Sealant on show in Ashford’s commercial buildings

Central London is about 48 miles from Ashford. This part of the South East is dense with business parks and out-of-town offices. Multi-site occupiers here often want one sealant contractor across all their buildings. The 2 miles around Ashford include two care or nursing homes. Care homes need tidy, cleanable joints in kitchens, corridors and communal rooms, often in colours that suit the décor.

Shops and cafés around stations like Ashford International station (to the north-east of Ashford) trade from early, so work is timed around them. If you look after units at a retail site such as Gallagher Retail Park, less than half a mile to the south-east of Ashford, shopfront perimeters and shop-fit joints are where a matched colour shows.

Sealant specialists in Ashford

Inside a commercial building, sealant does a lot of quiet work: around sanitaryware, along worktops and splashbacks, at window boards, partition heads and floor junctions. Outside, it closes facade joints, frame perimeters and movement joints against the weather. We deal with internal and external sealant joints alike, matching the sealant to the location instead of using one product throughout. We work on floor and threshold joints, washrooms and tea points and movement joints in walls and floors, and the usual reasons a site gets in touch are mouldy silicone around WCs, urinals and vanity tops and a top-up bead over failed sealant, now lifting. Most enquiries from Ashford start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

In an occupied building in Ashford, the job is planned so areas stay in use: washrooms in turn, floors in sections and entrances kept open.

A large place such as Ashford tends to have every kind of commercial building: business parks, retail centres, hotels, surgeries and offices above the high street. That variety is why a single contractor covering several premises can help, with colours kept consistent site to site where a brand needs it.

The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Leave it or put it right?

A failed seal around a window, worktop or panel doesn’t mean the element itself has to go. Often the fitting is sound and the joint is the only thing letting it down. Resealing typically costs far less than renewal. On a busy site in a large place like Ashford, a failed joint gets worse with every day of use. Acting early keeps it a sealant job.

There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

Why choose Mastic Doctor in Ashford

  • Colours chosen to suit frames, cladding or finishes where possible
  • Constructionline member for supplier checks
  • Over 20 years of commercial sealing
  • Products installed to the manufacturer’s instructions

Take a look at our cost guide and our accreditations.

Common problems we fix in Ashford

If sealant tears through its centre, it has failed cohesively. That typically means the joint stretched further than the product could cope with because the bead was too thin, the joint over-stretched or the movement class wrong. Replacing it like for like rarely holds, so width, depth and product are checked before we quote.

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

  • Gaps behind commercial kitchen worktops and sinks
  • Messy, uneven beads from earlier work that let the building down
  • Hardened, chalky sealant on south-facing or exposed elevations
  • Wall and floor joints that have lost their seal

For a hotel such as Castle Hotel, which lies north of Ashford, the colour of a joint at the bar or the bath matters to the look of the room.

How to choose a sealant contractor

Surface by surface

Shop fronts and retail fit-outs

Retail work usually has to fit around trading. We plan around the access windows the store gives us.

Window and door perimeters

Internally, window boards and frame edges often have decorators’ caulk or silicone that has cracked. The product depends on whether the joint will be painted.

Doing it in-house

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.

Redoing a failed joint usually 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.

Aftercare for building managers

Your facilities or cleaning team can help the joints last. Share these points with them:

  • Check the asbestos register before anyone disturbs old sealant in an older building
  • Respect the cure time before reopening an area
  • Add sealant to the planned maintenance inspection list
  • Keep abrasive pads and scrapers off resealed joints

Let your cleaning contractor know what’s new. Abrasive pads, scrapers and some strong chemicals damage sealant surfaces, while a neutral cleaner and a soft cloth do no harm.

Movement joints that fill with debris stop working. The joint can no longer close, so its edges crack or spall. At that point it’s a repair job rather than a reseal.

From enquiry to sign-off

Site rules come first: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. Bigger buildings in Ashford are usually done in phases agreed with the site or facilities manager, keeping disruption low. Photos and drawings let us propose a sequence with the quote.

  1. We begin with whatever information you have, whether that’s photographs, a drawing or a list of locations, and a site visit is booked where it helps.
  2. Next comes a diagnosis and a fixed quote.
  3. Before anything is cut out, we agree access, timings and sequence.
  4. Failed sealant is cut out and each joint cleaned back to sound, dry faces.
  5. The depth is set, primer is used where the maker calls for it, and the fresh bead is applied and tooled.
  6. Each area is inspected, signed off and backed by our 12-month guarantee.

Before we start on site

  • Explain the parking and delivery arrangements
  • Tell staff and tenants when we will be in
  • For older buildings, check the asbestos register before work

Your questions answered

Must a hotel around Ashford close while you work?

Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. The plan is built around your bookings.

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

Yes. Colour matching to frames, cladding, stone and shop-fit finishes is a regular part of the work. Available colours for the product are confirmed with the quote.

Do you check for asbestos before removing sealant?

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 if something is suspected, work stops until it’s tested.

Can weather delay the job?

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.

Will your applicators have CSCS cards?

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

When is resealing likely to be due?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

Do you work in Ashford?

Yes. We cover Ashford and the rest of Kent. To discuss a job, ring 01277 525 020 or email a schedule or drawings.
