Construction mastic for Higham sites

Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.

For managing agents and facilities managers

For main contractors, we work as the sealant subcontractor. We work to your programme, your specification and your site rules.

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. We can agree access arrangements and keyholder contacts beforehand.

Construction mastic in Higham

A typical mastic package covers more than window perimeters: frame perimeters inside and out, caulking to trims and boards where the specification calls for it, sanitary silicone, kitchens, and the final snag list. One contractor for all of it keeps the responsibility in one place, and one applicator team gives a consistent finish. If you are dealing with oversized or tapered gaps around new frames and internal caulk splitting as the building dries out, we can help. One point of contact handles commercial sealant work in Higham from the first photographs to the final walk-round, whether it’s one building or several.

Around smaller places like Higham, building work normally means conversions of farm buildings, a few new houses or an extension to a hall or school. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

How the quote is worked out

A fixed quote reflects the actual work. It takes account of:

  • Removal of failed or old sealant
  • Phasing around occupants
  • Which sealant the job calls for
  • The site’s rules and procedures

There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote.

Details that help us quote

Good information means a firmer quote. Helpful details to send:

  • Approximate linear metres or a joint schedule
  • Photos of the joints, close up and from further back
  • Access details, including height
  • What the building is and how it’s used

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, give us a call on 01277 525 020 or email a schedule or drawings.

Questions about Higham

Can you work around term dates at a campus such as University for the Creative Arts - Rochester?

Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.

Is a smaller place like Higham outside your area?

No. Small places get the same service as large ones. We cover Greater London and the counties of the South East. Good photographs up front let us bring everything on the first visit.

Do you offer coloured sealant?

It depends on the product. Some ranges are wide, others limited, so we will confirm the colours available for the specified product with the quote.

Do you do fire-rated sealing on new builds?

We install fire-rated sealant where it is the specified product, working to the specification and the manufacturer’s installation guidance. We will flag if the detail needs a different product.

Will you come and look before quoting?

Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit.

How long do sealant joints last?

There isn’t a single answer, since movement, weather, cleaning and use all affect it. Regular inspection is the best way to catch problems early.

What will the job cost?

We don’t publish prices, because every site is different. Send photos or drawings and we will price it at a fixed figure.

From enquiry to sign-off

At the end of each section, we remove the tape, clean down and inspect every joint, ready for your sign-off. If an area should be left alone while the sealant cures, we say how long and put signs out. If others near Higham need work, visits can be combined. You will have a fixed quote before work starts.

  1. Drawings, specification and programme come to us.
  2. We take off quantities and return a fixed quote.
  3. We agree with the site team which areas come first.
  4. Each area is sealed when it’s released.
  5. Joints are prepared, backed and sealed to the specification.
  6. Snags are cleared and the package signed off with our 12-month guarantee.

Preparing the site

Advice

How the job changes by surface

Fire-rated sealant where specified

Not every penetration suits a sealant. Other products are used for some services and gaps, and we will tell you if the detail calls for something else. 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. A single team keeps the standard consistent following the programme.

Facades, frames and programmes in Higham

Higham sits in one of the drier corners of the country, the South East. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so we time external mastic for dry faces and agree it with the site team. Central London is about 24 miles from Higham. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, which keeps mastic packages in demand.

Hospital estates such as French Hospital, 2.8 miles to the south-east of Higham, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan. When a school such as Higham Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. Recladding or extending a unit at a site like Nuralite Industrial Estate, 1.6 miles to the north of Higham, brings panel joints and frame perimeters into the programme.

Higham is about 2 miles north-west of Rochester, in Kent. We send applicators to Higham for mastic packages, handled exactly as we handle every other area. Higham is one of 931 places we cover in Kent. London is covered too, around 24 miles from Higham.

Business premises anywhere in ME3 and DA12 are within our area for mastic packages. Streets here include Villa Road, Darby Gardens and Ash Crescent. If your building is just outside Higham, we cover Gadshill (1 mile south), Lower Higham (1 mile north), Shorne (1 mile west), Shorne Ridgeway (1 mile south-west) and Mockbeggar (2 miles east). A short drive away, we cover Maidstone (11 miles south), Sittingbourne (13 miles south-east), Dartford (10 miles west), Sevenoaks (15 miles south-west), Gravesend (4 miles west) and Northfleet (5 miles west).

Looking after the joints

Regular inspection catches problems early. Specifically:

  • Check frame gaps are within the sealant’s range before sealing
  • Put any product change through the designer first
  • Share drawings and the specification as soon as possible
  • Plan external elevations with the weather in mind

A new structure shifts as it loses construction moisture. Flexible sealants in the right joints handle normal movement, but caulk in a joint that moves more than expected may crack. We can advise if a joint needs a different product.

One unsealed frame can let water into finished internal areas. That normally means redoing finishes in a completed area and possibly a delayed handover. A check of every frame before decorators start is worth the time.

General trades versus a specialist

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

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.
