Commercial sealant contractors in Lexden

We have applied sealant on commercial sites for over 20 years, and the documents buyers ask for are ready: we are CHAS accredited and a Constructionline member, our applicators hold CSCS cards, and we carry five million pounds of public liability insurance. If your site needs RAMS, an insurance certificate or CSCS details, say so and we’ll confirm with the quote. We work on movement joints in walls and floors, window and door perimeters and external facade joints, and the usual reasons a site gets in touch are window and door perimeter joints that have cracked open and weathered facade sealant that no longer flexes. A single leaking joint is often how a building in Lexden first comes to us: we look at the rest while we are there and tell you what we find.

On a typical commercial building in Lexden, the joints that fail first are the hardest-worked ones: south-facing perimeters, entrance thresholds and busy washrooms.

Sealant jobs for businesses in a place the size of Lexden are often best grouped: shopfront, washroom, kitchen and any external joints done together. That keeps travel and disruption down.

We sign every job off with a 12-month guarantee. It’s a plain promise: if the work we did fails within twelve months, we return to fix it.

What Lexden’s businesses ask us to seal

Lexden is in the South East, one of the UK’s drier regions. External joints still need dry faces and the right temperature, and damp or frosty mornings can hold work up. At about 49 miles from central London, Lexden 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.

A hotel such as The Grosvenor Hotel (1.1 miles east of Lexden) shows how much sealant a hospitality building has on show, from bathroom joints to the bar. Premises within reach of Colchester station (1.6 miles north-east of Lexden) often have busy frontages where joints are seen by everyone passing. Sites a few miles apart, such as Stanway Retail Park and Angora Business Park, can share one programme and one point of contact.

Lexden is about 1 mile west of Colchester, in Essex. Any commercial site in Lexden is covered, for single jobs and planned programmes alike. Across Essex, 644 places are covered, Lexden among them. London is covered too, some 49 miles away.

We cover the CO3 and CO2 postcode districts. We cover commercial and managed buildings on Park Road, Heath Road and Capel Road. You’ll find Lexden on or near the A1124, so getting applicators and materials to site is simple.

Why deal with it now?

Fixing joints complaint by complaint is a costly way to manage sealant. Planning the work across a year or a portfolio means fewer separate visits and a predictable spend. We can help you prioritise, starting with the joints most likely to let water in. In a smaller place such as Lexden, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.

The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.

How a job runs

At the end of each section, the masking comes off, the area is cleaned and every joint is checked with your site contact.

  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.

Surface by surface

Commercial kitchens and tea points

Kitchen joints along worktops, sinks, splashbacks and wall cladding collect grease and moisture. Proper degreasing comes before any new sealant, and a hygienic or food-safe sealant is used where food contact is possible.

Movement joints in walls and floors

Brickwork, blockwork and floor slabs all have movement joints that need a flexible seal. When the seal fails, debris gets in and the joint stops working. The joints are resealed using a sealant matched to the movement and any traffic.

After the work

After handover, a little attention goes a long way:

  • Make sure ventilation in wet areas is switched on and working
  • Make sure contractors see the asbestos survey before cutting out old mastic
  • Keep abrasive pads and scrapers off resealed joints
  • Note dates and locations of sealant work for future planning

In washrooms and kitchens, extraction makes a real difference to sealant life. Fans that are broken or switched off leave joints damp for longer, which is how mould gets back in. It’s worth having fans checked while the sealant is fresh.

A failed external joint lets water in every time it rains. It can run into cavities, insulation and internal finishes long before anyone sees a stain. Resealing early keeps the problem in the sealant and out of the building.

Cost factors for sealant joints

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

  • Induction, permit and paperwork requirements
  • Quantities, in metres or numbers
  • Working within restricted access windows
  • Travel to remote or island sites

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

What we need to price the job

We can often quote from photos and a few details. It helps to include:

  • Any dates the work must fit around
  • The product your specification calls for
  • Approximate linear metres or a joint schedule
  • The asbestos register, for older buildings

For a fixed quote, call the office on 01277 525 020 or use the quote form with the site address and an outline of the work. Our quote form is another easy route.

Should maintenance staff do it?

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

Certain joints really need a specialist: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

FAQs: Lexden

Is Stanway Retail Park, near Lexden, within your area?

Yes, sites like Stanway Retail Park are within our area, along with the rest of Lexden. Photos and a short description are enough for a first look.

Is Lexden off your patch?

No. Small places get the same service as large ones. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Will the building have to shut during the work?

We phase the work so parts of the building stay open. We plan around the site hours and access windows you give us.

Do you seal on top of existing sealant?

No, never. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

Do you work directly for building managers?

Yes. You can send details through our quote form, and tell us what site paperwork you need.

How long will the new sealant last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Sealant joints are maintenance items, so inspect them regularly.

Do you work to architects’ specifications?

Yes. Send it with your enquiry, and we will price the work to it.
