Your questions answered

Will our hotel in Drayton St Leonard need to close for the work?

Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. Housekeeping and our team agree each day’s rooms.

Can the sealant on our Drayton St Leonard premises match the finishes?

Yes, we can usually get close to most finishes from the product’s colour range. The quote lists the colours the product is made in.

Does the weather affect the work?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.

Do you cover Drayton St Leonard?

Yes. Sites across Drayton St Leonard are covered.

What guarantee do you give on resealing?

Each job sits under our 12-month guarantee from handover. Looking after the joints as we advise helps them last.

Will you just go over the old sealant?

No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

Are you CHAS accredited?

Yes. We are CHAS accredited and a Constructionline member.

Commercial sealant contractors in Drayton St Leonard

Mastic Doctor has been sealing joints for businesses and contractors since 2005, and the documents buyers ask for are ready: we are CHAS accredited and a Constructionline member, our applicators hold CSCS cards, and we carry five million pounds of public liability insurance. If your site needs RAMS, an insurance certificate or CSCS details, say so and we will confirm with the quote. If you’re dealing with earlier reseals applied straight onto the failed bead and black mould through washroom sealant that won’t clean off, we can put it right, whatever the surface. Whoever orders the work in Drayton St Leonard, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.

Occupied buildings in Drayton St Leonard need the work phased: we agree the order with you and hand back each area with its cure time.

A job in a smaller place like Drayton St Leonard 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.

The 12-month guarantee covers our workmanship: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

Maintenance after handover

Keep the joints in good shape with a few simple steps:

  • On pre-2000 buildings, share the asbestos information before work starts
  • Keep abrasive pads and scrapers off resealed joints
  • Look at the sealant around anything that has been moved or replaced
  • Report cracked or peeling sealant early

Good ventilation keeps wet-area sealant in better condition. Fans that are broken or switched off leave joints damp for longer. Your maintenance team can look at extract fans at the same time.

Sealant rarely fails all at once across a building. The first failures are often a warning about the rest so the whole run is worth inspecting. We can assess the lot and suggest what to do now and later.

For managing agents and facilities managers

We work for building owners and managing agents on sealant work across single buildings or whole portfolios. Several sites can go on one quote, which keeps the paperwork simple.

Hospitality, education, healthcare, office and retail clients book us directly too. The work is planned around how the building runs, so the building keeps working while we do.

On site: what to expect

Tell us your site hours and access windows and we will plan around them. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. For work around Drayton St Leonard, we aim to finish in one visit, so we ask for photos and rough sizes first. That way the right products come on the day.

  1. We start with the evidence: photographs, drawings or a look on site.
  2. A fixed quote follows, with removal and preparation included.
  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. Backing goes in, the new sealant is laid and tooled, and the area is left neat.
  6. Completed areas are signed off with you under our 12-month guarantee.

Getting the site ready

  • Agree which areas must stay open
  • Let building users know which areas are affected
  • Flag any permit to work we’ll need

What the job involves on each surface

Commercial kitchens and tea points

A smooth, continuous joint is easier to keep clean. We seal to a neat, cleanable finish and work around service times you agree with us.

Fire-rated seals where specified

Fire-rated sealant is only one type of fire-stopping product. Other products, such as collars, wraps and batts, are specified for different services, and we will tell you if the detail calls for something else.

What we are called out for in Drayton St Leonard

If only one face has lost its grip, that’s an adhesion failure. Typical reasons include rushed preparation, no primer where one was needed, dust or release agents on the surface, or three-sided adhesion. We see it often where joints were sealed in a hurry.

What tends to prompt an enquiry:

  • Frame sealant that has cracked, shrunk or pulled away
  • Smeared sealant across finishes from a rushed job
  • Hardened, chalky sealant on south-facing or exposed elevations
  • Water staining near frames, panels or ceilings

For any commercial premises in Drayton St Leonard, a lasting joint depends on full removal of the old sealant and clean, dry faces.

What your quote should include

  • Health and safety accreditation such as CHAS
  • What level of public liability insurance do they hold?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?
  • What the guarantee covers, and for how long

Questions to ask before you appoint anyone

What we can’t put right

Some faults sit outside our scope, and we say so rather than covering them up:

  • Walls or slabs moving more than any sealant can take
  • Water from a services leak rather than a joint
  • Misted, cracked or failed glazing units (a glazier’s job)

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

Joints and surfaces we work on

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