Commercial sealant contractors for Steep sites

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Doing it in-house

Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.

Sealant applicators in Steep

Sealant joints are easy to overlook until one lets water in, and in an occupied building failure normally announces itself as a stained ceiling or an unhappy tenant. We’re commercial sealant applicators for FMs, managing agents, landlords and contractors with sites in Steep. 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, washrooms and tea points and movement joints in walls and floors, and the failures we are asked to look at most are layers of sealant, all of them failing and shrunken sealant along kitchen worktops and splashbacks. Searching for sealant specialists in Steep? We’ve been sealing commercial buildings since 2005.

If you look after more than one building near Steep, the work can be planned as one programme, so standards and paperwork match across every site.

In and around smaller places such as Steep, the commercial buildings we are 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.

The 12-month guarantee is for workmanship rather than wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Keeping the joints sound

Problems stay small when the joints are checked regularly. Specifically:

  • Note dates and locations of sealant work for future planning
  • Keep barriers up until the new sealant has cured
  • Put external and wet-area joints on a regular inspection round
  • Act on the first lifting edges rather than waiting

Put sealant on the planned maintenance checklist. Regular checks pick up small failures before they become leaks, especially on exposed elevations and in washrooms. If anything looks wrong, speak to us on 01277 525 020 or email us with a photo.

A failed external joint lets water in every time it rains. It can run into cavities, insulation and internal finishes long before anyone sees a stain. Catching it at the sealant stage avoids the bigger repair.

On site: what to expect

Inspect, seal, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and the job ends with a walk round and sign-off. For a building around Steep, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  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. Every failed bead is removed rather than covered.
  5. Each joint gets a suitable sealant, laid to depth and tooled.
  6. We check the work with you, and the 12-month guarantee starts.

Preparing the site

  • Make sure the joints can be reached
  • Send asbestos survey details if the building is pre-2000
  • Warn occupants and staff about the work

Quotes

Send us photos, drawings or a joint schedule are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

How the quote is worked out

The price varies from site to site. It mainly depends on:

  • How much there is to seal
  • Phasing around occupants
  • Induction, permit and paperwork requirements
  • The product specified

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

What we need to price the job

Diagnosis starts before we arrive. Tell us:

  • Asbestos survey details if the building is older
  • Photos of the joints, close up and from further back
  • Drawings or a marked-up plan, if available
  • Any dates the work must fit around

A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or phone 01277 525 020 or use the quote form to discuss it first.

Your questions answered

Can you work at a site such as Upper Adhurst Industrial Park, by Steep?

Yes. Estates, retail parks and business parks around Steep, Upper Adhurst Industrial Park among them, are all within reach. A few photographs and the unit address let us price the work.

Will our hotel in Steep need to close for the work?

Almost never. The work is phased so most rooms stay available. Housekeeping and our team agree each day’s rooms.

Which site documents can you send us?

Let us know your requirements when you ask for a price, and the paperwork is confirmed with the quote. From you, we will need the asbestos information for older buildings and any site rules.

How is commercial sealant work priced?

Photos, drawings or a schedule of the joints are normally enough to start. Where we need to see it, we’ll arrange a site visit, then send a fixed quote.

When is resealing likely to be due?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

Are you CHAS accredited and on Constructionline?

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

Do you check for asbestos before removing sealant?

Some older mastics did contain asbestos. So we check the register first and stop work on anything suspect until it’s tested. HSE guidance on asbestos is a useful reference.

Surface by surface

Shop fronts and retail fit-outs

Most shops can’t close for a reseal. We plan around the access windows the store gives us.

Movement joints in walls and floors

Brickwork, blockwork and floor slabs all have movement joints that need a flexible seal. Failed seals let grit and water in, and the edges start to suffer. The joints are resealed using a sealant matched to the movement and any traffic.

Working on commercial sites near Steep

Steep has a number of hotels close by, all within 2 miles. In hotels, sealant shows everywhere, from bathroom joints to reception counters, so colour and a clean finish matter, with rooms done in turn while the rest stay let. Steep has two named business or industrial parks inside a 3-mile radius. Sites like these see regular refits, with shopfronts, offices and staff areas to seal, often in a colour the occupier specifies.

Trade counters and showrooms on estates such as Upper Adhurst Industrial Park, 1.8 miles east of Steep, need neat joints where customers see them. A business with units at Upper Adhurst Industrial Park and Ham Barn Business Park needn’t use two contractors for its sealant. Offices and shops close to stations such as Petersfield station, 1.4 miles to the south of Steep, tend to be busy all day, so sealant work is planned around opening hours.
