Construction mastic near Lenham Heath

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

For managing agents and facilities managers

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Lenham Heath can sit alongside others in a wider programme.

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, so there’s one set of paperwork to deal with.

Construction mastic in Lenham Heath

Getting a subcontractor through site induction should be simple. Our applicators are CSCS-carded, and we’re CHAS accredited and a Constructionline member, and we’re fully insured. Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We work on window and door perimeters, brick and block movement joints and internal decorators’ caulk, and the usual reasons a site gets in touch are snag items on joints that need redoing before handover and failed sealant in an existing building being refurbished. Facilities teams, main contractors and managing agents in Lenham Heath tend to want the same three things: a clear scope, tidy work and joints that don’t fail again.

In the countryside around places like Lenham Heath, conversion schemes put new frames into old stone, flint, brick or timber. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Sites and facades in and around Lenham Heath

Lenham Heath has several hotels close by, all within 2 miles. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up. Central London is about 41 miles from Lenham Heath. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and each scheme needs its mastic sealed to programme.

For a contractor at a hotel such as Chilston Park Hotel, 1.4 miles to the west of Lenham Heath, the mastic often has to be finished before a reopening date. When a school such as The Lenham School is extended or refurbished, the mastic package is often squeezed into the holidays.

What sealant work can’t fix

A few problems need another trade or a different fix, and we point that out rather than sealing over them:

  • Glazing units that are cracked or misted
  • Rework caused by others damaging completed areas
  • Joint design decisions that belong to the architect or engineer

If in doubt, ring 01277 525 020 or email us and we’ll say what we think.

Where we work in Lenham Heath

  • Window and door perimeters
  • Internal decorators’ caulk
  • Cladding and panel joints
  • Sanitary and kitchen joints
  • Floor and skirting junctions
  • Brick and block movement joints

Doing it in-house

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

General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint, which is what makes a joint last.

Common questions from Lenham Heath clients

Can you keep pace with our programme in Lenham Heath?

Yes, we work to the programme and the sequence the site sets. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Can work at a site such as Canterbury Christ Church University fit around teaching?

Yes, holiday working periods are the norm on campus jobs. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Can you fit around our working hours?

We’re in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.

Do you use the sealant named in the specification?

The specification decides the product. Specifications often reference BS EN 15651 or BS 6213.

Does the weather affect the work?

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.

How long will the new sealant last?

Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.

Do your applicators hold CSCS cards?

We’re CHAS accredited and a Constructionline member, and our applicators hold CSCS cards. Tell us what site paperwork you need and we will confirm with the quote.

Cost factors for mastic packages

What shapes the price:

  • Backing rod, priming and other preparation
  • How much existing material needs removing
  • Which sealant the job calls for
  • Access and working height

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

Before you send an enquiry

A good diagnosis starts with the right details. Let us know:

  • Access details, including height
  • The product your specification calls for
  • Whether an asbestos survey exists
  • Photos of the joints, close up and from further back

Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. To get it moving, give us a call on 01277 525 020 or email us.

Do you need construction mastic in Lenham Heath?

On construction sites, joints normally fail early because of when they were sealed, not what was used. Sealing before decorators, flooring or other trades have finished leaves joints exposed to damage.

Most enquiries start with one or more of the following:

  • Bath and shower joints scraped during the final clean
  • Existing joints on a refurb that need cutting out and resealing
  • Early adhesion failures on new external joints
  • Missed perimeter joints on a new elevation

University estates such as Canterbury Christ Church University (to the north-west of Lenham Heath) tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal.

Comparing quotes

  • How joint depth will be controlled
  • What level of public liability insurance do they hold?
  • The terms of the workmanship guarantee
  • How the existing material will be dealt with

How to choose a sealant contractor

Diagnose, treat, sign off

On arrival, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself typically taking a day or two on a small fit-out and several weeks on a large multi-storey package. Smaller jobs around Lenham Heath can be grouped with others nearby. You will have a fixed quote before work starts.

  1. Drawings, the sealant specification and your programme come to us for pricing.
  2. A fixed quote sets out the scope, the products and the sequence.
  3. Any site paperwork you need (RAMS, insurance certificate, CSCS details) is confirmed with the quote.
  4. Work follows the programme, area by area, as rooms and elevations become ready.
  5. Each joint is prepared, backed to depth and sealed in the product the specification names.
  6. Before handover, snags are dealt with and the package is signed off under our 12-month guarantee.

Before we start on site

  • Arrange parking or a loading space
  • Clear stock, furniture or equipment away from the joints
  • Share the asbestos register for older buildings

Request a quote

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