Commercial sealant contractors for commercial buildings in Lynsted

Having a single contact for all your sites makes sealant far simpler to manage. We take on one-off reseals, runs of jobs across a portfolio and planned maintenance programmes: send details, get a fixed quote, we seal, and a 12-month guarantee once it’s signed off. For sites in Lynsted, the quickest start is to ring 01277 525 020 or email us with a list of addresses. If you have wall and floor joints that have lost their seal and a top-up bead over failed sealant, now lifting, we can help. Facilities teams, main contractors and managing agents in Lynsted tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

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

A job in a smaller place like Lynsted is normally a single building. We’ll want a full list and photographs first, so the right products come on the day and nothing waits for a second trip.

The 12-month guarantee is for workmanship rather than wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

What sealant work can’t fix

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Structural cracks or movement the joints weren’t designed for
  • Removing asbestos-containing materials (a licensed or specialist contractor’s job)
  • Leaking roofs, gutters or flat-roof membranes (those need a roofer)

If you are not sure, just give us a call on 01277 525 020 or send details through our quote form and we’ll give you a straight answer.

Where we work in Lynsted

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

For managing agents and facilities managers

We work for building owners and managing agents on sealant work across single buildings or whole portfolios around Lynsted. One quote can cover more than one site, which keeps the paperwork simple.

Agents, factors and owners’ representatives all follow the same route: send details, get a fixed quote, we seal, guaranteed. We can agree access arrangements and keyholder contacts beforehand.

Lynsted: questions and answers

Is Kent Science Park, near Lynsted, within your area?

Yes. Estates, retail parks and business parks around Lynsted, Kent Science Park among them, are all within reach. Photos and a short description are enough for a first look.

Is Lynsted off your patch?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

Are you CHAS accredited and on Constructionline?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

How long will the new sealant last?

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.

How do you choose the sealant?

A specification, where there is one, decides it. If there isn’t one, it comes down to the joint: its movement, its surfaces and what it has to cope with.

Can you take on work for an FM or managing agent?

Yes. You can send details through our quote form, and we will confirm any paperwork you need with the quote.

What site paperwork can you provide?

We confirm documents at quote stage: RAMS, an insurance certificate and CSCS details are the usual requests. Our applicators are CSCS-carded.

When to bring in a specialist

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

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. For that reason, many FMs and contractors use a sealant specialist from the outset.

How a job runs

We bring the products specified for the job, along with primers and backing rod. Joint faces are cleaned back to sound, dry surfaces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. Smaller jobs around Lynsted can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  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. Where parts of the building must stay open, the work is phased.
  4. Old sealant is cut out completely, never sealed over.
  5. Each joint gets a suitable sealant, laid to depth and tooled.
  6. A final walk-round, then the 12-month guarantee applies.

Before we start on site

  • Send asbestos survey details if the building is pre-2000
  • Clear stock, furniture or equipment away from the joints
  • Tell staff and tenants when we will be in

Request a quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.

Advice

What sets the cost

There’s no standard rate for sealant work, because every site is different. What we take into account:

  • Specialist products, such as fire-rated or hygienic sealants
  • Whether old sealant has to be cut out first
  • The site’s rules and procedures
  • Distance, for remote addresses

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote and we will explain how it’s made up.

What to include in your enquiry

Diagnosis starts before we arrive. Let us know:

  • Asbestos survey details if the building is older
  • Photos of the joints, close up and from further back
  • Your programme or deadline
  • Access details, including height

The quickest route to a quote is a few photos and the site postcode. Send them through the quote form, or call the office on 01277 525 020 or use the quote form to discuss it first.

After the work

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Put external and wet-area joints on a regular inspection round
  • Keep abrasive pads and scrapers off resealed joints
  • Have extract fans checked so wet areas dry out
  • Check the asbestos register before anyone disturbs old sealant in an older building

Later works are the usual way new joints get damaged. When fittings are moved or cabling added, the sealant nearby is easily disturbed, and it’s easy to forget to reseal afterwards. If that happens, call the office on 01277 525 020 or send details through our quote form and we will price putting it right.

Sealant installed at the same time typically fails in sequence. The first failures are often a warning about the rest, so it makes sense to look at the wider elevation or block. We’ll tell you which sealant joints need doing first and which can wait.
