Commercial clients in Bexon

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.

Hospitality, education, healthcare, office and retail clients come to us directly as well. The work is planned around how the building runs, so guests, pupils, patients or staff are disturbed as little as possible.

About our commercial sealant contractors in Bexon

Most commercial buildings carry hundreds of metres of sealant that nobody thinks about until it fails. Mastic Doctor works as a commercial sealant contractor for facilities managers, managing agents and main contractors looking after property in Bexon. Our job is to diagnose the failure, remove the old bead and seal again using a product chosen for the movement and exposure. Site teams most often ask us about earlier reseals applied straight onto the failed bead and window and door perimeter joints that have cracked open, on external facade joints, window and door perimeters and kitchen worktops and splashbacks. A single leaking joint is often how a building in Bexon first comes to us: we look at the rest while we’re there and tell you what we find.

In Bexon, as anywhere, the first joints to go are usually the ones that work hardest: south-facing perimeters, entrance thresholds and busy washrooms.

Rural business units near smaller places such as Bexon are frequently converted agricultural buildings. Old masonry beside new aluminium, timber and plasterboard gives plenty of joints between materials that move differently.

We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

Cost factors for sealant joints

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

  • Distance, for remote addresses
  • The site’s rules and procedures
  • How accessible the joints are
  • How much existing material needs removing

The product called for affects the cost, and so does the preparation, from cutting out to priming and backing rod. Access, phasing and site rules also count.

Before you send an enquiry

It doesn’t need to be a full survey. A few details are enough to get going:

  • Clear photographs of the problem areas
  • Any specification or named product
  • Anything awkward about access or site hours
  • Your programme or deadline

Need a figure for a tender or a budget? We’ll quote against your scope and drawings you can plan around. If you have questions first, give us a call on 01277 525 020 or email the details over.

What we’re called out for in Bexon

A good share of the joints we inspect were topped up instead of being renewed. New silicone has nothing to key into so it soon peels and traps moisture against the joint. By the time it shows, there can be two or three layers to cut out.

Site and facilities staff are often the first to spot these:

  • Water staining near frames, panels or ceilings
  • Shrunken sealant along kitchen worktops and splashbacks
  • Frame mastic that has hardened and come away from the wall
  • Layers of sealant, all of them failing

Offices at parks like Kent Science Park, 0.9 miles to the north-east of Bexon, have receptions, kitchens and glazed partitions where a tidy joint matters.

  • Which product they’ll use, and why it suits the joint
  • Proof of insurance

How to choose a sealant contractor

Common questions from Bexon clients

Can you work at a site such as Kent Science Park, by Bexon?

Yes. We cover Bexon and the area around it, including industrial estates, business parks and retail parks such as Kent Science Park. A few photos and the unit address let us price the work.

Can you match sealant colours for premises in Bexon?

Yes. Colour matching to frames, cladding, stone and shop-fit finishes is a regular part of the work. The quote lists the colours the product is made in.

How long does a typical visit take?

We plan the time on site around your programme and access. You will have an expected duration with the quote.

What guarantee do you give on resealing?

Our workmanship is guaranteed for 12 months. We are fully insured for public liability as well.

Do you hold CHAS accreditation?

Yes. We’re CHAS accredited, we’re a Constructionline member and we use CSCS-carded applicators.

How do you choose the sealant?

A specification, where there is one, decides it. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

Can you follow the specification on our project?

Yes. The specification and the manufacturer’s installation guidance are what we work to.

What the job involves on each surface

Window and door perimeters

Where frames meet the surrounding wall, sealant is the weather line. We remove the old seal, prepare the faces, fit backing where needed and seal again with a product chosen for both the frame and the wall.

Commercial kitchens and tea points

A smooth, continuous joint is easier to keep clean, which matters when environmental health officers look at a kitchen. Work is timed around the hours you give us so the kitchen isn’t out of use longer than needed.

Why deal with it now?

Sealant is often treated as an afterthought by the trade that fitted the element. A specialist applicator takes care of product choice, joint depth and preparation, and they’re where most failures begin. You notice the difference years later, not on the day. One visit to deal with every failing joint makes more sense than several trips to a place like Bexon. Photos of every joint help us quote for the whole job.

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

Why clients in Bexon choose us

  • Fully insured
  • Colour agreed before work starts

Our process

Inspect, seal, sign off: every visit follows that pattern. First comes an inspection and agreement on scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. If others near Bexon need work, visits can be combined. You’ll have a fixed quote before work starts.

  1. Send details through our quote form, or ask for a site visit.
  2. The cause is diagnosed and the scope priced as a fixed quote.
  3. Where parts of the building must stay open, the work is phased.
  4. Old sealant is cut out completely, never sealed over.
  5. A suitable product for each joint goes in at the right depth and is tooled.
  6. We check the work with you, and the 12-month guarantee starts.

Getting the site ready

  • Clear stock, furniture or equipment away from the joints
  • Warn occupants and staff about the work
  • Point out parking and an unloading spot

Getting a fixed quote

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. Smaller jobs need nothing more than photographs and a few notes.
