Coloured sealant near New Street

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Owners, agents and contractors

Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

About our coloured sealant in New Street

Shop fits, hotels and offices are where colour-matched sealant earns its place. A mismatched bead can make good joinery look unfinished, however well it was installed. We pick a colour from the product’s range that sits with the finish. If you’re dealing with smeared sealant on stone or joinery and colour changes after a rebrand or refit, we can put it right, on cladding panels, shop-fit joinery and counters and powder-coated and anodised frames alike. One point of contact handles commercial sealant work in New Street from the first photographs to the final walk-round, whether it’s one building or several.

In and around smaller places such as New Street, 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.

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

How the quote is worked out

A fixed quote reflects the actual work. It takes account of:

  • The size and state of each joint
  • Any access equipment needed
  • Whether the work must be split into stages
  • Distance, for remote addresses

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.

What we need to price the job

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

  • Photos of the joints, close up and from further back
  • Specification clauses that apply
  • The type of building and who uses it
  • The postcode of the building

Let us know the site, the scope and your timescale, and we’ll put a fixed quote together. To get it moving, phone 01277 525 020 or email a schedule or drawings.

Questions we are asked in New Street

Is a smaller place like New Street outside your area?

Not at all. New Street is within our area. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Can you work at a site such as Bowes Industrial Centre, by New Street?

Yes. Our area takes in New Street and its surroundings, with estates and business parks such as Bowes Industrial Centre included. Send details of the unit and the work through our quote form for a quick quote.

Do you take on small jobs?

Small jobs are welcome alongside larger packages. Photos and a description are enough to start.

Do you hold CHAS accreditation?

Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.

How long does a typical visit take?

We plan the time on site around your programme and access. You’ll have an expected duration with the quote.

How long do sealant joints last?

Nobody can honestly give a figure in years, since movement, weather, cleaning and use all affect it. Regular checks let you plan resealing before leaks or damage.

Can you fit around our working hours?

The office is staffed Monday to Friday, from 8am until 5pm. Tell us your site hours and access windows and the work will be fitted around them.

Commercial premises in New Street

Central London is about 21 miles from New Street. 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. The 3 miles around New Street take in two named trading estates, business parks or retail parks. Tenant changes on such sites bring fit-outs, and fit-outs bring new joints.

Offices and shops close to stations such as Meopham station (to the north of New Street) tend to be busy all day, so sealant work is planned around opening hours. Occupiers with premises at both Bowes Industrial Centre and Heaver Farm Trading Estate could have the sealant at each handled under one quote. Industrial estates such as Bowes Industrial Centre, 0.9 miles north-east of New Street, have offices, trade counters and welfare areas whose sealant ages like any other building’s.

New Street is about 6 miles south of Northfleet, in Kent.

Honest limits

Some faults sit outside our scope, and we point that out rather than sealing over them:

  • Exact bespoke colour matches beyond the product’s range
  • A colour that never alters with age
  • Materials with mixed tones that defy a single match

If you’re not sure, just call the office on 01277 525 020 or email drawings and photos and we will give you a straight answer before you book.

Joints and surfaces we work on

  • Shop-fit joinery and counters
  • Cladding panels
  • Hotel bathrooms and public areas
  • Office fit-out finishes
  • Natural stone and brick
  • Powder-coated and anodised frames

Our process

In a busy building, the work is phased so only one area is out of use at a time. Each area is protected, prepared and sealed, then reopened once the sealant allows before the next one starts. For a building around New Street, tell us how to find it and who will meet us. Add it to your enquiry and we’ll build it into the plan.

  1. First we agree which sealant type the joint needs.
  2. Your RAL reference, sample or photo is checked against that product’s colours.
  3. The nearest colour is agreed, with a sample bead where needed.
  4. The existing bead comes out, then faces are cleaned and backed.
  5. We mask, seal and tool to a clean line.
  6. Masking comes off and the work is checked with you.

What we need from you

  • Tell staff and tenants when we will be in
  • Share your working hours and any access restrictions
  • Make sure the joints can be reached

Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we’ll arrange one.

Related advice

Site staff or a sealant specialist?

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Keeping the joints sound

Once the work is signed off, these steps help:

  • Keep the area clear while the sealant cures
  • Insist on the agreed colour for any repair
  • Agree the sealant colour early and write it into the specification
  • Plan full-run reseals on visible elevations

Expect some change in appearance over the years. Some fading is part of normal ageing outdoors.

Ask for a trial bead on high-profile areas. Seeing the cured colour in place avoids surprises.
