Your questions answered

Can you work at a site such as Parsonage Farm Business Centre, by Birchett's Green?

Yes. Our area takes in Birchett's Green and its surroundings, with estates and business parks such as Parsonage Farm Business Centre included. To start, just phone 01277 525 020 or email us with the unit, the joints involved and your access times.

Is hospital work, at somewhere like Ticehurst House Hospital, something you do?

Yes. Healthcare sites are among the places we work. The estates team’s permit system and infection-control rules come first, and the work is planned around them.

Do you take on multi-site work?

Yes. Several buildings can share a single quote, with one point of contact across South East England, Greater London and Scotland.

When is resealing likely to be due?

Nobody can honestly give a figure in years, 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.

Do you offer coloured sealant?

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

When can you be on site?

We’re in the office from 8am until 5pm, Monday to Friday. Let us know your site hours and access windows, and the work will be planned around them.

Is any job too small?

Small jobs are welcome alongside larger packages. Send details for a fixed quote.

Expansion joint sealing in Birchett's Green, done properly

We have been sealing expansion and movement joints for over 20 years. CHAS accredited, Constructionline member, CSCS-carded applicators and five million pounds of public liability insurance. Each job is backed by a 12-month guarantee on the workmanship. Most enquiries involve weathered movement joint sealant that no longer flexes and car park joints leaking onto vehicles below, on cladding panel joints, blockwork control joints and podiums and floor movement joints. Most enquiries from Birchett's Green start with one failed joint and grow into a wider look at the building: we look at the rest while we are there and tell you what we find.

In and around smaller places like Birchett's Green, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Joints in those slabs take vehicles, trolleys and foot traffic, and need a filler or sealant to match.

Our workmanship is guaranteed for 12 months. If our installation lets you down in that time, we return and fix it.

From enquiry to sign-off

Diagnose, treat, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then the work is carried out to the specified product and detail, and the job ends with a walk round and sign-off. Smaller jobs around Birchett's Green can be grouped with others nearby. A fixed quote is given before anything starts.

  1. We start with photos, approximate lengths and any drawings, visiting where needed.
  2. Joint widths and expected movement are checked against what the sealant can take, and flag anything that needs an engineer.
  3. Every joint is cleared of the failed seal and any grit packed into it.
  4. Any broken arrises or friable edges are flagged before work goes further.
  5. The right sealant goes in at the right depth, bonded to the two sides only.
  6. Areas reopen once cured, and the work carries our 12-month guarantee.

Getting the site ready

  • Point out parking and an unloading spot
  • Tell staff and tenants when we’ll be in
  • Share the asbestos register for older buildings

How the job changes by surface

Car park decks and ramps

Water coming through deck joints is the usual first sign. We strip the old seal, prepare the edges and seal again.

Concrete and precast panel joints

Precast panels often have surface residues that sealant won’t bond to. Proper cleaning and primer where specified give a sound bond and check the edges for soundness as we go.

Should maintenance staff do it?

Putting right a botched joint often costs more than sealing it well at the start, because the whole bead must be removed and the faces cleaned back again. That’s why many clients bring in a specialist from the beginning.

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.

What we’re called out for in Birchett's Green

With no backing rod or bond-breaker in place, sealant grips the base of the joint too. Sealant fixed to the base and sides can’t flex, so it tears.

Common reasons buildings call us in:

  • Torn sealant in brick or block movement joints
  • Weathered movement joint sealant that no longer flexes
  • Spalled or broken joint edges in floors and decks
  • Sealant pulling off the joint face

Office parks like Parsonage Farm Business Centre (1.8 miles south-east of Birchett's Green) have decks, ramps and clad elevations whose joints take movement every day.

Choosing a commercial sealant contractor

Floors, slabs and movement joints in Birchett's Green

At about 37 miles from central London, Birchett's Green is within reach of the capital. Distribution warehouses and industrial estates are common around the motorway corridors that serve the capital; their floors carry heavy traffic every shift. Rainfall across the South East, Birchett's Green included, is lower than in many parts of the UK. Even so, yard and car park joints are only sealed when they’re dry and clean, and gritting in cold spells finds its way into open joints.

Schools such as Uplands Community College have movement joints in their walls and floors that are easy to overlook. At places like Durgates Industrial Estate, 2.1 miles west of Birchett's Green, joints are sealed a section at a time so operations carry on.

Birchett's Green is about 7 miles south-east of Royal Tunbridge Wells, in East Sussex. Any commercial site in Birchett's Green is covered, for single jobs and planned programmes alike. We work across 308 places in East Sussex. Brighton is covered too, some 27 miles away.

When it isn’t the sealant

Honesty saves time and money. New sealant won’t cure:

  • Proprietary pre-formed expansion joint systems
  • Structural movement beyond what the joints were designed for (that needs a structural engineer)
  • Crumbling edges that would give a new bead nothing sound to grip

If in doubt, speak to us on 01277 525 020 or email drawings and photos and we will say what we think before you book.

Surfaces we seal

  • Brickwork movement joints
  • Precast concrete panel joints
  • Car park decks and ramps
  • Blockwork control joints
  • Podiums and floor movement joints
  • Cladding panel joints

Keeping the joints sound

Cleaning and maintenance staff play a part too. Pass these on to them:

  • Inspect movement joints alongside other routine building checks
  • Look over external and deck joints after a hard winter
  • Avoid parking heavy plant or pallets on joint lines
  • Clear dirt from joint lines during routine cleaning

Debris does more harm to joint sealant than most people realise. Stones pressed into the bead by wheels or feet can puncture it, especially on car park decks and warehouse floors. A routine sweep is the simplest protection.

An open joint fills with grit, and a joint full of grit can’t close. The arrises crack and break away under the load and the reseal becomes an edge repair as well. A sound seal keeps the joint working.
