About our mastic sealing in Kingsfold

Across Kingsfold and the rest of West Sussex, we work the same way: you send details, we return a fixed quote, the joints are resealed and the 12-month guarantee follows. A list of buildings, a few photos and approximate joint numbers are enough for a quick quote or we can visit. If you are dealing with draught complaints from residents or tenants and water getting in round frames after rain, we can put it right, whatever the surface. A specialist sealant contractor works differently from a general builder: in Kingsfold, that means joint design, primers and backing rod as standard.

Rural conversions near places like Kingsfold often set modern frames into older stone, flint or brick. Perimeter mastic there has to grip an uneven face and suit the building’s character.

Building owners and contractors get the same cover: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Questions we’re asked in Kingsfold

Do you cover business parks and estates near Kingsfold, such as Northlands Business Park?

Yes. Estates, retail parks and business parks around Kingsfold, Northlands Business Park among them, are all within reach. To start, just give us a call on 01277 525 020 or send photos by email with the unit, the joints involved and your access times.

Is Kingsfold too small for you to travel to?

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

Is asbestos a concern with old mastic?

We don’t remove asbestos-containing materials. If old sealant is suspected, work stops until it’s tested in line with the dutyholder’s asbestos management.

How long does a job like this take?

It depends on the scope, but the work normally takes one or more days per building, depending on the joint lengths and the access. For bigger or phased jobs, we’ll set out a timescale with the quote.

Do you take on small jobs?

We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.

Do you work to architects’ specifications?

Yes. The specification and the manufacturer’s installation guidance are what we work to.

Do you seal on top of existing sealant?

No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.

Looking after buildings in and around Kingsfold

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. At about 28 miles from central London, Kingsfold is within reach of the capital. Around the capital’s commuter belt, managing agents look after many blocks close to stations and town centres; their frame mastic often ages block-wide.

Property owners at sites such as Northlands Business Park, 1.7 miles to the west of Kingsfold, can have mastic renewed between lettings. Buildings close to stations like Warnham station (to the south of Kingsfold) are often flats over shops, with frame mastic to keep sound.

Kingsfold is about 3 miles north of Horsham, in West Sussex. Businesses, contractors and managing agents in Kingsfold can call on us for mastic joints. Kingsfold is one of 373 places we cover in West Sussex for mastic joints. There’s a separate page for Brighton, roughly 21 miles from Kingsfold.

We cover the RH12 postcode districts for mastic joints. If your site is on Foxwood, Priors Wood and Dorking Road or close by, send details and we’ll quote for mastic joints.

Further afield, our area takes in Crawley (6 miles east), Horsham (3 miles south), Haywards Heath (13 miles south-east), Burgess Hill (14 miles south-east), East Grinstead (14 miles east) and Broadfield (6 miles east).

Building owners, agents and FMs in Kingsfold

We take on planned maintenance as well as one-off repairs: resealing failed joints building by building, on a schedule that suits your budget. Sites in Kingsfold can sit alongside others in a wider programme.

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.

How the quote is worked out

The price varies from site to site. Expect it to depend on:

  • Phasing around occupants
  • Access and working height
  • Site requirements such as inductions and permits
  • How much existing material needs removing

A quote for mastic joints depends on quantities, condition and access. Ask us for a fixed quote.

What to include in your enquiry

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

  • Photos of the joints, close up and from further back
  • The product your specification calls for
  • The type of building and who uses it
  • Your programme or deadline

A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we will fill any gaps with a visit.

Why act early in Kingsfold

Adding sealant to cyclical maintenance is an easy win. Leaving it until there’s a leak turns it into reactive work and less choice about when. Older rural buildings around Kingsfold move with the seasons, and rigid or tired sealant can’t keep up. 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.

What you get with us

  • Workmanship guaranteed for 12 months
  • Coloured sealants to suit the setting, where available
  • CHAS accredited contractor
  • Work to your specification and the manufacturer’s guidance

How a job runs

We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. After that, any old or failed material is removed, each joint is prepared and the new sealant goes in. For a building around Kingsfold, tell us how to find it and who will meet us. Add it to your enquiry and we will build it into the plan.

  1. We inspect the joints, building by building, and record what has failed and why.
  2. You get a fixed quote, priced per building where that helps your budgeting.
  3. The programme is fixed with you, including dates you can pass on to residents or tenants.
  4. We remove the old mastic completely and clean the joint faces back.
  5. Backing rod and primer go in where the joint and the product need them, then new sealant is applied and tooled.
  6. Each building is checked on completion and the work carries our 12-month guarantee.

Preparing the site

  • Send asbestos survey details if the building is pre-2000
  • Arrange parking or a loading space
  • Let building users know which areas are affected

How the job changes by surface

Window and door perimeters on blocks

On most blocks, the frame-to-wall joint is where failure shows first. We remove the failed mastic, prepare the faces, add backing rod if the joint is deep and reseal.

Communal areas

We keep entrances and stairs open throughout. We work in sections so access is never blocked.

After the work

Regular inspection catches problems early. In particular:

  • Make mastic part of routine maintenance checks
  • Look at the sunniest and most exposed elevations first
  • Encourage occupiers to report problems at frames
  • Keep a record of when each building was resealed

Where a paintable product was specified, it can be painted after curing. Non-paintable silicone shouldn’t be painted over.

Water getting in round frames can damage plaster, decoration and the frames themselves. Early resealing is far simpler than repairs inside.
