Construction mastic for commercial buildings in Newland Green

A typical mastic package covers more than window perimeters: external door and window perimeters, internal decorators’ caulk where specified, sanitary joints in bathrooms and washrooms, kitchen worktops and splashbacks, and snagging before handover. Splitting those between trades often leaves gaps in responsibility and gives you a consistent finish across the job. We work on floor and skirting junctions, internal decorators’ caulk and sanitary and kitchen joints, and the failures we are asked to look at most are cracks opening in caulked internal joints and early adhesion failures on new external joints. A single leaking joint is often how a building in Newland Green first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.

Sites around smaller places like Newland Green can be a fair drive from suppliers, so we come with everything the package needs. Send drawings or photos and the programme and we will quote to suit.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

Leave it or put it right?

When a package runs over budget, downgrading the product is a common first thought. The saving is small next to the cost of callbacks and defects and external joints are where it shows first. We price the specified product and will tell you plainly where an alternative would or wouldn’t work. Converted and older buildings near places like Newland Green tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.

We don’t publish prices, because the scope varies so much from one building to the next. Call for a quote and we will price your job on its own details.

Why appoint us

  • Products installed to the manufacturer’s instructions
  • Failed material removed, not covered up
  • Sealing commercial buildings since 2005
  • Colours confirmed for the specified product

Common questions from Newland Green clients

Will you fit the mastic around our build programme in Newland Green?

Yes. The mastic is planned around your key stages. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Which documents can you supply for work in Newland Green?

We will confirm the paperwork you need, such as RAMS, our insurance certificate and CSCS details, with the quote. Our applicators are CSCS-carded, and we carry £5m public liability insurance.

Do you use the sealant named in the specification?

The specification decides the product, and we will raise it if something in it doesn’t suit the joint. Specifications often reference BS EN 15651 or BS 6213.

How many days will you need on site?

We plan the time on site around your programme and access. We will give you an estimate of time on site when we quote.

Do you work to architects’ specifications?

Yes. We follow the specification, along with the manufacturer’s installation guidance, and we raise anything unclear before work begins.

Can you quote from photos?

It depends on the job. Simple work can often be priced from photos, and bigger or more complex jobs typically get a visit.

Do you have public liability insurance?

Yes. We are fully insured, and the certificate can go with your quote.

Construction mastic around Newland Green: how the place shapes the job

Newland Green is about 41 miles from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, so mastic packages have to keep pace with busy programmes. The South East is one of the drier parts of the UK. That doesn’t stop wet spells, or frosty starts that leave panels too damp to seal, so external mastic is timed for workable conditions and agreed with the site manager.

School extensions, at buildings such as Egerton Church of England Primary School, usually run to the summer holidays, mastic included.

Newland Green is about 7 miles north-west of Ashford, in Kent. Across the TN27 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Across Kent, 931 places are covered, including Newland Green. Our London page has more on work in that area.

How the quote is worked out

Your fixed quote is built from the real scope. It allows for:

  • How much existing material needs removing
  • The site’s rules and procedures
  • Quantities, in metres or numbers
  • Whether the work must be split into stages

Pricing mastic packages depends on how many there are, their condition and the access. Ask us for a fixed quote.

Sending details for a quote

A few photos plus some basic facts will normally do. It helps to include:

  • Whether an asbestos survey exists
  • Clear photographs of the problem areas
  • Drawings or a marked-up plan, if available
  • Where the site is, with the postcode

Tell us about the building, the joints and when you need the work done, and we will put a fixed quote together. The easiest way is to give us a call on 01277 525 020 or email drawings and photos.

How the job changes by surface

Fire-rated sealant where specified

Fire-rated sealant is one type of fire-stopping product. Other products are used for some services and gaps. Tell us what records you need and we’ll confirm with the quote.

Internal decorators’ caulk

Where the specification calls for it, acrylic decorators’ caulk goes on non-moving internal gaps before painting. It’s for gaps that stay still and get painted, and we use a flexible sealant where there’s movement.

Common problems we fix in Newland Green

A new building moves while it dries and settles. Plaster, screeds, timber and blockwork all shrink as they lose moisture. Picking a flexible sealant where there’s movement keeps snags down.

What tends to prompt an enquiry:

  • New external sealant already peeling away
  • Existing joints on a refurb that need cutting out and resealing
  • A mastic package split between trades with no clear owner
  • Snag items on joints that need redoing before handover

Sites around Newland Green get mastic sealed to the drawings and the programme, nothing improvised.

How to choose a sealant contractor

You will have a fixed quote before work starts.

Advice

What sealant work can’t fix

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

  • Frame gaps too wide for sealant, which the installer needs to correct
  • Designing joint widths or choosing the specification (that sits with the designer)
  • Faulty frames rather than failed sealant

If in doubt, give us a call on 01277 525 020 or use the quote form and we will say what we think before you book.

Surfaces we seal

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