Should maintenance staff do it?

Redoing a failed joint typically costs more than getting it right at the outset, since all of it has to come out and the faces be cleaned back again. That’s why many clients bring in a specialist from the beginning.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong normally costs more in the end than doing them right.

Commercial sealant contractors for commercial buildings in Eyhorne Street

Sealant joints are easy to overlook until one lets water in, and on a working site that typically surfaces as a leak, a stain or a complaint from occupiers. Mastic Doctor works as a commercial sealant contractor for facilities managers, managing agents and main contractors with sites in Eyhorne Street. We find out why the sealant joints failed, take them out and seal again using a sealant that suits the joint. If you’re dealing with earlier reseals applied straight onto the failed bead and external beads that have gone brittle and cracked, we can put it right, on floor and threshold joints, kitchen worktops and splashbacks and window and door perimeters alike. Facilities teams, main contractors and managing agents in Eyhorne Street tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

A lot of what we do in Eyhorne Street is replacing sealant that has done its years: hardened, cracked or shrunk away from the faces, and letting water or dirt in.

A job in a smaller place like Eyhorne Street is typically a single building. We will want a full list and photographs first, so the right products come on the day and nothing waits for a second trip.

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

Common questions from Eyhorne Street clients

Is Roebuck Business Park, near Eyhorne Street, within your area?

Yes. Estates, retail parks and business parks around Eyhorne Street, Roebuck Business Park among them, are all within reach. Photos and a short description are enough for a first look.

Is Eyhorne Street too small for you to travel to?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Can you follow the specification on our project?

Yes. The specification and the manufacturer’s installation guidance are what we work to, and any queries are raised before we start.

Can weather delay the job?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.

Is your work guaranteed?

It’s backed by our 12-month guarantee. Should anything we did fail within that period, let us know.

Can you handle sealant work across several sites?

Yes, across South East England, Greater London and all of Scotland. One contact and one process for every building makes a portfolio easier to manage.

Can you take on work for an FM or managing agent?

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

Aftercare for building managers

For the best life from the joints:

  • Don’t let cleaning or traffic back on before the cure time is up
  • Keep abrasive pads and scrapers off resealed joints
  • Put external and wet-area joints on a regular inspection round
  • Note dates and locations of sealant work for future planning

Give fresh sealant time to cure before it’s cleaned, wetted or walked past. Cure time varies with the product, conditions and depth of the joint, so we confirm it for each area at handover. Leaving the area closed until then keeps the bead neat.

Each spell of wet weather pushes more water through an open joint. It can run into cavities, insulation and internal finishes long before anyone sees a stain. Catching it at the sealant stage avoids the bigger repair.

What sealant work can’t fix

A proper diagnosis includes knowing what sealant can’t do. We will tell you if the real problem is any of the following:

  • Leaks from pipework, wastes or valves (that’s plumbing)
  • Misted, cracked or failed glazing units (a glazier’s job)
  • A failed roof covering or waterproofing membrane

If you’re not sure, just ring 01277 525 020 or email us and we’ll give you a straight answer before you book.

Surfaces we seal

  • Floor and threshold joints
  • Washrooms and tea points

Common problems we fix in Eyhorne Street

External sealant takes a steady beating from the weather. Sunny elevations dry the surface out and exposed ones take driving rain; in time the surface chalks, hardens and cracks. Once it stiffens, the joint opens up at the next big temperature swing.

These are often picked up first by site or facilities staff:

  • Layers of sealant, all of them failing
  • Damp patches where an external joint has failed
  • Smeared sealant across finishes from a rushed job
  • Hardened, chalky sealant on south-facing or exposed elevations

Offices at parks like Roebuck Business Park (to the south-east of Eyhorne Street) have receptions, kitchens and glazed partitions where a tidy joint matters.

What your quote should include

  • Their plan for phasing and protecting the area
  • Whether old or failed sealant will be cut out, not overlaid
  • Do they follow the manufacturer’s priming guidance?
  • Health and safety accreditation such as CHAS
