About our commercial sealant contractors in East Mersea

Most commercial buildings carry hundreds of metres of sealant that nobody thinks about until it fails, and in an occupied building failure usually announces itself as a stained ceiling or an unhappy tenant. We are commercial sealant applicators for FMs, managing agents, landlords and contractors looking after property in East Mersea. Our job is to diagnose the failure, remove the old bead and seal again using a product chosen for the movement and exposure. We work on kitchen worktops and splashbacks, movement joints in walls and floors and floor and threshold joints, and the failures we’re asked to look at most are window and door perimeter joints that have cracked open and shrunken sealant along kitchen worktops and splashbacks. A specialist sealant contractor works differently from a general builder: in East Mersea, that means joint design, primers and backing rod as standard.

We price commercial jobs in East Mersea from photos, drawings or a site visit, and the scope is set out in writing.

Work in smaller places such as East Mersea 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.

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

How the job changes by surface

Shop fronts and retail fit-outs

Most shops can’t close for a reseal. Tell us your trading hours and access windows and we’ll plan around them.

Window and door perimeters

Inside, cracked sealant around frames and window boards is common. We use a paintable product where decorating follows and a silicone where it doesn’t.

Looking after the joints

A few simple habits keep the new joints working:

  • Add sealant to the planned maintenance inspection list
  • Have extract fans checked so wet areas dry out
  • Report cracked or peeling sealant early
  • Respect the cure time before reopening an area

We stand behind the workmanship with a 12-month guarantee. Keep the handover details with your O&M or maintenance records, and tell us if a joint we sealed gives trouble within that time.

Sealant installed at the same time usually fails in sequence. A few splits this year normally mean more next year, so it makes sense to look at the wider elevation or block. We’ll tell you which sealant joints need doing first and which can wait.

For managing agents and facilities managers

Whether you are a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

Main contractors use us as their sealant subcontractor. Programme, specification and site rules come first, with CSCS-carded applicators on site.

What East Mersea’s businesses ask us to seal

East Mersea lies within about 2 miles of the sea. For shops, hotels and offices, that means frontage and frame joints that weather faster than they would inland. We choose a product rated for the exposure, then confirm the colours available for it. East Mersea is about 50 miles from central London. The commuter belt holds a great many offices, retail parks and business parks. Occupiers with several premises in the region tend to prefer one contractor and one point of contact.

For premises near Alresford station (4.2 miles north of East Mersea), footfall is part of the plan: work is phased so shops and offices keep trading. On a business park such as Waldegraves Business Park, 1.7 miles south-west of East Mersea, sealant work tends to follow fit-outs: receptions, tea points, washrooms and frame perimeters.

East Mersea is about 7 miles west of Clacton-on-Sea, in Essex. Commercial clients in East Mersea use us for work on sealant joints. We work across 644 places in Essex, from busy centres to rural villages. There’s a separate page for London, roughly 50 miles from East Mersea.

We cover the CO5 postcode districts for sealant joints. Buildings on East Road, Shop Lane and Broman's Lane are within our area. If your building is just outside East Mersea, we cover Barrow Hill (2 miles west), Brightlingsea (2 miles north-east), Point Clear (2 miles east), West Mersea (3 miles west) and Lee-over-Sands (3 miles south-east). Bigger towns within reach include Colchester (8 miles north-west), Clacton-on-Sea (7 miles east), Maldon (14 miles west), Witham (15 miles west), Harwich (15 miles north-east) and Camulodunum (8 miles north-west).

What’s near East Mersea

We work on buildings around Dog And Pheasant Public House. East Mersea’s nearest station is Alresford station, about 4.2 miles north of the centre. For a walk, there’s Fingringhoe Wick.

Your questions answered

Is East Mersea too far out for you?

No. Places such as East Mersea are covered as much as the big towns. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.

Will you take on work at estates like Waldegraves Business Park, close to East Mersea?

Yes. Estates, retail parks and business parks around East Mersea, Waldegraves Business Park among them, are all within reach. Send details of the unit and the work through our quote form for a quick quote.

Which sealant will you use?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Could the old sealant in an older building contain asbestos?

In buildings from before 2000 in particular, some old mastics and sealants may contain asbestos. We ask to see the asbestos register or survey before disturbing old sealant, and anything suspect is left until it has been tested.

Is your work guaranteed?

Our workmanship on each job is backed by a 12-month guarantee. We are fully insured for public liability as well.

Do you work to architects’ specifications?

Yes. Send it with your enquiry, and we will price the work to it, flagging anything that needs clarifying.

Will your applicators have CSCS cards?

Yes. If you need card details for site access, tell us and we’ll confirm them with the quote.

When something else is needed

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 call the office on 01277 525 020 or email drawings and photos and we will tell you honestly before you book.

What we seal

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

What sets the cost

What shapes the price:

  • Site requirements such as inductions and permits
  • Travel to remote or island sites
  • Whether the work must be split into stages
  • Removal of failed or old sealant

We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

Details that help us quote

A few photographs plus some basic facts will normally do. Please tell us:

  • Whether an asbestos survey exists
  • What the building is and how it’s used
  • Any specification or named product
  • How the joints are reached, and at what height

Send details, get a quote, we seal, guaranteed: that’s how every job runs. To take the first step, give us a call on 01277 525 020 or email us.

How a job runs

Occupied buildings need a little choreography. The work area is signed and kept contained, with routes through the building left open and work section by section so the rest of the building stays in use. Smaller jobs around East Mersea can be grouped with others nearby. A fixed quote is given before anything starts.

  1. Site photos, drawings or a visit tell us what’s there and how it has failed.
  2. You get a fixed quote covering removal, preparation and the new sealant.
  3. We agree the order of work, access windows and site hours with you.
  4. Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
  5. Depth is set with backing, then the sealant is applied, tooled and the area tidied.
  6. We hand back each area with its cure time and our 12-month guarantee.

Preparing the site

  • Send any specification or drawings in advance
  • Point out any areas we must not close
  • Clear stock, furniture or equipment away from the joints

Quotes

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price against exactly what is specified. For smaller jobs, photographs and a description will do.
