Commercial sealant contractors in East Stourmouth, done properly

On older buildings, particularly those put up before 2000, some old mastics and sealants may contain asbestos. We ask to see the asbestos register or survey before old sealant is disturbed. If a material is suspected, work stops until it’s tested (removing asbestos-containing materials isn’t something we do). The enquiries we see most involve window and door perimeter joints that have cracked open and damp patches where an external joint has failed, across kitchen worktops and splashbacks, external facade joints and movement joints in walls and floors. Whether you call it commercial sealant work, mastic application or joint sealing, in East Stourmouth it comes down to the same thing: the right product in a properly prepared joint.

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

Business units in the countryside around places like East Stourmouth are often converted barns, stables or farmyards. Old masonry beside new aluminium, timber and plasterboard gives plenty of joints between materials that move differently, and a sealant colour that suits the building’s character is often part of the brief.

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

Aftercare for building managers

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:

  • Keep washroom and kitchen extraction working
  • Don’t let cleaning or traffic back on before the cure time is up
  • Check the asbestos register before anyone disturbs old sealant in an older building
  • Put external and wet-area joints on a regular inspection round

Keep an eye out for other trades after we have gone. When fittings are moved or cabling added, the sealant nearby is easily disturbed and the joint gets left open. Where work has disturbed a joint, just speak to us on 01277 525 020 or email the details over for a quote.

An open joint in a food area or toilet collects dirt and moisture that cleaning can’t reach. Cleanability is something environmental health officers pay attention to.

Diagnose, treat, sign off

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work typically takes part of a day on a small job and longer where several buildings or phases are involved, and our waste is bagged and taken away as we go. Jobs in and around smaller places like East Stourmouth are typically planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. First, details reach us through the quote form or a site visit.
  2. We diagnose the cause of failure and price a fixed scope.
  3. Work is phased around your occupiers where areas need to stay in use.
  4. Old sealant is cut out completely, never sealed over.
  5. Each joint gets a suitable sealant, laid to depth and tooled.
  6. A final walk-round, then the 12-month guarantee applies.

Before we start on site

  • Tell us what induction or permit system the site runs
  • Arrange parking or a loading space
  • Point out any areas we must not close

Advice

Work for main contractors and building owners

Whether you are a managing agent, a property factor or an owner’s representative: send details, get a fixed quote, we seal, guaranteed. Keys, access and contacts can be agreed in advance.

Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

How the job changes by surface

Fire-rated seals where specified

Intumescent and other fire-rated sealants go in at service penetrations and linear gaps to the maker’s tested details, where they are specified. Fire-stopping design and sign-off sit with the designer, fire engineer or building control; we install what’s specified.

Commercial kitchens and tea points

Kitchen joints along worktops, sinks, splashbacks and wall cladding collect grease and moisture. They’re degreased thoroughly before resealing, and a hygienic or food-safe sealant is used where food contact is possible.

Common questions from East Stourmouth clients

Is East Stourmouth too far out for you?

No. Small places get the same service as large ones. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.

Can you work at a site such as Monkton Business Centre, by East Stourmouth?

Yes. We cover East Stourmouth and the area around it, including industrial estates, business parks and retail parks such as Monkton Business Centre. Send details of the unit and the work through our quote form for a quick quote.

Do you work directly for building managers?

Yes. You can send details through our quote form, and we’ll confirm any paperwork you need with the quote.

When can the area be used after sealing?

The product and site conditions decide that. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.

Are you CHAS accredited and on Constructionline?

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

When is resealing likely to be due?

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 your work guaranteed?

It’s backed by our 12-month guarantee. Should a joint we sealed give trouble during those 12 months, let us know and we’ll look at it.

Honest limits

Our job is the joint, not everything around it. Sealant alone won’t deal with:

  • Roof leaks that only look like a joint problem
  • Faulty windows rather than failed perimeter sealant
  • Removing asbestos-containing materials (a licensed or specialist contractor’s job)

Not sure which it is? You can speak to us on 01277 525 020 or send details through our quote form and we will tell you honestly.

Joints and surfaces we work on

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

Signs you need commercial sealant contractors in East Stourmouth

External sealant takes a steady beating from the weather. UV hardens the surface while wind and rain work at the edges. Once it stiffens, the joint opens up at the next big temperature swing.

Any of the following is a good reason to get the joints checked over:

  • Shrunken sealant along kitchen worktops and splashbacks
  • Window and door perimeter joints that have cracked open
  • Water staining near frames, panels or ceilings
  • Sanitary sealant that has gone black and patchy

On a business park such as Monkton Business Centre, 2.3 miles north-east of East Stourmouth, sealant work tends to follow fit-outs: receptions, tea points, washrooms and frame perimeters.
