Mastic sealing in Boxley

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

Building owners, agents and FMs in Boxley

Facilities managers want contractors who arrive with the paperwork sorted. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

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.

About our mastic sealing in Boxley

For over 20 years we have resealed joints for owners, agents and landlords. Our applicators are CSCS-carded, and the work is backed by public liability insurance. Each building we complete carries a 12-month guarantee on our workmanship. We work on shopfronts below residential blocks, communal entrances and stairwells and external wall and movement joints, and the usual reasons a site gets in touch are estate-wide sealant that is simply worn out and a mix of products and colours from past repairs. One point of contact handles commercial sealant work in Boxley from the first photos to the final walk-round, for single jobs and planned programmes alike.

Owners and agents with buildings around smaller places such as Boxley tend to manage small terraces of association properties, converted barns and commercial units. Mastic around frames and on external joints wears out in time, whatever the building.

Our 12-month guarantee is about workmanship, not wear and tear. Sealant wears with time, and movement, weather, cleaning and use decide how fast, so we spell out the cover before we begin.

Diagnose, treat, sign off

Site rules come first: signing in, inductions and any permit to work. With the paperwork done, the joints are worked through in the order agreed with your site contact, and each area is checked before we leave it. Rural sites near Boxley may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

  1. First we look at the mastic on each building and note what needs replacing.
  2. A fixed quote follows, split by block or building if that suits you.
  3. Dates, areas and access are agreed so residents or tenants can be told in advance.
  4. We remove the old mastic completely and clean the joint faces back.
  5. Deep joints get backing rod, faces are primed if the manufacturer specifies it, then the joint is sealed and tooled.
  6. Each building is checked on completion and the work carries our 12-month guarantee.

Before we start on site

  • Send asbestos survey details if the building is pre-2000
  • Arrange parking or a loading space
  • Share your working hours and any access restrictions

Related advice

Site staff or a sealant specialist?

Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Some joints are best left to specialists: fire-rated seals that must follow a tested detail, trafficked floor joints and external movement joints among them. Getting these wrong usually costs more in the end than doing them right.

When to call us in Boxley

Communal entrances and corridors see a lot of wear, and low-level joints get damaged. Regular cleaning wears them further.

It’s worth sending us details if you spot any of the following:

  • Failed external movement joints
  • A mix of products and colours from past repairs
  • Water getting in round frames after rain
  • Cracked, hardened mastic round windows on a block

Site managers at schools like Sandling Primary School can fit frame mastic into the summer works.

Questions to ask before you book

  • Will failed sealant be removed rather than covered?
  • How they’ll work around occupants
  • Will RAMS and insurance details be available?
  • How joint depth will be controlled

Questions to ask before you appoint anyone

Planned mastic for Boxley portfolios

Boxley is about 31 miles from central London. Within reach of London, blocks run by agents and associations are common around stations. The South East is one of the drier parts of the UK. External mastic still waits for dry faces and the right temperature, and elevations facing the sun and the prevailing weather are normally where frame mastic ages first.

If you look after a block within reach of Maidstone East station, 2.2 miles to the south-west of Boxley, frame and balcony mastic can be renewed on one programme. For owners of several units at places like Viewpoint Industrial Estate (1.1 miles south of Boxley), one programme can deal with frame and external mastic across the lot.

Boxley is about 3 miles north of Maidstone, in Kent. Any commercial site in Boxley is covered, whether it’s a single job or part of a planned programme. We work across 931 places in Kent, large and small. London is covered too, some 31 miles away.

If you need mastic sealing in ME14, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee.

Leave it or put it right?

Dealing with failed joints one report at a time is slow and scattered. Planned resealing covers a whole building or estate in one go and is simpler to manage and budget. Converted and older buildings near places like Boxley tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

Access can matter as much as the joints themselves: joints within easy reach take less time than ones that need access equipment. Tell us how the joints are reached and call for a quote.

Questions we are asked in Boxley

Does your area include sites such as Viewpoint Industrial Estate, near Boxley?

Yes. We cover Boxley and the area around it, including industrial estates, business parks and retail parks such as Viewpoint Industrial Estate. Send details of the unit and the work through our quote form for a quick quote.

We manage a building near Maidstone East station. Can you help?

Yes, we work for agents, landlords and housing associations with blocks of every size. Photos of each elevation help us quote accurately.

Do you do block-wide mastic programmes?

Block-wide and estate programmes are common. The quote can be split however suits your budgeting.

When can the area be used after sealing?

That comes down to the sealant and the temperature. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

Is asbestos a concern with old mastic?

Some mastics in pre-2000 buildings contain asbestos. We check the asbestos register or survey before disturbing it and suspect material is tested first.

Can you seal joints high up on a block?

Access is discussed and agreed before the quote is fixed. Tell us the number of storeys and whether scaffold or other access is planned and we will confirm the approach in the quote.
