Questions about Chalkhouse Green

Can the sealant on our Chalkhouse Green premises match the finishes?

Yes, sealants come in a wide range of standard colours, and matching to RAL references, cladding, stone or frames is a common request. Available colours for the product are confirmed with the quote.

Is a smaller place like Chalkhouse Green outside your area?

No. Small places get the same service as large ones. London and every South East county are within our area. Send photos and a list of what needs doing, and we’ll plan the job to need as few trips as possible.

Do you check for asbestos before removing sealant?

In buildings from before 2000 in particular, some old mastics and sealants may contain asbestos. Before cutting anything out, we ask for the asbestos register or survey, and if something is suspected, work stops until it’s tested.

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

No. Overlaying old sealant is a frequent cause of early failure, so everything comes out first.

How is commercial sealant work priced?

Send photos, drawings or a list of locations through our quote form. Where we need to see it, we’ll arrange a site visit, then send a fixed quote.

Do you work for facilities managers and managing agents?

Yes. FMs, managing agents and landlords are among our regular clients as well as contractors. Tell us how you issue work and we will fit in.

Does the weather affect the work?

Outside, yes. Sealant needs a dry joint and a temperature within the product’s range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.

Sealant specialists in Chalkhouse Green

Having a single contact for all your sites makes sealant far simpler to manage. Single jobs, multi-site packages and planned programmes all come to us: send details, get a fixed quote, we seal, and a 12-month guarantee once it’s signed off. To get a programme moving in Chalkhouse Green, speak to us on 01277 525 020 or email the details over with the site addresses. We work on kitchen worktops and splashbacks, window and door perimeters and movement joints in walls and floors, and the failures we’re asked to look at most are a top-up bead over failed sealant, now lifting and external beads that have gone brittle and cracked. A specialist sealant contractor works differently from a general builder: in Chalkhouse Green, that means joint design, primers and backing rod as standard.

In Chalkhouse Green, as anywhere, the first joints to go are typically the ones that work hardest: frame perimeters in the sun, floor joints at doorways and anything that gets wet every day.

Commercial sealant work around smaller places like Chalkhouse Green tends to mean pubs and restaurants, halls, farm shops and offices in converted farm buildings. Kitchens, toilets and window frames in all of them need resealing sooner or later.

Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

Work for main contractors and building owners

Whether you are a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We’re fully insured, and our insurance certificate can go with the quote.

How the quote is worked out

Each job is priced on its own details. The main factors are:

  • How accessible the joints are
  • How much existing material needs removing
  • Working within restricted access windows
  • Quantities, in metres or numbers

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

Before you send an enquiry

We can often quote from photographs and a few details. It helps to include:

  • The site address and postcode
  • Clear photographs of the problem areas
  • How the joints are reached, and at what height
  • The type of building and who uses it

Tell us about the building, the joints and when you need the work done, and we’ll put a fixed quote together. To get it moving, call the office on 01277 525 020 or send photos by email.

From enquiry to sign-off

Working in a building that stays open takes some planning. We sign and contain the area we’re in, with routes through the building left open and work section by section so the rest of the building stays in use. Smaller jobs around Chalkhouse Green can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.

  1. We start with the evidence: photographs, drawings or a look on site.
  2. You get a fixed quote covering removal, preparation and the new sealant.
  3. We agree the order of work, access windows and site hours with you.
  4. Each joint is stripped, cleaned back to sound faces and primed where the maker specifies.
  5. Depth is set with backing, then the sealant is applied, tooled and the area tidied.
  6. We hand back each area with its cure time and our 12-month guarantee.

What we need from you

  • Share your working hours and any access restrictions
  • Warn occupants and staff about the work
  • Clear stock, furniture or equipment away from the joints

Getting a fixed quote

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. For smaller jobs, photographs and a description will do.

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:

  • A dripping trap, valve or pipe behind a fitting
  • Structural cracks or movement the joints weren’t designed for
  • Faulty windows rather than failed perimeter sealant

Not sure which it is? You can call the office on 01277 525 020 or email the details over and we’ll tell you honestly.

Surfaces we seal

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

Maintenance after handover

A few simple habits keep the new joints working:

  • Note dates and locations of sealant work for future planning
  • Add sealant to the planned maintenance inspection list
  • Deal with small splits before they become leaks
  • On pre-2000 buildings, share the asbestos information before work starts

Our workmanship on each job is backed by a 12-month guarantee. Keep the handover details with your O&M or maintenance records so it’s easy to find if a joint we sealed gives trouble inside the 12 months.

Movement joints that fill with debris stop working. The joint can no longer close, so its edges crack or spall. That turns a sealant job into something bigger.

Do you need commercial sealant contractors in Chalkhouse Green?

If sealant tears through its centre, it has failed cohesively. That usually means the joint stretched further than the product could cope with because the bead was too thin, the joint over-stretched or the movement class wrong. Replacing it like for like rarely holds.

What tends to prompt an enquiry:

  • Frame mastic that has hardened and come away from the wall
  • A top-up bead over failed sealant, now lifting
  • Damp patches where an external joint has failed
  • Untidy joints in a reception, shop floor or lobby

For premises near Reading station, 2.6 miles to the south of Chalkhouse Green, footfall is part of the plan: work is phased so shops and offices keep trading.

What your quote should include

  • Will RAMS and insurance details be available?
  • Will CSCS-carded applicators be on site?
  • How long is the guarantee, and what does it include?
  • Health and safety accreditation such as CHAS

Choosing a commercial sealant contractor

Frontages, fit-outs and joints in Chalkhouse Green

Tenant changes on such sites bring fit-outs, and fit-outs bring new joints, often in a colour the occupier specifies.
