Questions about Boxley

Is Viewpoint Industrial Estate, near Boxley, within your area?

Yes, sites like Viewpoint Industrial Estate are within our area, along with the rest of Boxley. Photos and a short description are enough for a first look.

Will our hotel in Boxley need to close for the work?

In the majority of cases no closure is needed: we work room by room or floor by floor. Tell us your quiet periods and access windows and we will plan around them.

Does weather matter for sealant work?

Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

When can the area be used after sealing?

That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.

Can areas stay open during the work?

Phased work can be planned so areas stay in use. Tell us your site hours and access windows and we’ll plan around them.

Will your applicators have CSCS cards?

Yes. If you need card details for site access, let us know and we’ll send them with the quote.

Which sealant will you use?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

How we handle commercial sealant contractors in Boxley

We’ve applied sealant on commercial sites for over 20 years: we are CHAS accredited and a Constructionline member, our applicators hold CSCS cards, and we carry five million pounds of public liability insurance. Let us know which site documents you need and they’ll be confirmed with the quote. The enquiries we see most involve damp patches where an external joint has failed and sanitary sealant that has gone black and patchy, across external facade joints, kitchen worktops and splashbacks and window and door perimeters. A specialist sealant contractor works differently from a general builder: in Boxley, that means joint design, primers and backing rod as standard.

Occupied buildings in Boxley need the work phased: washrooms in turn, floors in sections and entrances kept open.

Commercial sealant work around smaller places like Boxley 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.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

When it isn’t the sealant

Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:

  • A failed roof covering or waterproofing membrane
  • Water from a services leak rather than a joint
  • Cracking that needs a structural engineer to look at it

If in doubt, call the office on 01277 525 020 or use the quote form and we’ll say what we think before you book.

Surfaces we seal

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

Quoting for work in Boxley

Each job is priced on its own details. The main factors are:

  • How much there is to seal
  • Access and working height
  • Whether the work must be split into stages
  • The site’s rules and procedures

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.

Details that help us quote

It doesn’t need to be a full survey. A few details are enough to get going:

  • Approximate linear metres or a joint schedule
  • The asbestos register, for older buildings
  • The type of building and who uses it
  • The site address and postcode

A handful of photos and a postcode is the fastest way to a quote. Upload them with the quote form, or call the office on 01277 525 020 or email the details over if you’d rather talk the job through.

Why deal with it now?

Before budgeting for new frames, cubicles or worktops, check whether it’s just the sealant. Often the fitting is sound and the joint is the only thing letting it down. Resealing normally costs far less than renewal, and we’ll say so if the frame or fitting is life-expired. Around Boxley, it’s better to renew all the failing joints at once. Send photographs of each area and we’ll quote for the lot.

No two sites price the same: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Work for main contractors and building owners

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. We can agree access arrangements and keyholder contacts beforehand.

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Boxley can sit alongside others in a wider programme across Kent.

Our process

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. Jobs in and around smaller places like Boxley are typically planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. We start with the evidence: photos, drawings or a look on site.
  2. You get a fixed quote covering removal, preparation and the new sealant.
  3. Sequence, access and working times are settled before the first joint is touched.
  4. The failed sealant comes out and the faces are prepared, with primer where required.
  5. Depth is set with backing, then the sealant is applied, tooled and the area tidied.
  6. We hand back each area with its cure time and our 12-month guarantee.

What we need from you

  • Point out parking and an unloading spot
  • Tell us your opening times and when work is allowed
  • Clear stock, furniture or equipment away from the joints

Getting a fixed quote

Let us know the site, the scope and your timescale, and a fixed quote will follow. To get it moving, ring 01277 525 020 or email drawings and photos.

Advice

What we are called out for in Boxley

Plenty of failed joints were never sealed with the right product. Decorators’ caulk on a joint that moves, acetoxy silicone on stone or metal, or a stiff sealant on a facade will all fail early. BS 6213 gives guidance on choosing construction sealants, and many specifications refer to it.

If one of these sounds familiar, it’s time for a closer look:

  • Leaks that seem to come through a sealant line
  • Layers of sealant, all of them failing
  • Expansion joints with the sealant torn out
  • Mouldy silicone around WCs, urinals and vanity tops

For a shop at a centre such as The Mall Maidstone, 2.4 miles south of Boxley, tidy joints at counters and displays matter as much as the fixtures.

What to look for in a quote

  • What site paperwork they can supply
  • Is the sealant right for the movement and the substrate?
  • Do they follow the manufacturer’s priming guidance?
  • What the guarantee covers, and for how long

Questions to ask before you appoint anyone

Shops, offices and hotels in and around Boxley

A 2-mile radius around Boxley takes in 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. Boxley has at least three named business or industrial parks inside a 3-mile radius. Units on sites like these change tenants and get refitted, and each refit leaves joints to seal, often in a colour the occupier specifies.

Sites a few miles apart, such as Viewpoint Industrial Estate and Lordswood Industrial Estate, can share one programme and one point of contact. If you run a unit on an estate such as Viewpoint Industrial Estate, which lies south of Boxley, the trade counter, offices and staff facilities have joints to look after as well as the warehouse.
