Sealant applicators in Brunswick

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, since managing asbestos is the dutyholder’s responsibility. Anything suspect is left alone until it has been tested. We work on external facade joints, floor and threshold joints and movement joints in walls and floors, and the usual reasons a site gets in touch are gaps behind commercial kitchen worktops and sinks and expansion joints with the sealant torn out. Most enquiries from Brunswick start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Occupied buildings in Brunswick need the work phased: washrooms in turn, floors in sections and entrances kept open.

Places like Brunswick 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.

A 12-month guarantee applies to all our work in Brighton and Hove. Should something we installed fail, give us a call on 01277 525 020 or email drawings and photos and we will come back to it.

What happens if it’s left?

It can be tempting to hold sealant work back until the next refurbishment. For internal joints that are only cosmetic, that can make sense, but external and wet-area joints that already leak shouldn’t wait. We can seal the urgent joints now and leave the rest for the programme. A failed joint lets water into a building whatever its size. Early resealing avoids the damage that follows a leak.

There’s no price list, since every building and every scope is different. Call for a quote.

For managing agents and facilities managers

As a CHAS accredited contractor and Constructionline member, we are straightforward to vet for your supplier list. We are fully insured, and our insurance certificate can go with the quote.

For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules.

Should maintenance staff do it?

What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are easy to get wrong without experience.

Certain joints really need a specialist: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.

How the quote is worked out

Each job is priced on its own details. The things that drive the figure:

  • Travel to remote or island sites
  • The total length or number of joints
  • Which sealant the job calls for
  • Backing rod, priming and other preparation

The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site requirements come into it too.

What to include in your enquiry

For an accurate fixed quote, we need a clear picture of the site. Useful things to include:

  • Anything awkward about access or site hours
  • The type of building and who uses it
  • Any dates the work must fit around
  • Specification clauses that apply

The quickest route to a quote is a few photographs and the site postcode. Upload them with the quote form, or speak to us on 01277 525 020 or use the quote form to discuss it first.

Your questions answered

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

Rarely. Rooms or floors are done in turn, so the rest of the hotel keeps trading. Tell us your quiet periods and access windows and we’ll plan around them.

Is Goldstone Retail Park, near Brunswick, within your area?

Yes. We cover Brunswick and the area around it, including industrial estates, business parks and retail parks such as Goldstone Retail Park. Send details of the unit and the work through our quote form for a quick quote.

Will the building have to shut during the work?

Phased work can be planned so areas stay in use. We plan around the site hours and access windows you give us.

How soon can the area be used again?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, so we will confirm the curing time on the day.

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.

Do you seal on top of existing sealant?

No, never. Overlaying old sealant is a frequent cause of early failure, so it all comes out first.

How do we get a quote?

Photos, drawings or a schedule of the joints are usually enough to start through our quote form. Where we need to see it, we will arrange a site visit, then send a fixed quote.

Our process

The first thing on site is a walk round with your contact, 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 job in Brunswick, the main thing is a clear picture of the work. You’ll then get a fixed price for the work.

  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. Work is phased around your occupiers where areas need to stay in use.
  4. Every failed bead is removed rather than covered.
  5. A suitable product for each joint goes in at the right depth and is tooled.
  6. A final walk-round, then the 12-month guarantee applies.

Preparing the site

  • Send asbestos survey details if the building is pre-2000
  • Point out parking and an unloading spot
  • Make sure the joints can be reached

Quotes

If there’s a specification, drawings or a tender package, send it with your enquiry, and we will price the work to it. For smaller jobs, photographs and a description will do.

Advice

Honest limits

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Structural cracks or movement the joints weren’t designed for
  • Leaking roofs, gutters or flat-roof membranes (those need a roofer)
  • Faulty windows rather than failed perimeter sealant

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

Where we work in Brunswick

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

Shops, offices and hotels in and around Brunswick

With the shore within about 1 mile, Brunswick counts as a coastal location. For shops, hotels and offices, that means frontage and frame joints that weather faster than they would inland. We choose a product rated for the exposure, then confirm the colours available for it. There are four care or nursing homes within about 2 miles of Brunswick. 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.

For a shop at a centre such as Churchill Square, less than half a mile east of Brunswick, tidy joints at counters and displays matter as much as the fixtures. A business with units at Goldstone Retail Park and Freshfield Industrial Estate needn’t use two contractors for its sealant. For a retailer at a site such as Goldstone Retail Park, 1.3 miles north-west of Brunswick, the joints clients see are as much part of the fit-out as the shelving.

Brunswick is about 1 mile south-west of Brighton, in Brighton and Hove. Anywhere in BN1, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. We work across 29 places in Brighton and Hove, from busy centres to rural villages.

We take on sealant joints across the BN1, BN3 and BN50 postcode area. Buildings on Farm Road, York Road and Powis Road are within our area for sealant joints. Just outside Brunswick, we also work in Seven Dials (1 mile north-east), West Hill (1 mile north-east), Prestonville (1 mile north), Hove (1 mile north-west) and Carlton Hill (1 mile east).
