Commercial sealant contractors for commercial buildings in Stocks Green

Most of the buildings we seal stay open while we are there. Work is scheduled around the site hours and access windows you give us; phasing keeps some washrooms, kitchens or entrances available while others are done. It’s the same approach in offices, retail units, hotels, schools and healthcare buildings. Site teams most often ask us about external beads that have gone brittle and cracked and layers of sealant, all of them failing, on floor and threshold joints, window and door perimeters and movement joints in walls and floors. Looking for mastic applicators who cover Stocks Green? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.

Multi-site clients with buildings in and around Stocks Green can put several sites on one programme, with one quote format and one point of contact.

Rural business units near smaller places such as Stocks Green are frequently converted agricultural buildings. Their mix of old walls with new frames, partitions and floors means many joints between unlike materials.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Why it’s worth doing now in Stocks Green

A failed seal around a window, worktop or panel doesn’t mean the element itself has to go. 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. Halls, stores and units around places like Stocks Green may not be checked every day, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

Pricing sealant joints depends on quantities, condition and access. Call for a quote.

Why us?

  • One number for every site we cover
  • Work to your specification and the manufacturer’s guidance
  • Clear, fixed quotes
  • A Constructionline member, so easy to vet

How a job runs

We bring the products specified for the job, along with primers and backing rod. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and each bead is tooled to a neat concave finish. Jobs in and around smaller places like Stocks Green are usually planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. You send photographs, drawings or a list of the joints and areas involved.
  2. Next comes a diagnosis and a fixed quote.
  3. Before anything is cut out, we agree access, timings and sequence.
  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. We walk the completed areas with you and sign them off under the 12-month guarantee.

What we need from you

  • Point out parking and an unloading spot
  • Point out any areas we must not close
  • Share the asbestos register for older buildings

On a facade, a failed joint is often only visible close up. Close-up photographs or a site visit tell us what’s needed, with colours confirmed for the product chosen.

Quoting for work in Stocks Green

There’s no standard rate for sealant work, since sites vary so much. What we take into account:

  • How accessible the joints are
  • Phasing around occupants
  • Travel to remote or island sites
  • Which sealant the job calls for

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.

What we need to price the job

It doesn’t need to be a full survey. A few details are enough to get going:

  • Specification clauses that apply
  • Anything awkward about access or site hours
  • Any dates the work must fit around
  • Where the site is, with the postcode

For a fixed quote, call the office on 01277 525 020 or email drawings and photos, telling us the site location and the nature of the job. You can also send details through our quote form.

Your questions answered

Can you supply sealant in our brand colour for a site in Stocks Green?

Yes. Colour matching to frames, cladding, stone and shop-fit finishes is a regular part of the work. The quote lists the colours the product is made in.

What site paperwork comes with a job in Stocks Green?

Whatever your site asks for, from RAMS to CSCS details, is confirmed when we quote. We’re CHAS accredited and a Constructionline member, with £5m public liability insurance and CSCS-carded applicators.

Who decides which product is used?

A specification, where there is one, decides it. Without one, the joint decides: how much it moves, what it bonds to and whether it’s wet, trafficked or fire-rated.

Is failed sealant stripped out, or sealed over?

Removal comes first, every time. After that come cleaning, primer where needed, backing and the new sealant.

How long does a job like this take?

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

Is Stocks Green in your area?

Yes. We cover Stocks Green and the rest of Kent, within our coverage of Greater London, South East England and Scotland. To discuss a job, give us a call on 01277 525 020 or email us.

Do you hold CHAS accreditation?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member.

When to bring in a specialist

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.

A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
