Commercial sealant contractors for commercial buildings in Lambourn Woodlands

Mastic Doctor has been sealing joints for businesses and contractors since 2005, 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. Site teams most often ask us about earlier reseals applied straight onto the failed bead and damp patches where an external joint has failed, across window and door perimeters, kitchen worktops and splashbacks and floor and threshold joints. Facilities teams, main contractors and managing agents in Lambourn Woodlands tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

The most common commercial job in Lambourn Woodlands is resealing joints that have simply reached the end of their life: split, chalky or peeling, with leaks or mould starting behind it.

In and around smaller places such as Lambourn Woodlands, the commercial buildings we’re asked about are often pubs, shops, village halls and barns converted to offices. Kitchens, toilets and window frames in all of them need resealing sooner or later.

A 12-month guarantee applies to all our work in West Berkshire. Should something we installed fail, call the office on 01277 525 020 or send photos by email and we’ll come back to it.

How a job runs

Site rules come first: signing in, inductions and any permit to work. Once we’re cleared to begin, we take the joints in the sequence agreed with you. For a building around Lambourn Woodlands, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  1. Site photographs, drawings or a visit tell us what’s there and how it has failed.
  2. A fixed quote follows, with removal and preparation included.
  3. Sequence, access and working times are settled before the first joint is touched.
  4. The failed sealant comes out and the faces are prepared, with primer where required.
  5. Backing goes in, the new sealant is laid and tooled, and the area is left neat.
  6. We hand back each area with its cure time and our 12-month guarantee.

What we need from you

  • Send any specification or drawings in advance
  • Agree which areas must stay open

What sets the cost

We price every job individually. The things that drive the figure:

  • Whether old sealant has to be cut out first
  • Phasing around occupants
  • Travel to remote or island sites
  • How accessible the joints are

We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

Sending details for a quote

Whether it’s one area or a whole building, these details speed things up:

  • Approximate linear metres or a joint schedule
  • The postcode of the building
  • Any dates the work must fit around
  • What the building is and how it’s used

Tell us about the building, the joints and when you need the work done, and a fixed quote will follow. To get it moving, call 01277 525 020 or use the quote form.

Why deal with it now?

A cheaper quote sometimes means the old bead stays in. New sealant laid on old silicone has nothing to bond to, so it peels. Our prices always include removal of the failed bead and full joint preparation, because that’s what makes the new bead last. For buildings around smaller places like Lambourn Woodlands, water damage can go unnoticed for longer, especially where a building isn’t used daily, which gives a failed joint time to do damage. Renewing joints in good time avoids the problem.

Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Why appoint us

  • CSCS-carded applicators
  • A fixed quote before work starts
  • CHAS accredited
  • One number for every site we cover

Common questions from Lambourn Woodlands clients

Can you match sealant colours for premises in Lambourn Woodlands?

Yes, we can typically get close to most finishes from the product’s colour range. Send colour references or photographs and we’ll confirm what’s available for the product.

Is a smaller place like Lambourn Woodlands outside your area?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Are you CHAS accredited and on Constructionline?

Yes. We’re CHAS accredited and a Constructionline member.

How long do sealant joints last?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

How soon can the area be used again?

We will confirm how long the chosen product needs to cure.

What site paperwork can you provide?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We are CHAS accredited and a Constructionline member, with five million pounds of public liability insurance.

What about asbestos in old mastic?

Some older mastics did contain asbestos. So we check the register first and stop work on anything suspect until it’s tested.

What the job involves on each surface

Shop fronts and retail fit-outs

Most shops can’t close for a reseal. Tell us your trading hours and access windows and we’ll plan around them, phasing areas so the shop floor stays usable.

Washrooms and toilets

Around WCs, urinals, vanity tops, IPS panels and cubicles, sealant is wet most of the day. Old sealant comes out and a sanitary silicone with anti-mould additives goes in, with phased work so some facilities stay open.

What we can’t put right

Not every problem is a sealant problem, and we’re upfront when that’s the case. It won’t fix:

  • Removing asbestos-containing materials (a licensed or specialist contractor’s job)
  • Roof leaks that only look like a joint problem
  • Broken glass or blown double-glazed units

If you’re not sure, just call the office on 01277 525 020 or email the details over and we’ll give you a straight answer.

Joints and surfaces we work on

  • Kitchen worktops and splashbacks
  • Movement joints in walls and floors
  • Floor and threshold joints
  • Washrooms and tea points
  • External facade joints
  • Window and door perimeters

For managing agents and facilities managers

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Sites in Lambourn Woodlands can sit alongside others in a wider programme.

Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first.
