About our commercial sealant contractors in Dedham Heath

On older buildings, particularly those put up before 2000, some old mastics and sealants may contain asbestos. Before anything is cut out, we ask for the asbestos register or survey, because the duty to manage asbestos sits with the dutyholder. Anything suspect is left alone until it has been tested (removing asbestos-containing materials isn’t something we do). If you have untidy joints in a reception, shop floor or lobby and gaps behind commercial kitchen worktops and sinks, we can help, whatever the surface. Searching for sealant specialists in Dedham Heath? Mastic Doctor has worked for contractors, FMs and building owners since 2005, CHAS accredited and a Constructionline member.

Quotes for commercial sealant in Dedham Heath can come from photographs and a joint schedule, or from a walk-round, and the scope is set out in writing.

In and around smaller places such as Dedham Heath, the commercial buildings we’re asked about are often pubs, shops, village halls and barns converted to offices. Kitchens, toilets and window frames in all of them need resealing sooner or later.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

Honest limits

Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be any of the following:

  • Cracking that needs a structural engineer to look at it
  • Water from a services leak rather than a joint
  • Broken glass or blown double-glazed units

If in doubt, ring 01277 525 020 or email a schedule or drawings and we’ll say what we think.

Surfaces we seal

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

What affects the price in Dedham Heath

Quotes vary with the job. It mainly depends on:

  • Site requirements such as inductions and permits
  • How much there is to seal
  • Specialist products, such as fire-rated or hygienic sealants
  • How accessible the joints are

Larger quantities, tricky access or phasing all shape the price. So do site requirements such as inductions and permits.

Sending details for a quote

To price the job accurately, we need a clear picture of the site. Useful things to include:

  • Whether an asbestos survey exists
  • Approximate linear metres or a joint schedule
  • Access details, including height
  • Your programme or deadline

The quickest route to a quote is a few photos and the site postcode. Send them through the quote form, or give us a call on 01277 525 020 or email drawings and photos if you’d rather talk the job through.

Maintenance after handover

For the best life from the joints:

  • Look at the sealant around anything that has been moved or replaced
  • Respect the cure time before reopening an area
  • Act on the first lifting edges rather than waiting
  • Note dates and locations of sealant work for future planning

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 ring 01277 525 020 or use the quote form for a quote.

Each spell of wet weather pushes more water through an open joint. Behind a panel or frame, that water can sit unseen for a long time. Catching it at the sealant stage avoids the bigger repair.

Diagnose, treat, sign off

On arrival, we report to your site contact and complete whatever induction the building runs. Everything around the joints gets protected before anything is cut or cleaned, and the work normally takes anything from part of a day on a short run of joints to several weeks on a large phased package. Jobs in and around smaller places like Dedham Heath are usually planned as a single visit, so we ask for photographs and rough sizes first. Then the right materials arrive with us.

  1. You send photos, drawings or a list of the joints and areas involved.
  2. We work out why the joints have failed and fix a quote for the agreed scope.
  3. We plan around your site hours and access windows, phasing the work where areas have to stay in use.
  4. The failed bead is removed and the joint faces cleaned until they’re sound and dry.
  5. The depth is set, primer is used where the maker calls for it, and the fresh bead is applied and tooled.
  6. We walk the completed areas with you and sign them off under the 12-month guarantee.

What we need from you

  • Arrange parking or a loading space
  • Send asbestos survey details if the building is pre-2000
  • Point out any areas we must not close

Sealant on show in Dedham Heath’s commercial buildings

Rainfall across the South East, Dedham Heath included, is lower than in many parts of the UK. Even so, outside sealing waits for a dry joint, and cold, damp mornings can delay it. Dedham Heath has a number of hotels close by, all within 2 miles. Hotel refurbishments are where a matched sealant colour earns its place: bathroom, bar and reception joints have to sit with the finishes.

If you have premises on more than one site, say at Martells Industrial Estate and Blue Barns Business Park, one contractor and one quote can cover both. Premises within reach of Manningtree station (to the east of Dedham Heath) often have busy frontages where joints are seen by everyone passing. If you run a unit on an estate such as Martells Industrial Estate, 2.1 miles to the south of Dedham Heath, the trade counter, offices and staff facilities have joints to look after as well as the warehouse.

Questions we are asked in Dedham Heath

Is Dedham Heath too far out for you?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

Must a hotel around Dedham Heath close while you work?

Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. Housekeeping and our team agree each day’s rooms.

Do you check for asbestos before removing sealant?

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 if something is suspected, work stops until it’s tested.

Do you work for facilities managers and managing agents?

Yes. Use our quote form to send the site details, or phone or email us, and tell us what site paperwork you need.

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.

How is commercial sealant work priced?

Price depends on joint lengths and widths, how much removal is involved, the product, access and phasing. For a fixed quote, send details through our quote form.

Do you seal on top of existing sealant?

No. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

Leave it or put it right?

Before budgeting for new frames, cubicles or worktops, check whether it’s just the sealant. In many cases the element is fine and only the seal around it has given up. Resealing usually costs far less than renewal, and we’ll say so if the frame or fitting is life-expired. For buildings around smaller places like Dedham Heath, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Renewing joints in good time avoids the problem.

Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.
