About our mastic sealing in Horsmonden

In buildings from before 2000, some old mastics contain asbestos. We check the asbestos register or survey before any old sealant is cut out, and work stops for testing if there’s any doubt. Removing asbestos-containing material isn’t something we do. We work on balcony and threshold joints, shopfronts below residential blocks and window and door perimeters on blocks, and what we are called in for most is estate-wide sealant that is simply worn out and no planned programme for sealant. Most enquiries from Horsmonden start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.

For owners with a single building near Horsmonden, we plan to finish in one visit where possible. Send photographs of the frames and joints and we will give a fixed quote.

We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and we come back if anything isn’t right.

Block-wide mastic in Horsmonden

Horsmonden lies roughly 34 miles out from central London. Within reach of London, blocks run by agents and associations are common around stations. Horsmonden is in the South East, one of the UK’s drier regions. Even so, frame mastic only goes on in dry, workable conditions, while the elevations that take the most sun tend to show hardened mastic first.

Site managers at schools like Horsmonden Primary School can fit frame mastic into the summer works. If you look after a block within reach of Paddock Wood station, which lies north-west of Horsmonden, frame and balcony mastic can be renewed on one programme.

Horsmonden is about 7 miles east of Royal Tunbridge Wells, in Kent. Any commercial site in Horsmonden is covered, for single jobs and planned programmes alike. 931 places across Kent fall within our area, including Horsmonden. Brighton is covered too, some 32 miles away.

What sealant work can’t fix

Our job is the joint, not everything around it. On its own, sealant can’t deal with:

  • Substrate edges that need repairing first
  • Failed window or door frames, which need a window contractor
  • Materials that need asbestos testing before work

Not sure which it is? You can call the office on 01277 525 020 or use the quote form and we will tell you honestly.

Joints and surfaces we work on

  • Balcony and threshold joints
  • Window and door perimeters on blocks
  • External wall and movement joints
  • Communal entrances and stairwells
  • Communal kitchens and washrooms
  • Shopfronts below residential blocks

How a job runs

In a busy building, the work is phased so only one area is out of use at a time. Each section is protected, cleaned back and sealed before we move to the next. Rural sites near Horsmonden may need directions, gate codes or a contact on site. Add it to your enquiry and we will build it into the plan.

  1. We check the asbestos register for older buildings and look at the joints.
  2. A fixed quote covers the joints, products and order of work.
  3. Failed mastic is removed completely.
  4. The joints are prepared and resealed with the right product.
  5. We finish each building before moving to the next.

Getting the site ready

  • Make sure the joints can be reached
  • Confirm the product named in the specification

Questions about Horsmonden

Do you take on block-wide or estate-wide mastic work in Horsmonden?

Yes. Portfolio-wide programmes are a regular request. We can phase the programme to suit your budgets and notice periods.

Is Horsmonden off your patch?

No. Places such as Horsmonden are covered as much as the big towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.

How long before the joints can be used?

We’ll confirm how long the chosen product needs to cure, and flag anything to keep off until it has cured.

How many days will you need on site?

The duration is planned around your programme and the access we are given. You will have an expected duration with the quote.

When is resealing likely to be due?

There isn’t a single answer, 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.

What guarantee do you give on resealing?

A 12-month guarantee covers our work. It covers our workmanship, not later building movement, damage or frame failures.

Can you take on resealing for a block portfolio?

We do. Managing agents, property factors in Scotland, housing associations and landlords with block or commercial portfolios are our main clients for this work, and we quote building by building or as a programme.

Owners, agents and contractors

FMs need a contractor who is easy to get on site. Let us know the documents you need (RAMS, insurance certificate, CSCS details) and we will confirm them with the quote.

For main contractors, we work as the sealant subcontractor. Programme, specification and site rules come first, and our applicators hold CSCS cards.

Signs you need mastic sealing in Horsmonden

Previous repairs often sealed new mastic over old. New sealant won’t grip failed sealant and the repair soon fails.

Typical triggers for a call:

  • No planned programme for sealant
  • Brittle perimeter mastic across a building
  • A mix of products and colours from past repairs
  • Draught complaints from residents or tenants

Older buildings near Horsmonden, from historic houses such as Scotney Castle, 3.4 miles to the south of Horsmonden, to more modest stock, need compatible products when frames are resealed.

Questions to ask before you appoint anyone

Quoting for work in Horsmonden

Each job is priced on its own details. The things that drive the figure:

  • Distance, for remote addresses
  • Quantities, in metres or numbers
  • Any access equipment needed
  • Which sealant the job calls for

Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you will have a fixed figure to work with.

Details that help us quote

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

  • Your programme or deadline
  • What the building is and how it’s used
  • The postcode of the building
  • Rough lengths or quantities, or drawings if you have them

Send us photos, drawings or a joint schedule and a fixed quote comes back to you. Where a site visit makes more sense, we’ll arrange one.

Why it’s worth doing now in Horsmonden

Piecemeal repairs over the years often leave mismatched sealant. Resealing a whole building gives a consistent finish. One visit to deal with every failing joint makes more sense than several trips to a place like Horsmonden. Send photos of each area and we’ll quote for the lot.

What a job costs comes down to how many linear metres there are, what has to come out first and how the joints are reached. Call for a fixed quote once you have the details.

  • Workmanship guaranteed for 12 months
