicals and constant use. Old sealant comes out and a sanitary silicone with anti-mould additives goes in, with phased work so some facilities stay open.

Shop fronts and retail fit-outs

Shop fits put sealant right in front of clients. Joints around counters, displays and shopfront frames have to look tidy as well as seal, frequently colour-matched to the fit-out. Colour options are confirmed with the quote.

Leave it or put it right?

It can be tempting to hold sealant work back until the next refurbishment. For internal joints that are only cosmetic, that can make sense, but a joint letting water in now keeps doing damage until the refurb arrives. Splitting the scope into now and later is often the sensible compromise. Older rural buildings around Westwell move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

What affects the price in Westwell

Your fixed quote is built from the real scope. It allows for:

  • Specialist products, such as fire-rated or hygienic sealants
  • The size and state of each joint
  • Distance, for remote addresses
  • Quantities, in metres or numbers

What a job costs comes down to how many linear metres there are, what has to come out first and how the joints are reached. Call for a fixed quote once you have the details.

Before you send an enquiry

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

  • Any dates the work must fit around
  • What the building is and how it’s used
  • Asbestos survey details if the building is older
  • Specification clauses that apply

Send details, get a quote, we seal, guaranteed: that’s how every job runs. The first step is to call 01277 525 020 or use the quote form with what you know.

Site staff or a sealant 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.

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
