Your questions answered

Is Lower Cadsden off your patch?

No. Places such as Lower Cadsden are covered as much as the big towns. We cover Greater London and the counties of the South East. Where we can, we group nearby jobs to make the most of each trip.

Can you work on a hospital site such as The Paddocks Hospital?

Yes. Healthcare sites are among the places we work. We follow the site’s permits, sign-in and infection-control procedures in every area.

Are you fully insured?

Yes. We are fully insured, including public liability cover.

Do you take on mastic snagging only?

Yes, we can. Share the list and photographs, and a fixed quote follows, with the work timed to your handover date.

How many days will you need on site?

The duration is planned around your programme and the access we’re given. We will give you an estimate of time on site when we quote.

What happens if the weather stops external sealing?

External sealant needs a dry joint and a temperature within the product’s range. Damp, frost or condensation on frames can stop work.

What joints do you seal on a new build?

External and internal frame perimeters, caulking where it’s specified, sanitary silicone, kitchen joints and snagging before handover. The scope follows your specification.

Construction mastic for commercial buildings in Lower Cadsden

Buyers, tenants and clients notice sealant lines long before they notice the structure. A smeared bead round a window or a gap behind a worktop ends up on the snag list. Our aim is joints that pass at the first inspection, area by area through the programme. We work on brick and block movement joints, internal decorators’ caulk and sanitary and kitchen joints, and the failures we are asked to look at most are a long mastic snag list close to completion and missed perimeter joints on a new elevation. Facilities teams, main contractors and managing agents in Lower Cadsden tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.

Around smaller places like Lower Cadsden, building work normally means conversions of farm buildings, a few new houses or an extension to a hall or school. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.

Every job ends the same way: guaranteed. You get a 12-month guarantee on our workmanship, and we explain exactly what that covers when we quote.

Why deal with it now?

A cheaper sealant can look like an easy saving on a large package. The saving is small next to the cost of callbacks and defects. Where an alternative is genuinely suitable, we will say so. Older rural buildings around Lower Cadsden move with the seasons, and rigid or tired sealant can’t keep up. A sealant with the right movement capability, correctly sized, lasts far better.

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Why clients in Lower Cadsden choose us

  • 12 months’ guarantee on every job
  • Colours confirmed for the specified product
  • Products installed to the manufacturer’s instructions
  • Joints cleaned back to sound surfaces

Do you need construction mastic in Lower Cadsden?

Swapping the specified sealant for a cheaper general-purpose product is a common cause of failure. A sealant that isn’t right for the substrate or the movement will fail ahead of time. We stick to the specified product, or put any alternative to you first.

Most enquiries start with one or more of the following:

  • Old sealant on a refurbishment that needs stripping before new work
  • Oversized or tapered gaps around new frames
  • Frame perimeters left unsealed or poorly sealed
  • Early adhesion failures on new external joints

New wings at hospitals like The Paddocks Hospital (to the south-west of Lower Cadsden) bring long runs of window and panel joints to seal.

Before you book anyone

  • What site paperwork they can supply
  • Are they CHAS accredited or on Constructionline?
  • Will failed sealant be removed rather than covered?
  • Can the work be phased to keep areas open?

Surface by surface

Kitchens and utility areas

Commercial kitchens often need hygienic or food-safe sealants. We follow the specification and seal to a smooth, cleanable finish.

External facade and movement joints

Many facade substrates need a primer before sealing. Primer goes on where the sealant maker calls for it and work only when conditions suit.

For managing agents and facilities managers

Building owners and managing agents use us on everything from one building to a spread of sites. One quote can cover more than one site, which keeps the paperwork simple.

Agents, factors and owners’ representatives all follow the same route: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

Cost factors for mastic packages

There’s no standard rate for sealant work, because every site is different. What we look at:

  • The site’s rules and procedures
  • Whether old sealant has to be cut out first
  • Joint width, depth and condition
  • Working within restricted access windows

Quantities, awkward access and phased working all shape the price. So do site requirements such as inductions and permits, along with the time of year for external work.

Details that help us quote

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

  • Whether the building will be occupied during the work
  • How the joints are reached, and at what height
  • Clear photographs of the problem areas
  • Any specification or named product

If there’s a specification, drawings or a tender package, send it with your enquiry, and we’ll price the work to it. Smaller jobs need nothing more than photographs and a few notes.
