Sealant specialists in Bulstrode

Inside a commercial building, sealant does a lot of quiet work: around sanitaryware, along worktops and splashbacks, at window boards, partition heads and floor junctions. Externally it keeps rain out of frame perimeters, panel joints and movement joints. Our applicators work on both the inside and the outside of the building, picking the product for each location rather than one tube for everything. If you’re dealing with layers of sealant, all of them failing and water staining near frames, panels or ceilings, we can help, on washrooms and tea points, kitchen worktops and splashbacks and floor and threshold joints alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Bulstrode it comes down to the same thing: the right product in a properly prepared joint.

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

Business units in the countryside around places like Bulstrode are often converted barns, stables or farmyards. Their mix of old walls with new frames, partitions and floors means many joints between unlike materials.

A 12-month guarantee applies to all our work. Should something we installed fail, call 01277 525 020 or use the quote form and we will come back to it.

What we are called out for in Bulstrode

Plenty of failed joints were never sealed with the right product. Painters’ acrylic in a moving joint, vinegar-smelling silicone on metal or natural stone, or a high-modulus product where a low-modulus one was needed. Guidance such as BS 6213 exists to steer sealant selection for exactly this reason, and many specifications refer to it.

Common reasons buildings call us in:

  • Messy, uneven beads from earlier work that let the building down
  • Expansion joints with the sealant torn out
  • Earlier reseals applied straight onto the failed bead
  • Weathered facade sealant that no longer flexes

Parks like Chancerygate Business Centre, 2.2 miles to the north-east of Bulstrode, see tenants come and go, and every move-in brings joints to seal.

What to look for in a quote

  • Health and safety accreditation such as CHAS
  • Their public liability cover
  • What the guarantee covers, and for how long
  • The named product and why it was chosen

Choosing a commercial sealant contractor

What the job involves on each surface

Movement joints in walls and floors

A trafficked floor joint needs a different product from a wall joint. We’ll recommend the right filler or sealant for the traffic and movement, and tell you if the edges need repairing first.

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 we can’t put right

Before quoting, we check that sealant is the right answer. It won’t put right:

  • Leaking roofs, gutters or flat-roof membranes (those need a roofer)
  • Misted, cracked or failed glazing units (a glazier’s job)
  • Walls or slabs moving more than any sealant can take

Not sure which it is? You can ring 01277 525 020 or send photos by email and we’ll tell you honestly.

Joints and surfaces we work on

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

Leave it or put it right?

Fixing joints complaint by complaint is a costly way to manage sealant. A planned programme groups work by building or area, cuts repeat visits and gives you a budget figure. We can help you prioritise, starting with the joints most likely to let water in. Around Bulstrode, it’s better to renew all the failing joints at once, rather than one at a time. Send photographs of each area and we’ll quote for the lot.

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we’ll put a fixed figure on it.

Why choose Mastic Doctor in Bulstrode

  • Failed material removed, not covered up
  • Work to your specification and the manufacturer’s guidance
  • Constructionline member
  • Workmanship guaranteed for 12 months

Keeping the joints sound

To get the most from the new sealant:

  • Keep abrasive pads and scrapers off resealed joints
  • Check joints after other trades have worked nearby
  • Have extract fans checked so wet areas dry out
  • Add sealant to the planned maintenance inspection list

Add the resealed joints to your planned maintenance inspections. Regular checks pick up small failures before they become leaks. If anything looks wrong, call 01277 525 020 or email a schedule or drawings with a photo.

Sealant rarely fails all at once across a building. The first failures are often a warning about the rest. We’ll tell you which sealant joints need doing first and which can wait.

From enquiry to sign-off

In a busy building, we agree a sequence with your contact so the disruption stays in one area at once. Each section is protected, cleaned back and sealed, then reopened once the sealant allows before we move to the next. If others near Bulstrode need work, visits can be combined, which keeps travel down. You’ll have a fixed quote before work starts.

  1. You send photos, drawings or a list of the joints and areas involved, or we arrange a site visit.
  2. Next comes a diagnosis and a fixed quote.
  3. We plan around your site hours and access windows, phasing the work where areas have to stay in use.
  4. Failed sealant is cut out and each joint cleaned back to sound, dry faces.
  5. Backing and primer go in where needed, then the chosen sealant is applied and tooled.
  6. Each area is inspected, signed off and backed by our 12-month guarantee.

Getting the site ready

  • Agree which areas must stay open
  • Tell us what induction or permit system the site runs
  • Have the specification and drawings to hand

Getting a fixed quote

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.

Questions about Bulstrode

Will our hotel in Bulstrode need to close for the work?

Rarely, if ever. We take a few rooms out at a time. Housekeeping and our team agree each day’s rooms.

Do you cover business parks and estates near Bulstrode, such as Chancerygate Business Centre?

Yes. Our area takes in Bulstrode and its surroundings, with estates and business parks such as Chancerygate Business Centre included. A few photos and the unit address let us price the work.

Is Bulstrode in your area?

Yes. Bulstrode falls within our area, and you can give us a call on 01277 525 020 or email us to get started.

Do you check for asbestos before removing sealant?

It can, on some older buildings. So we check the register first and stop work on anything suspect until it’s tested.

Do you seal on top of existing sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

Are you CHAS accredited?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.

Can you follow the specification on our project?

Yes. We follow the specification, along with the manufacturer’s installation guidance.
