Commercial sealant contractors for New Town sites

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

What New Town’s businesses ask us to seal

New Town has several hotels close by, all within 2 miles. Refits in hotels bring joints at vanity tops, bar counters and reception desks where the colour has to suit the scheme. At about 44 miles from central London, New Town is within reach of the capital. Business parks and retail centres are common around the capital’s motorway corridors. Firms with branches across the South East can use one contractor for every site.

Offices and shops close to stations such as Pangbourne station, 1.6 miles to the east of New Town, tend to be busy all day, so sealant work is planned around opening hours.

New Town is about 7 miles west of Reading, in West Berkshire. Any commercial site in New Town is covered, for single jobs and planned programmes alike. We work across 140 places in West Berkshire. Reading is covered too, around 7 miles from New Town.

Commercial sealant contractors for commercial buildings in New Town

On a commercial site, sealant turns up in more places than people expect: washroom fittings, kitchen worktops, window boards, partition heads and the line where floors meet walls. Externally it keeps rain out of frame perimeters, panel joints and movement joints. Our applicators work on both the inside and the outside of the building, picking the product for each location rather than one tube for everything. If you have frame sealant that has cracked, shrunk or pulled away and layers of sealant, all of them failing, we can put it right, on external facade joints, washrooms and tea points and kitchen worktops and splashbacks alike. Whoever orders the work in New Town, the brief is typically the same: a clear scope, tidy work and joints that don’t fail again.

In New Town, as anywhere, the first joints to go are normally the ones that work hardest: south-facing perimeters, entrance thresholds and busy washrooms.

Business units in the countryside around places like New Town are often converted barns, stables or farmyards. Old masonry beside new aluminium, timber and plasterboard gives plenty of joints between materials that move differently.

We stand behind the joints we seal with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Questions we are asked in New Town

Can you match sealant colours for premises in New Town?

Yes, we can normally get close to most finishes from the product’s colour range. Available colours for the product are confirmed with the quote.

Does a hotel in New Town need to shut while its sealant is renewed?

In most cases no closure is needed: we work room by room or floor by floor. Housekeeping and our team agree each day’s rooms.

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

No. We cut the old material out and clean the joint back before sealing, because fresh silicone will not bond with aged silicone.

Can weather delay the job?

Outside, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Inside work is seldom held up.

Could the old sealant in an older building contain asbestos?

It can, on some older buildings. So we check the register first and stop work on anything suspect until it’s tested. HSE guidance on asbestos is a useful reference.

How many days will you need on site?

It depends on the scope, but the work usually takes part of a day on a small job and longer where several buildings or phases are involved. Larger or phased jobs take longer, and we will give you a timescale with the quote.

Can you take on work for an FM or managing agent?

Yes. You send the details, we return a fixed quote, and the job is done and signed off, with a 12-month guarantee on the workmanship.

Quoting for work in New Town

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

  • The total length or number of joints
  • Joint width, depth and condition
  • Distance, for remote addresses
  • Access and working height

The specified product makes a difference, and so does the preparation, such as cutting out, priming or new backing rod. Access, phasing and site rules also count.

What to include in your enquiry

However big the job, the same details help:

  • Access details, including height
  • A wide shot and a close-up of the area
  • Whether the building will be occupied during the work
  • Any specification or named product

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.

Diagnose, treat, sign off

On arrival, we sign in, go through any site induction and check how permits are handled. Everything around the joints gets protected before anything is cut or cleaned, with the work itself typically taking anything from part of a day on a short run of joints to several weeks on a large phased package. If others near New Town need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. You send photos, drawings or a list of the joints and areas involved.
  2. We work out why the joints have failed and fix a quote for the agreed scope.
  3. Site hours, access windows and the order of areas are agreed before we start.
  4. We strip the failed bead and prepare both faces of the joint.
  5. Backing and primer go in where needed, then the chosen sealant is applied and tooled.
  6. Each area is inspected, signed off and backed by our 12-month guarantee.

What we need from you

  • Tell staff and tenants when we will be in
  • Make sure the joints can be reached
  • Agree which areas must stay open

Advice

When to call us in New Town

Resealing over the top is a false economy we come across often. Fresh sealant won’t stick to the old bead underneath, so the top layer lifts, holds water and hides what’s going on. Getting back to a clean joint then means removing every layer.

Most enquiries start with one or more of the following:

  • Movement joints packed with grit and debris
  • Messy, uneven beads from earlier work that let the building down
  • Layers of sealant, all of them failing
  • Frame mastic that has hardened and come away from the wall

A lasting commercial joint around New Town begins with the old bead fully out and the faces clean and dry.

Questions to ask before you book

  • Whether primer will be used where the manufacturer specifies it
  • The terms of the workmanship guarantee
  • The named product and why it was chosen
  • How joint depth will be controlled

Questions to ask before you appoint anyone

For managing agents and facilities managers

Blocks and communal areas make up much of the work for housing associations and agents. We phase the work so people keep access, with each stage agreed with your site contact.

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we’ll confirm them with the quote.

Honest limits

Some faults sit outside our scope, and we say so rather than covering them up:

  • Leaking roofs, gutters or flat-roof membranes (those need a roofer)
  • Misted, cracked or failed glazing units (a glazier’s job)
  • Suspect materials that need testing and specialist removal

Not sure which it is? You can ring 01277 525 020 or send details through our quote form and we’ll tell you honestly.

What we seal

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

What happens if it’s left?

Patching the worst lengths can be the right call on a tight budget. Where the remaining sealant is just as old, it tends to fail soon after, and a second visit means paying for access and set-up again. We can price both options so you can decide on the facts. Halls, stores and units around places like New Town may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a fixed quote and we will explain how it’s made up.
