Sealant applicators in Eastrop

Some sealants used before 2000 can contain asbestos, so older stock needs a check first. Before anything is cut out, we ask for the asbestos register or survey, since managing asbestos is the dutyholder’s responsibility. If a material is suspected, work stops until it’s tested, and we don’t remove asbestos-containing materials ourselves. If you have sanitary sealant that has gone black and patchy and greasy, split joints in a kitchen or tea point, we can put it right. Most enquiries from Eastrop 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.

In an occupied building in Eastrop, the job is planned so areas stay in use: washrooms in turn, floors in sections and entrances kept open.

Small businesses near places like Eastrop frequently occupy converted farm buildings. Old masonry and timber meet new glazing and partitions in these buildings, and every junction needs a sealant that suits it.

Work we carry out in Hampshire comes with a 12-month guarantee. If an installation problem shows up, speak to us on 01277 525 020 or use the quote form and we’ll arrange a return visit.

When something else is needed

Before quoting, we check that sealant is the right answer. It isn’t the answer for:

  • Leaks from pipework, wastes or valves (that’s plumbing)
  • Broken glass or blown double-glazed units
  • Suspect materials that need testing and specialist removal

If in doubt, call 01277 525 020 or email drawings and photos and we’ll say what we think before you book.

What we seal

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

Our process

When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before anything is cut or cleaned, with the work itself typically taking a few hours to several days on most single sites, depending on joint lengths and access. What matters most for a job in Eastrop is a clear list of what needs doing. You’ll then get a fixed price for the work.

  1. Send details through our quote form, or ask for 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. 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.

Before we start on site

  • Agree which areas must stay open
  • Explain the parking and delivery arrangements
  • Tell us your opening times and when work is allowed

Advice

What Eastrop’s businesses ask us to seal

Two care or nursing homes sit less than 2 miles from Eastrop. In care settings, a neat joint at a kitchen worktop or a lounge window is part of keeping the place easy to clean; colours can be chosen to suit the interior. Plenty of hotels sit less than 2 miles from Eastrop. Hotel refurbishments are where a matched sealant colour earns its place: bathroom, bar and reception joints have to sit with the finishes; work is planned so the hotel keeps trading.

Premises within reach of Basingstoke station, less than half a mile north-west of Eastrop, often have busy frontages where joints are seen by everyone passing. Occupiers with premises at both Daneshill East Industrial Estate and Thornycroft Industrial Estate could have the sealant at each handled under one quote.

Looking after the joints

Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:

  • Don’t let cleaning or traffic back on before the cure time is up
  • Check joints after other trades have worked nearby
  • Add sealant to the planned maintenance inspection list
  • Make sure ventilation in wet areas is switched on and working

Brief your cleaning team on the joints that have been resealed. Abrasive pads, scrapers and some strong chemicals damage sealant surfaces, while a neutral cleaner and a soft cloth do no harm.

Movement joints that fill with debris stop working. With nothing soft to close against, the materials either side take the load and start to break up. That turns a sealant job into something bigger.

Questions about Eastrop

Will our hotel in Eastrop need to close for the 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.

Is a smaller place like Eastrop outside your area?

No. Places such as Eastrop are covered as much as the big towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Will you just go over the old sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.

Which sealant will you use?

If the job is specified, we follow the specification. If not, we choose for the movement, the surfaces and the conditions, in line with the manufacturer’s guidance.

Are you CHAS accredited and on Constructionline?

Yes. CHAS accredited, Constructionline member, and our applicators hold CSCS cards.

Can you handle sealant work across several sites?

Yes. We regularly take on multi-site work and planned maintenance programmes, priced site by site or as one programme.

How do you keep disruption to occupiers down?

Most of the buildings we work in stay occupied. We agree the order of areas, protect what’s nearby and close off only the section we’re sealing, until its cure time has passed.

How the quote is worked out

Before we quote, we look at:

  • Which sealant the job calls for
  • The site’s rules and procedures
  • Whether the work must be split into stages
  • Joint width, depth and condition

Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.

Before you send an enquiry

Diagnosis starts before we arrive. Tell us:

  • Access details, including height
  • Approximate linear metres or a joint schedule
  • Where the site is, with the postcode
  • Whether the building will be occupied during the work

We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To ask for one, speak to us on 01277 525 020 or send photos by email.

Common problems we fix in Eastrop

Resealing over the top is a false economy we come across often. New silicone has nothing to key into, so the top layer lifts, holds water and hides what’s going on. By the time it shows, there can be two or three layers to cut out.

These are often picked up first by site or facilities staff:

  • Black mould through washroom sealant that won’t clean off
  • A top-up bead over failed sealant, now lifting
  • Leaks that seem to come through a sealant line
  • Untidy joints in a reception, shop floor or lobby

In a retail centre such as The Malls, which lies north-west of Eastrop, new tenants mean new shop fits, and the sealant at counters, frontages and floor edges is part of the finish.

What to look for in a quote

  • How the joint faces will be prepared and primed
  • Is the sealant right for the movement and the substrate?
  • How they handle RAMS and site documents
  • Can the work be phased to keep areas open?

Our contractor checklist

Different surfaces, different methods

Commercial kitchens and tea points

A smooth, continuous joint is easier to keep clean, and cleanability is part of what an inspector looks at. Work is timed around the hours you give us so the kitchen isn’t out of use longer than needed.

Window and door perimeters

Where frames meet the surrounding wall, sealant is the weather line. We remove the old seal, prepare the faces, fit backing where needed and seal again with a product chosen for both the frame and the wall.
