Commercial sealant contractors for businesses in Highcliffe

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

Commercial mastic work in Highcliffe

Pricing a commercial reseal is a short process. Our quote form takes photos, drawings or a schedule of the areas and you can also speak to us on 01277 525 020 or email drawings and photos to talk it through. Where the photographs don’t tell the full story, we arrange a site visit, and a fixed quote for the agreed scope follows. We work on external facade joints, kitchen worktops and splashbacks and window and door perimeters, and what we are called in for most is hardened, chalky sealant on south-facing or exposed elevations and gaps behind commercial kitchen worktops and sinks. A specialist sealant contractor works differently from a general builder: in Highcliffe, that means joint design, primers and backing rod as standard.

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

Places like Highcliffe tend to have a handful of commercial buildings: a local shop, a pub or restaurant, a surgery, a school and the odd office or workshop. They’re not big jobs one by one, but their joints need the same preparation as anywhere.

Our workmanship is guaranteed for 12 months, in Highcliffe as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Commercial premises in Highcliffe

Plenty of hotels sit less than 2 miles from Highcliffe. In hotels, sealant shows everywhere, from bathroom joints to reception counters, so colour and a clean finish matter; work is planned so the hotel keeps trading. Two care or nursing homes sit less than 2 miles from Highcliffe. Care homes need tidy, cleanable joints in kitchens, corridors and communal rooms.

If you run a unit on an estate such as Bar End Industrial Estate, which lies south-west of Highcliffe, the trade counter, offices and staff facilities have joints to look after as well as the warehouse. A hotel such as Wessex Hotel, 0.5 miles to the north-west of Highcliffe, shows how much sealant a hospitality building has on show, from bathroom joints to the bar. Premises within reach of Winchester station, 1.1 miles to the north-west of Highcliffe, often have busy frontages where joints are seen by everyone passing.

Honest limits

Being straight saves everyone time. Fresh joints won’t solve:

  • Water from a services leak rather than a joint
  • Roof leaks that only look like a joint problem
  • Old mastic that tests positive for asbestos

If in doubt, speak to us on 01277 525 020 or email the details over and we will say what we think.

What we seal

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

Cost factors for sealant joints

Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:

  • Whether the work must be split into stages
  • How accessible the joints are
  • The site’s rules and procedures
  • The product specified

We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote.

Before you send an enquiry

However big the job, these details speed things up:

  • Rough lengths or quantities, or drawings if you have them
  • What the building is and how it’s used
  • Anything awkward about access or site hours
  • A wide shot and a close-up of the area

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

How a job runs

We begin with a short walk round with whoever looks after the building, agreeing which joints are in scope, where to start and what must stay open. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a site in Highcliffe, we plan so the whole job is done in one go where possible. Clear photographs and measurements help us bring the right products.

  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.

Getting the site ready

  • Point out any areas we must not close
  • Tell staff and tenants when we will be in
  • Send your site hours and access windows

Highcliffe: questions and answers

Will our hotel in Highcliffe 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.

Is Highcliffe off your patch?

No. Small places get the same service as large ones. Our area covers London and the South East counties. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Does the weather affect the work?

It can, for external work. Sealant won’t bond properly to a wet or frosty joint, so we watch the forecast and rearrange outside work if we have to. Indoors, the weather is rarely a problem.

Is it fine to apply new sealant on top of old?

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

What about asbestos in old mastic?

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.

Are you CHAS accredited and on Constructionline?

Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.

Will your applicators have CSCS cards?

Yes. Should the site need card details in advance, tell us and we will confirm them with the quote.

General trades versus a specialist

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are easy to get wrong without experience.

Surface by surface

Shop fronts and retail fit-outs

Shop fits put sealant right in front of clients. Joints around counters, displays and shopfront frames have to look tidy as well as seal. We will confirm the colours available for the specified product.

Fire-rated seals where specified

Where the specification calls for fire-rated or intumescent sealant around service penetrations or linear gaps, we install it to the product’s tested detail. The design and sign-off of fire stopping belong to the designer and building control, and we install to the specification.
