Commercial mastic work in West Malling

Sealant joints are easy to overlook until one lets water in, and on a working site that normally 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 looking after property in West Malling. We find out why the sealant joints failed, take them out and seal again using a sealant that suits the joint. We work on external facade joints, kitchen worktops and splashbacks and window and door perimeters, and what we are called in for most is mouldy silicone around WCs, urinals and vanity tops and expansion joints with the sealant torn out. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in West Malling it comes down to the same thing: the right product in a properly prepared joint.

Multi-site clients with buildings in and around West Malling can put several sites on one programme, so standards and paperwork match across every site.

Around smaller places such as West Malling, small firms often work from converted barns, yards and rural units. Those conversions put new frames and partitions against old brick, stone or timber, so each joint needs a product chosen for both surfaces.

We sign every job off with a 12-month guarantee. The promise is simple: if our work fails within that year, we put it right.

Keeping the joints sound

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

  • On pre-2000 buildings, share the asbestos information before work starts
  • Deal with small splits before they become leaks
  • Have extract fans checked so wet areas dry out
  • Brief cleaning contractors to avoid scourers and blades on sealant

Keep an eye out for other trades after we’ve gone. When fittings are moved or cabling added, the sealant nearby is easily disturbed. Where work has disturbed a joint, just call the office on 01277 525 020 or email drawings and photos for a quote.

Movement joints that fill with debris stop working. With nothing soft to close against, the materials either side take the load and start to break up. At that point it’s a repair job rather than a reseal.

When to bring in a specialist

There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

What the job involves on each surface

Commercial kitchens and tea points

In kitchens, sealant lines at worktops, sinks and wall panels take heat, grease and daily cleaning. Proper degreasing comes before any new sealant, with a food-safe or hygienic product wherever food contact can happen.

Facade and cladding joints

Panel joints on cladding and rendered facades open and close with the temperature. The product has to suit the movement, and the depth has to be controlled with backing. Access, such as scaffold already up, is agreed before the price is fixed.

Your questions answered

Can you work at a site such as Kings Hill Business Park, by West Malling?

Yes, sites like Kings Hill Business Park are within our area, along with the rest of West Malling. A few photos and the unit address let us price the work.

Do hotels near West Malling have to close for sealant work?

Almost never. The work is phased so most rooms stay available. The plan is built around your bookings.

How long does a typical visit take?

It depends on the scope, but the work typically takes part of a day on a small job and longer where several buildings or phases are involved. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.

Is it OK to apply fresh sealant over existing beads?

Removal comes first, every time. After that come cleaning, primer where needed, backing and the new sealant.

Are you CHAS accredited?

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

How long will the new sealant last?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

Can you supply RAMS and insurance details?

We’ll confirm the paperwork you need, such as RAMS, an insurance certificate or CSCS details, with the quote. We are CHAS accredited and a Constructionline member, with five million pounds of public liability insurance.

  • Rough lengths or quantities, or drawings if you have them
  • When you need the work done
