Commercial sealant contractors for businesses in Turnpike Lane

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

Commercial mastic work in Turnpike Lane

Mastic Doctor has been sealing joints for businesses and contractors since 2005, and the documents buyers ask for are ready: 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. We work on external facade joints, floor and threshold joints and window and door perimeters, and the usual reasons a site gets in touch are mouldy silicone around WCs, urinals and vanity tops and smeared sealant across finishes from a rushed job. A specialist sealant contractor works differently from a general builder: in Turnpike Lane, that means joint design, primers and backing rod as standard.

In an occupied building in Turnpike Lane, the job is planned so areas stay in use: washrooms in turn, floors in sections and entrances kept open.

Buildings in a London area such as Turnpike Lane rarely close for maintenance: occupied offices, ground-floor retail under residential floors and busy shared entrances. We plan the joints floor by floor or unit by unit with the building manager, so areas stay in use.

The 12-month guarantee covers our workmanship: preparation, application and finish. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Looking after the joints

Regular inspection catches problems early. In particular:

  • Deal with small splits before they become leaks
  • Keep a record of which joints were resealed and when
  • Have extract fans checked so wet areas dry out
  • Look at the sealant around anything that has been moved or replaced

Let your cleaning contractor know what’s new. Scourers, blades and harsh products shorten a bead’s life; a mild cleaner is all most joints need.

An open joint in a food area or toilet collects dirt and moisture that cleaning can’t reach. Environmental health officers look at how cleanable surfaces are, which makes sound joints worth keeping on top of.

Work for main contractors and building owners

Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first, with CSCS-carded applicators on site.

Building owners and managing agents use us on everything from one building to a spread of sites. One quote can cover more than one site, which keeps the paperwork simple.

How the job changes by surface

Shop fronts and retail fit-outs

Most shops can’t close for a reseal. We plan around the access windows the store gives us, working in sections where that helps.

Commercial kitchens and tea points

In kitchens, sealant lines at worktops, sinks and wall panels take heat, grease and daily cleaning. They’re degreased thoroughly before resealing, with a food-safe or hygienic product wherever food contact can happen.

What happens if it’s left?

It can be tempting to hold sealant work back until the next refurbishment. For internal joints that are only cosmetic, that can make sense, but a joint letting water in now keeps doing damage until the refurb arrives. We can seal the urgent joints now and leave the rest for the programme. Repeat call-outs disrupt occupied London buildings, so a proper job first time, with the old sealant fully removed, is worth it.

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 you get with us

  • Old sealant cut out, never sealed over
  • One number for every site we cover
  • Workmanship guaranteed for 12 months
  • Standard and matched colours in many product ranges

FAQs: Turnpike Lane

Does a hotel in Turnpike Lane need to shut while its sealant is renewed?

Rarely, if ever. We take a few rooms out at a time. We agree the order of rooms and the timings with you before we start.

Do you take on jobs in Turnpike Lane where loading and access are tightly controlled?

Yes, most London buildings have access rules of some kind, and we plan around them. Send the building rules and access times with your enquiry. The ULEZ covers the whole of Greater London, which we allow for

Which sealant will you use?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Do you work for facilities managers and managing agents?

Yes. A large share of our work comes through facilities managers, managing agents and landlords. We can work to your instruction process and site rules.

How long will the new sealant last?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

How long does a typical visit take?

The duration is planned around your programme and the access we’re given. We’ll give you an estimate of time on site when we quote.

How is commercial sealant work priced?

Price depends on joint lengths and widths, how much removal is involved, the product, access and phasing. To get a fixed price, send details through our quote form, or phone or email us.

Units on sites like these change tenants and get refitted, and each refit leaves joints to seal.

Occupiers with premises at both Arena Shopping Park and Crusader Industrial Park could have the sealant at each handled under one quote.

From enquiry to sign-off

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Most London premises stay occupied while we’re on site, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.

  1. First, details come to us: photographs, drawings or a schedule of the areas, or we arrange a site visit.
  2. We work out why the joints have failed and fix a quote for the agreed scope.
  3. We plan around your site hours and access windows, phasing the work where areas have to stay in use.
  4. We strip the failed bead and prepare both faces of the joint.
  5. The depth is set, primer is used where the maker calls for it, and the fresh bead 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
  • Clear stock, furniture or equipment away from the joints
  • Let us know about inductions and permits
