How we handle expansion joint sealing in Hamsey

Buildings and slabs are never completely still: they expand in the heat, shrink as they dry, and shift under load. Movement joints are where that movement is absorbed. Mastic Doctor reseals movement joints in brickwork, blockwork, concrete, cladding and floors for buildings in Hamsey. If you have debris jammed in movement joints and sealant peeling off one face of the joint, we can put it right, whatever the surface. One point of contact handles commercial sealant work in Hamsey from the first photos to the final walk-round, whether it’s one building or several.

In and around smaller places like Hamsey, the concrete floors we see are often in converted farm buildings, small workshops and storage units. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.

Our workmanship is guaranteed for 12 months, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

How the quote is worked out

What shapes the price:

  • Phasing around occupants
  • Backing rod, priming and other preparation
  • Location, for remote and island sites
  • Site requirements such as inductions and permits

The work involved drives the cost: removing old material, preparing the joints, the product, the access and how the work is phased. Call for a quote.

Details that help us quote

For an accurate fixed quote, we need to understand the site. Useful things to include:

  • Photos of the joints, close up and from further back
  • When you need the work done
  • Drawings or a marked-up plan, if available
  • Whether an asbestos survey exists

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, call the office on 01277 525 020 or email the details over.

Should maintenance staff do it?

Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.

A short, simple internal joint is often within reach of a maintenance team. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.

Work for main contractors and building owners

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

Different surfaces, different methods

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 flagging broken edges along the way.

Internal floor movement joints

Warehouse and retail floors have saw-cut induced joints and construction joints. Trafficked floor joints often get a semi-rigid filler.

Your questions answered

Can you work at a site such as Malling Industrial Estate, by Hamsey?

Yes. We cover Hamsey and the area around it, including industrial estates, business parks and retail parks such as Malling Industrial Estate. A few photographs and the unit address let us price the work.

Is Hamsey too small for you to travel to?

Not at all: smaller places are covered as well as towns. Our area covers London and the South East counties. Where we can, we group nearby jobs to make the most of each trip.

How do I request a quote?

The quote form is the simplest route, though you can also speak to us on 01277 525 020 or send photos by email. Photos, drawings or a joint schedule help us quote quickly.

How long do sealant joints last?

It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.

What happens if it rains on the day?

Outside work depends on conditions: rain, frost and condensation all stop sealant bonding. Internal floor joints are far less affected.

What’s the difference between an expansion joint and a movement joint?

The general name is movement joint, and expansion joint is one common type. On site, people tend to use them interchangeably.

Do you take on small jobs?

Whatever the size, the process is the same: details, then a fixed price, then sealing, then a 12-month guarantee.

Traffic, movement and joints around Hamsey

At about 42 miles from central London, Hamsey is within reach of the capital. The roads out of London are lined with trade parks and distribution sheds. Rainfall across the South East, Hamsey included, is lower than in many parts of the UK. External joints still wait for dry conditions, while winter salting gets into any joint left open.

Schools such as Hamsey Community Primary School have movement joints in their walls and floors that are easy to overlook. A healthcare site such as Lewes Victoria Hospital, 1.5 miles south of Hamsey, depends on car parks, ramps and service yards whose joints take traffic all day. At places like Riverside Industrial Estate, 1.3 miles south of Hamsey, joints are sealed a section at a time so operations carry on.

Aftercare for building managers

Keep the joints in good shape with a few simple steps:

  • Brief car park operatives to protect joint lines during winter clearance
  • Look over external and deck joints after a hard winter
  • Note which joints were done, when, and with what
  • Avoid parking heavy plant or pallets on joint lines

Grit is the slow enemy of a joint seal. Grit trodden or driven into the joint works at the surface until it tears and decks and floors suffer most. Regular sweeping keeps joint lines clear.

Floor joints with failed fillers break up quickly under wheels. Broken arrises jolt trucks, loads and drivers and the broken length grows with every pass. Keeping the filler or sealant sound protects the floor.
