What Stone Hill’s businesses ask us to seal

Stone Hill sits in one of the drier corners of the country, the South East. External joints still need dry faces and the right temperature, and damp or frosty mornings can hold work up. Stone Hill lies roughly 54 miles out from central London. Business parks and retail centres are common around the capital’s motorway corridors. Multi-site occupiers here often want one sealant contractor across all their buildings.

Premises within reach of Westenhanger station (to the south-east of Stone Hill) often have busy frontages where joints are seen by everyone passing. A business with units at Evegate Business Park and Mersham-le-Hatch Business Village needn’t use two contractors for its sealant. If you run an office at a site such as Evegate Business Park (1.4 miles west of Stone Hill), the sealant at reception desks, tea points and frames ages with each fit-out.

Stone Hill is about 5 miles north-west of Hythe, in Kent. We cover Stone Hill and the rest of Kent, with the same fixed quotes and 12-month guarantee as everywhere else. 931 places across Kent fall within our area, including Stone Hill. For work in that direction, see our Brighton page (52 miles or so).

Business premises anywhere in TN25 are within our area. Buildings on Stone Hill, Southenay Lane and Cooper's Lane are within our area for sealant joints. If your building is just outside Stone Hill, we cover Lilyvale (1 mile north-west), Brabourne Lees (1 mile north-west), Smeeth (1 mile north-west), Ridgeway (1 mile north-west) and Bircholt Forstal (2 miles north). Further afield, our area takes in Ashford (6 miles west), Canterbury (12 miles north), Dover (14 miles east), Folkestone (8 miles east), Faversham (15 miles north) and Hythe (5 miles south-east).

Commercial mastic work in Stone Hill

On a commercial site, sealant turns up in more places than people expect: around sanitaryware, along worktops and splashbacks, at window boards, partition heads and floor junctions. 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’re dealing with weathered facade sealant that no longer flexes and leaks that seem to come through a sealant line, we can put it right, whatever the surface. Facilities teams, main contractors and managing agents in Stone Hill tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

A lot of what we do in Stone Hill is replacing sealant that has done its years: split, chalky or peeling, with leaks or mould starting behind it.

In and around smaller places such as Stone Hill, the commercial buildings we are asked about are often pubs, shops, village halls and barns converted to offices. Each has kitchens, washrooms and frames whose joints need renewing in time.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

Your questions answered

Is a smaller place like Stone Hill outside your area?

Not at all. Stone Hill is within our area. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.

Do you offer colour-matched sealant for buildings in Stone Hill?

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

How do we get a quote?

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

Which site documents can you send us?

Send your site requirements with the enquiry. From you, we will need the asbestos information for older buildings and any site rules.

Can weather delay the job?

For external joints, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

Is it OK to apply fresh sealant over existing beads?

The old bead is stripped out first. Then the joint is cleaned, primed where the maker specifies, backed to depth and resealed.

Could the old sealant in an older building contain asbestos?

Some older mastics did contain asbestos. That’s why we ask for the asbestos information first, and stop if a material is suspect until it’s tested.

What affects the price in Stone Hill

To price the job, we consider:

  • Travel to remote or island sites
  • Working within restricted access windows
  • The product specified
  • Any access equipment needed

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote and we will put a fixed figure on it.

Details that help us quote

Good information means a firmer quote. Helpful details to send:

  • Whether an asbestos survey exists
  • Clear photos of the problem areas
  • The site address and postcode
  • Rough lengths or quantities, or drawings if you have them

Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. The easiest way is to speak to us on 01277 525 020 or use the quote form.

Doing it in-house

Redoing a failed joint normally costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

A short, simple internal joint is often within reach of a maintenance team. 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.

What the job involves on each surface

Shop fronts and retail fit-outs

In retail, sealant is on show. Counters, display units, shopfront frames and floor trims all need a neat line, frequently colour-matched to the fit-out. We will confirm the colours available for the specified product.

Fire-rated seals where specified

Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the product’s tested detail. Fire-stopping design and sign-off sit with the designer, fire engineer or building control; we install what’s specified.

Owners, agents and contractors

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Stone Hill can form part of a wider programme.

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, with CSCS-carded applicators on site.

When something else is needed

A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is any of the following:

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

If in doubt, give us a call on 01277 525 020 or use the quote form and we will say what we think.

Joints and surfaces we work on

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

From enquiry to sign-off

Site rules come first: signing in, inductions and any permit to work. 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. Jobs in and around smaller places like Stone Hill are typically planned as a single visit, so photos and measurements up front really help. That way the right products come on the day.

  1. First, details reach us through the quote form or 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.

Before we start on site

  • Tell staff and tenants when we’ll be in
  • Send your site hours and access windows
  • Point out any areas we must not close
