Commercial mastic work in Chambers' Green

We have applied sealant on commercial sites for over 20 years, and the paperwork side is in order: CHAS accredited, Constructionline member, five million pounds of public liability insurance and CSCS-carded applicators. Let us know which site documents you need and they’ll be confirmed with the quote. If you have untidy joints in a reception, shop floor or lobby and mouldy silicone around WCs, urinals and vanity tops, we can put it right, on kitchen worktops and splashbacks, washrooms and tea points and floor and threshold joints alike. Searching for sealant specialists in Chambers' Green? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.

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

A job in a smaller place like Chambers' Green is normally a single building. We plan the visit so everything on the list is done in one go, with the right products and colours on hand.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

Cost factors for sealant joints

We price every job individually. The main factors are:

  • Removal of failed or old sealant
  • Backing rod, priming and other preparation
  • Travel to remote or island sites
  • How much there is to seal

Access often affects the price as much as the sealing: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

What to include in your enquiry

For an accurate fixed quote, we need a clear picture of the site. Send us:

  • When you need the work done
  • Drawings or a marked-up plan, if available
  • Clear photos of the problem areas
  • Specification clauses that apply

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, call the office on 01277 525 020 or send details through our quote form.

Looking after the joints

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

  • Log reseals in the O&M or maintenance records
  • Respect the cure time before reopening an area
  • Ask fit-out and M&E contractors to report any sealant they disturb
  • Put external and wet-area joints on a regular inspection round

Put sealant on the planned maintenance checklist. A periodic look catches splits and lifting edges early, with external elevations and wet areas first in line. Should something look amiss, you can call the office on 01277 525 020 or email a schedule or drawings and send a picture.

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.

Different surfaces, different methods

Movement joints in walls and floors

Movement joints in walls and floors let the structure expand and contract. 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.

Facade and cladding joints

Facade joints move every day as panels warm and cool. They need a sealant with the right movement capability, laid at the right depth. We confirm the access in place before we quote.

When to bring in a specialist

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.

When to call us in Chambers' Green

When a bead peels cleanly off one face, it has failed in adhesion. The usual causes are poor preparation, a missed primer, contamination on the joint face or sealant bonded to the base of the joint. We see it often where joints were sealed in a hurry.

Any of the following is a good reason to get the joints checked over:

  • Greasy, split joints in a kitchen or tea point
  • Untidy joints in a reception, shop floor or lobby
  • Sanitary sealant that has gone black and patchy
  • Leaks that seem to come through a sealant line

Offices and shops close to stations such as Pluckley station (less than half a mile south of Chambers' Green) tend to be busy all day, so sealant work is planned around opening hours.

Choosing a commercial sealant contractor

Questions we are asked in Chambers' Green

Is Chambers' Green off your patch?

No. Places such as Chambers' Green are covered as much as the big towns. We work across Greater London and the South East. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Which documents can you supply for work in Chambers' Green?

We will confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. We hold £5m public liability insurance, are CHAS accredited and a Constructionline member, and our applicators are CSCS-carded.

Do you work directly for building managers?

Yes. We quote, schedule and report back in the way that suits your process.

How do we get a quote?

The main factors are metres of joint, removal, access, the product and how many phases there are. To get a fixed price, send details through our quote form, or phone or email us.

Does weather matter for sealant work?

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

How long will the new sealant last?

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

Do you hold CHAS accreditation?

Yes. We’re CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.

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. Rural sites near Chambers' Green may need directions, gate codes or a contact on site. Send that with the details and we will confirm the plan with the quote.

  1. First, details come to us: photographs, drawings or a schedule of the areas.
  2. The failure is diagnosed and a fixed quote issued for the work agreed.
  3. Site hours, access windows and the order of areas are agreed before we start.
  4. The failed bead is removed and the joint faces cleaned until they’re sound and dry.
  5. Backing and primer go in where needed, then the chosen sealant is applied and tooled.
  6. Finished joints are checked with you and handed over with our 12-month guarantee.

Preparing the site

  • Arrange parking or a loading space
  • Agree which areas must stay open
  • Warn occupants and staff about the work
