Commercial sealant contractors in The Chart

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

Your questions answered

Can the sealant on our The Chart premises match the finishes?

Yes, sealants come in a wide range of standard colours, and matching to RAL references, cladding, stone or frames is a common request. The quote lists the colours the product is made in.

Is The Chart too small for you to travel to?

No. Small places get the same service as large ones. We work across Greater London and the South East. Good photographs up front let us bring everything on the first visit.

When is resealing likely to be due?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

Is it fine to apply new sealant on top of old?

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

Do your applicators hold CSCS cards?

Yes. Should the site need card details in advance, let us know and we will send them with the quote.

Do you hold CHAS accreditation?

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

How is commercial sealant work priced?

Photos, drawings or a schedule of the joints are usually enough to start through our quote form. If a visit is needed we’ll book one, and a fixed quote follows.

Commercial sealant contractors in The Chart

Pricing a commercial reseal is a short process. Our quote form takes photographs, drawings or a schedule of the areas. Where the photographs don’t tell the full story, we arrange a site visit, followed by a fixed quote rather than an estimate that drifts. If you have untidy joints in a reception, shop floor or lobby and frame mastic that has hardened and come away from the wall, we can help, on external facade joints, window and door perimeters and floor and threshold joints alike. For commercial sealant work in The Chart, you deal with one contact from quote to sign-off, whether it’s one building or several.

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

Business units in the countryside around places like The Chart are often converted barns, stables or farmyards. Old masonry beside new aluminium, timber and plasterboard gives plenty of joints between materials that move differently, and a sealant colour that suits the building’s character is often part of the brief.

Every job is signed off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Our process

Working in a building that stays open takes some planning. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. For work around The Chart, we aim to finish in one visit, so photographs and measurements up front really help. That way the right products come on the day.

  1. Site photographs, drawings or a visit tell us what’s there and how it has failed.
  2. You get a fixed quote covering removal, preparation and the new sealant.
  3. We agree the order of work, access windows and site hours with you.
  4. Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
  5. Depth is set with backing, then the sealant is applied, tooled and the area tidied.
  6. Completed areas are signed off with you under our 12-month guarantee.

Before we start on site

  • Have the specification and drawings to hand
  • Clear stock, furniture or equipment away from the joints
  • Point out any areas we must not close

Ask for a quote

A good quote starts with a clear picture: the joints involved, quantities, access and the product called for. Share whatever details you have and we will fill any gaps with a visit.

Common problems we fix in The Chart

Washrooms and kitchens wear sealant out in their own way. Damp, harsh cleaning products and poor ventilation let mould take hold inside the bead, and once established it rarely cleans out. Replacement with a sanitary anti-mould silicone is the lasting answer.

Most enquiries start with one or more of the following:

  • Frame mastic that has hardened and come away from the wall
  • Messy, uneven beads from earlier work that let the building down
  • Gaps behind commercial kitchen worktops and sinks
  • A top-up bead over failed sealant, now lifting

Whatever the building in The Chart, commercial sealant work starts with cutting out the failed bead and cleaning the joint back to sound material.

How to choose a sealant contractor

What sets the cost

There’s no standard rate for sealant work, because every site is different. What we look at:

  • Access and working height
  • Working within restricted access windows
  • Location, for remote and island sites
  • The site’s rules and procedures

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Details that help us quote

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

  • The asbestos register, for older buildings
  • The site address and postcode
  • When you need the work done
  • Photos of the joints, close up and from further back

A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or speak to us on 01277 525 020 or email a schedule or drawings if you’d rather talk the job through.

Frontages, fit-outs and joints in The Chart

The Chart lies roughly 18 miles out from central London. 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 2-mile radius around The Chart takes in a number of hotels. Hotel refurbishments are where a matched sealant colour earns its place: bathroom, bar and reception joints have to sit with the finishes.

Offices and shops close to stations such as Hurst Green station, 1.6 miles west of The Chart, tend to be busy all day, so sealant work is planned around opening hours.

The Chart is about 6 miles south-east of Caterham, in Surrey. We send applicators to The Chart for sealant joints, handled exactly as we handle every other area. We work across 379 places in Surrey, from busy centres to rural villages. There’s a separate page for London, roughly 18 miles from The Chart.

Why it’s worth doing now in The Chart

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. A careful reseal is a far smaller undertaking than replacement, though we’ll tell you honestly if the element itself is the problem. Halls, stores and units around places like The Chart may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

The specified product makes a difference, as does the preparation each joint needs. Access, phasing and site rules also count.

Why us?

  • Work to your specification and the manufacturer’s guidance
  • Failed material removed, not covered up
  • Over 20 years of commercial sealing
  • Standard and matched colours in many product ranges

Looking after the joints

For the best life from the joints:

  • Check joints after other trades have worked nearby
  • Log reseals in the O&M or maintenance records
  • Act on the first lifting edges rather than waiting
  • Add sealant to the planned maintenance inspection list

Keep an eye out for other trades after we have gone. Shop refits, new services and replaced fittings often break the seal around them. Where work has disturbed a joint, just call the office on 01277 525 020 or send photos by email for a quote.

Once sealant fails in a movement joint, grit and debris get in. The joint can no longer close, so its edges crack or spall. That turns a sealant job into something bigger.

Site staff or a sealant specialist?

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.
