Expansion joint sealing for Whitehill sites

Send drawings, photos or a joint schedule, or tell us about the site, and we’ll come back with a fixed quote.

Surface by surface

Podium joints

Podium decks are exposed and often trafficked. A sealant suited to both traffic and exposure is used.

Internal floor movement joints

Forklift and pallet-truck wheels break unsupported joint edges. We match the product to the traffic and the movement.

Expansion joint sealing in Whitehill, done properly

Every structure moves a little, all the time: temperature, moisture, shrinkage and loading all make materials grow and shrink. Expansion and movement joints are built in so the structure can move without cracking. We seal and reseal movement joints in walls, panels, decks and floors. The enquiries we see most involve expansion joints filled with dirt and stones and weathered movement joint sealant that no longer flexes, across blockwork control joints, podiums and floor movement joints and brickwork movement joints. Looking for mastic applicators who cover Whitehill? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

Around Whitehill, most floor and movement joint jobs are single buildings or yards, so we gather photos and measurements first. That way the right materials come on the day and the job is done in one visit where possible.

Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Questions about Whitehill

Is Whitehill too far out for you?

No. Small places get the same service as large ones. London and every South East county are within our area. Send photos and a list of what needs doing, and we will plan the job to need as few trips as possible.

Can you take on a job at a hospital such as Chase Hospital?

Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.

Which sealant will you use?

Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Will you come and look before quoting?

It depends on the job. Straightforward work can often be priced from photographs and measurements, while larger or less clear jobs get a site visit first.

Why do our movement joints keep failing?

Most often the movement is too much for the product or the joint width. That’s why we check width, depth and movement class before quoting so the same failure isn’t repeated.

Is movement joint sealing guaranteed?

The 12-month guarantee applies to the workmanship. If a joint we sealed fails inside the 12 months, let us know.

Is any job too small?

Small jobs are welcome alongside larger packages. Photos and a description are enough to start.

For managing agents and facilities managers

CHAS accredited and a Constructionline member, we’re straightforward to vet for your supplier list. We are fully insured, and our insurance certificate can go with the quote.

Blocks and communal areas make up much of the work for housing associations and agents. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

Keeping the joints sound

Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:

  • Brief car park operatives to protect joint lines during winter clearance
  • Include every elevation and deck joint in periodic inspections
  • Treat a small split as a warning, not a cosmetic issue
  • Keep traffic off new joints until the cure time is up

Snow ploughs and scrapers catch on joint lines. Lifting the blade at each joint avoids tearing the bead, and it’s worth checking joints once the cold weather has passed.

Rain gets into walls through torn brick and block movement joints. The first sign is often a damp patch indoors by which time the joint has been open for a while. Catching it early keeps the water outside.

When to bring in a specialist

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong usually costs more in the end than doing them right.

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.

Diagnose, treat, sign off

Before we leave any area, we remove the tape, clean down and inspect every joint, ready for your sign-off. Where the sealant needs time to cure before use, we tell you and sign the area. What matters most for a job in Whitehill is a clear list of what needs doing. You will then get a fixed price for the work.

  1. The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
  2. You get a fixed quote with the product and its movement capability stated.
  3. The failed seal is removed and both faces are cleaned until sound and dry.
  4. Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
  5. After any primer the maker requires, the bead is applied and tooled so it grips two sides only.
  6. Finished joints are checked and backed by our 12-month guarantee.

Preparing the site

  • Share your working hours and any access restrictions
  • Send any specification or drawings in advance
  • Send asbestos survey details if the building is pre-2000

Quotes

Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photographs and a few notes.

Expansion joint sealing in Whitehill: the local picture

Whitehill sits in one of the drier corners of the country, the South East. Even so, yard and car park joints are only sealed when they’re dry and clean, while winter salting gets into any joint left open. The 3 miles around Whitehill take in at least three named trading estates, business parks or retail parks. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest.

For an estate such as Chase Hospital (under half a mile north-east of Whitehill), the joints in ramps, decks and long building elevations all need attention over time. If you manage units on an estate such as Woolmer Trading Estate (under half a mile north of Whitehill), the floor joints under forklifts and pallet trucks and the slab joints in the yard are the ones to watch. In a school such as Woodlea Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak.

Whitehill is about 6 miles south-east of Alton, in Hampshire. Any commercial site in Whitehill is covered, whether it’s a single job or part of a planned programme. Our Hampshire coverage takes in 723 places, from busy centres to rural villages. We also cover Portsmouth, some 22 miles away.

If you need expansion joint sealing in GU35, the process matches everywhere else we work: send details, get a quote, we seal, guaranteed. Among the streets we cover are Stubbington Avenue, Petersfield Road and Dudley Close. We also cover Hollywater (1 mile east), Bordon (1 mile north), Deadwater (1 mile north-east), Pinewood Village (1 mile north) and Standford (1 mile east) for movement joints. Bigger towns within reach include Basingstoke (15 miles north-west), Farnborough (14 miles north), Fleet (12 miles north), Horndean (15 miles south-west), Aldershot (11 miles north-east) and Alton (6 miles north-west).

Around Whitehill

Around Whitehill, our work takes us to commercial buildings near St Matthew's Church and Mill Chase Academy. Whitehill’s nearest station is Liphook station, roughly 3.7 miles south-east of the centre. A little further out are The Romany Museum (3.2 miles west) and Chase Community Hospital (under half a mile north-east). The countryside around Whitehill includes Selborne Hill and Deadwater Valley.
