Advice

How we handle construction mastic in South Alkham

The programme rarely stands still, so the mastic package has to flex with it. The sequence is set with the site team and updated as plots or floors are handed over. Sealing too early only means coming back once others have damaged it. If you’re dealing with snag items on joints that need redoing before handover and failed sealant in an existing building being refurbished, we can put it right, whatever the surface. A specialist sealant contractor works differently from a general builder: in South Alkham, that means joint design, primers and backing rod as standard.

Conversions of older rural buildings near smaller places such as South Alkham bring stone, flint, brick and timber up against new glazing. Those joints need a sealant that suits an uneven, sometimes porous surface, and often a colour chosen for the building.

Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and the quote explains what it covers.

For managing agents and facilities managers

As a CHAS accredited contractor and Constructionline member, we’re straightforward to vet for your supplier list. Our insurance certificate can be sent along with the quote.

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

What the job involves on each 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.

Bathrooms, en suites and washrooms

Across a block of flats or a hotel, sanitary sealing is repeated in every room. One applicator team gives the same finish everywhere, plot by plot or floor by floor.

What affects the price in South Alkham

Sealant work doesn’t have a standard rate, since sites vary so much. What we take into account:

  • Working within restricted access windows
  • Whether old sealant has to be cut out first
  • Backing rod, priming and other preparation
  • Site requirements such as inductions and permits

Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.

Before you send an enquiry

A good diagnosis starts with the right details. Tell us:

  • Specification clauses that apply
  • Any dates the work must fit around
  • Whether the building will be occupied during the work
  • A wide shot and a close-up of the area

To get a fixed quote, give us a call on 01277 525 020 or email a schedule or drawings, telling us the site location and the nature of the job. You can also send details through our quote form.

Facades, frames and programmes in South Alkham

The sea is no more than about 2 miles from South Alkham. Facades and window perimeters on coastal schemes take more wind-driven rain, and salt air nearer the shore, and the sealant, primer and backing need choosing with that in mind. At about 62 miles from central London, South Alkham is within reach of the capital. Towns within reach of London tend to keep building, from flats to offices and schools, and each scheme needs its mastic sealed to programme.

On a healthcare site such as Buckland Hospital (3.4 miles east of South Alkham), new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully. For contractors on a campus like University Centre Folkestone, which lies south of South Alkham, facade and perimeter sealing has to fit around students and term dates.

Doing it in-house

For a quick touch-up, site staff may be fine, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Questions we’re asked in South Alkham

Will you plan work around the academic year at somewhere like University Centre Folkestone?

Yes, holiday working periods are the norm on campus jobs. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Is South Alkham too far out for you?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Can you work while the building is occupied?

In the majority of cases, yes. Phased work can be planned so areas stay in use, with each area protected and signed.

How do I request a quote?

There are four steps: send details, get a quote, we seal, guaranteed. The first step only needs photographs and a postcode.

Can you seal external joints in wet or cold weather?

Conditions have to suit the product before external work starts. Sealing in poor conditions risks adhesion failure, so we wait rather than redo work.

Are you insured?

Yes. Our insurance certificate can be sent alongside the quote.

Can you work to our specification?

We follow the specified sealant and flag anything that doesn’t look right for the joint. Product standards such as BS EN 15651 are often named in specifications.

Do you need construction mastic in South Alkham?

On construction sites, joints typically 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.

Common reasons buildings call us in:

  • Window and door perimeters that won’t pass inspection
  • Existing joints on a refurb that need cutting out and resealing
  • Early adhesion failures on new external joints
  • A mastic package split between trades with no clear owner

Older buildings in the area around South Alkham, such as Acrise Place, 3.5 miles west of South Alkham, need care when sealed: the product has to suit soft or historic materials.

What to look for in a quote

  • Are they CHAS accredited or on Constructionline?
  • Will failed sealant be removed rather than covered?
  • Whether primer will be used where the manufacturer specifies it
  • Their approach to joint depth and backing
