About our commercial sealant contractors in Boarhunt

If you look after more than one building, a single sealant contractor saves a lot of chasing. We take on one-off reseals, runs of jobs across a portfolio and planned maintenance programmes, run the same way on every site: send details, get a fixed quote, we seal, and a 12-month guarantee once it’s signed off. To get a programme moving in Boarhunt, ring 01277 525 020 or send details through our quote form with the site addresses. If you’re dealing with movement joints packed with grit and debris and greasy, split joints in a kitchen or tea point, we can put it right, on movement joints in walls and floors, kitchen worktops and splashbacks and floor and threshold joints alike. A specialist sealant contractor works differently from a general builder: on jobs in Boarhunt, preparation and product choice get the time they need.

A lot of what we do in Boarhunt is replacing sealant that has done its years: split, chalky or peeling, with leaks or mould starting behind it.

Work in smaller places such as Boarhunt tends to come one building at a time: a pub kitchen, a hall, a small office. We’ll want a full list and photographs first, so the right products come on the day and nothing waits for a second trip.

What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Questions we’re asked in Boarhunt

Our building in Boarhunt is near the coast: does that change the sealant?

It can. Driven rain and salt are tougher on outside sealant than sheltered inland conditions. That puts more weight on product choice, primers where the manufacturer specifies them, and correct joint sizing.

Must a hotel around Boarhunt close while you work?

Almost never. The work is phased so most rooms stay available. Housekeeping and our team agree each day’s rooms.

How long before the joints can be used?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

Are you CHAS accredited and on Constructionline?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member.

How long will the new sealant 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 checks let you plan resealing before leaks or damage.

Is Boarhunt in your area?

Yes. Boarhunt falls within our area, and the simplest way to start is to ring 01277 525 020 or send details through our quote form.

Do you work for facilities managers and managing agents?

Yes. We quote, schedule and report back in the way that suits your process, with a 12-month guarantee on the workmanship.

From enquiry to sign-off

Before we leave any area, the masking comes off, the area is cleaned and every joint is checked. If an area should be left alone while the sealant cures, we say how long and put signs out. For work around Boarhunt, we aim to finish in one visit, so photos and measurements up front really help. Then the right materials arrive with us.

  1. You send photographs, drawings or a list of the joints and areas involved, and a site visit is booked where it helps.
  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. We strip the failed bead and prepare both faces of the joint.
  5. We fit backing to the right depth, prime where specified and lay the new bead.
  6. Each area is inspected, signed off and backed by our 12-month guarantee.

Before we start on site

  • Tell staff and tenants when we’ll be in
  • Confirm the product named in the specification
  • Point out parking and an unloading spot

Why act early in Boarhunt

Putting off a reseal typically moves the cost rather than avoiding it. Water past a frame perimeter or a washroom joint can reach plasterboard, insulation, floor coverings and the ceiling below, and the bill then involves other trades. Dealing with it while the damage stops at the bead is the cheaper route. For buildings around smaller places like Boarhunt, 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.

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

How the job changes by surface

Shop fronts and retail fit-outs

In retail, sealant is on show. Counters, display units, shopfront frames and floor trims all need a neat line. We’ll confirm the colours available for the specified product.

Facade and cladding joints

Facade joints move every day as panels warm and cool. They need a sealant with the right movement capability, laid at the right depth. Access, such as scaffold already up, is agreed before the price is fixed.

How the quote is worked out

There’s no standard rate for sealant work, since sites vary so much. What we take into account:

  • Site requirements such as inductions and permits
  • Quantities, in metres or numbers
  • Location, for remote and island sites
  • Joint width, depth and condition

Cost follows what’s involved: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.

What we need to price the job

However big the job, these details speed things up:

  • Access details, including height
  • Any dates the work must fit around
  • Drawings or a marked-up plan, if available
  • Clear photos of the problem areas

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 photos and a few notes.

Should maintenance staff do it?

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Sealant on show in Boarhunt’s commercial buildings
