Commercial sealant contractors in Hammer

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

For managing agents and facilities managers

Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Sites in Hammer can sit alongside others in a wider programme.

Main contractors use us as their sealant subcontractor, on new build and refurbishment alike. Programme, specification and site rules come first, and our applicators hold CSCS cards.

About our commercial sealant contractors in Hammer

Sometimes a split bead is a symptom rather than the cause. Water at a window perimeter might be coming from the frame, the cill or the wall behind while a movement joint that keeps tearing may simply be too narrow for the job. Part of the job is telling you when the fix is something other than sealant, so budgets go where they’ll do some good. If you are dealing with leaks that seem to come through a sealant line and frame sealant that has cracked, shrunk or pulled away, we can put it right, on kitchen worktops and splashbacks, window and door perimeters and floor and threshold joints alike. Most enquiries from Hammer start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

Occupied buildings in Hammer need the work phased: we agree the order with you and hand back each area with its cure time.

A job in a smaller place like Hammer is typically a single building. We will want a full list and photos first, so the right products come on the day and nothing waits for a second trip.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and the quote explains what it covers.

When something else is needed

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Water from a services leak rather than a joint
  • Removing asbestos-containing materials (a licensed or specialist contractor’s job)
  • Cracking that needs a structural engineer to look at it

Not sure which it is? You can speak to us on 01277 525 020 or email us and we’ll tell you honestly.

Joints and surfaces we work on

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

On site: what to expect

We schedule the visit to fit the site hours and access windows you give us. On the day, the work area is kept contained and tidy, and we check in with your contact before moving on to each new area. Jobs in and around smaller places like Hammer are normally planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  1. First, details come to us: photographs, drawings or a schedule of the areas, and a site visit is booked where it helps.
  2. Next comes a diagnosis and a fixed quote.
  3. Before anything is cut out, we agree access, timings and sequence.
  4. Failed sealant is cut out and each joint cleaned back to sound, dry faces.
  5. We fit backing to the right depth, prime where specified and lay the new bead.
  6. Finished joints are checked with you and handed over with our 12-month guarantee.

Before we start on site

  • Tell us what induction or permit system the site runs
  • Send any specification or drawings in advance
  • Send your site hours and access windows

Advice

Questions about Hammer

Is Hammer too small for you to travel to?

No. Places such as Hammer are covered as much as the big towns. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Does your area include sites such as Kings Road Industrial Estate, near Hammer?

Yes. Estates, retail parks and business parks around Hammer, Kings Road Industrial Estate among them, are all within reach. A few photos and the unit address let us price the work.

Is failed sealant stripped out, or sealed over?

Every failed bead is cut out completely. New sealant can’t grip the old bead, so laying over it never lasts.

Do you work for facilities managers and managing agents?

Yes. FMs, managing agents and landlords are among our regular clients, alongside main contractors. We can work to your instruction process and site rules.

Who decides which product is used?

The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.

Can you supply RAMS and insurance details?

Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote. We hold CHAS accreditation and Constructionline membership and carry five million pounds of public liability insurance.

When can the area be used after sealing?

That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we will confirm the curing time on the day.

Why it’s worth doing now in Hammer

Sealant is often treated as an afterthought by the trade that fitted the element. A specialist applicator takes care of product choice, joint depth and preparation, the three things that decide how long a joint lasts. You notice the difference years later, not on the day. Older rural buildings around Hammer move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

What a job costs comes down to how many linear metres there are, what has to come out first and how the joints are reached. Call for a quote when you’re ready.

Why appoint us

  • Matching to RAL references, product permitting
  • Fixed quotes based on photographs, drawings or a visit
  • Coloured sealants to suit the setting, where available
  • Colours confirmed for the specified product

Looking after the joints

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

  • On pre-2000 buildings, share the asbestos information before work starts
  • Check joints after other trades have worked nearby
  • Log reseals in the O&M or maintenance records
  • Make sure ventilation in wet areas is switched on and working

Later works are the usual way new joints get damaged. When fittings are moved or cabling added, the sealant nearby is easily disturbed, and it’s easy to forget to reseal afterwards. Where work has disturbed a joint, just ring 01277 525 020 or use the quote form for a quote.

A failed external joint lets water in every time it rains. Behind a panel or frame, that water can sit unseen for a long time. Resealing early keeps the problem in the sealant and out of the building.

Surface by surface

Facade and cladding joints

Panel joints on cladding and rendered facades open and close with the temperature. They need a sealant with the right movement capability, laid at the right depth. We confirm the access in place before we quote.

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.

Commercial sealant contractors in Hammer: the local picture

Three care or nursing homes sit less than 2 miles from Hammer. Kitchens and communal rooms in care settings are cleaned constantly, so their joints need to be smooth and sound; colours can be chosen to suit the interior. At about 40 miles from central London, Hammer is within reach of the capital. The South East around the capital has large numbers of business parks, offices and retail centres, especially around the motorway corridors. Firms with branches across the South East can use one contractor for every site.

Shops and cafés around stations like Haslemere station (1.5 miles east of Hammer) trade from early, so work is timed around them.

If you have premises on more than one site, say at Kings Road Industrial Estate and Unicorn Trading Estate, one contractor and one quote can cover both.
