Expansion joint sealing for businesses in Hound

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

Expansion joint sealing in Hound, done properly

For movement joints in Hound, photographs and approximate lengths are the best start. Send them through our quote form, and we’ll arrange a site visit if needed, then send a fixed quote that names the sealant. You can also speak to us on 01277 525 020 or send details through our quote form to talk the joints through. We work on podiums and floor movement joints, cladding panel joints and blockwork control joints, and the usual reasons a site gets in touch are joints where the bead has lost adhesion and previous reseals laid over old sealant. Looking for mastic applicators who cover Hound? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.

Jobs around smaller places like Hound are planned so the whole job is done in one visit, with the right materials on hand. Note joint widths and the traffic that uses them, and we’ll take it from there.

Work we carry out in Hampshire comes with a 12-month guarantee. If an installation problem shows up, give us a call on 01277 525 020 or email the details over and we will arrange a return visit.

How a job runs

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, primer goes on where the manufacturer specifies it, and the sealant is tooled off neatly. Smaller jobs around Hound can be grouped with others nearby. A fixed quote is given before anything starts.

  1. First the joints are inspected, widths measured and the type of failure noted.
  2. You receive a fixed quote stating the product and the movement it is rated for.
  3. Phasing is agreed so decks, floors or entrances can stay in use where needed.
  4. We strip the old sealant or filler and prepare each face until it’s sound and dry.
  5. Depth is controlled with backing, the faces are primed where the maker calls for it, then the bead is laid and tooled.
  6. Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.

Preparing the site

  • Arrange parking or a loading space
  • Clear stock, furniture or equipment away from the joints
  • Share your working hours and any access restrictions

What we are called out for in Hound

On trafficked joints, wheels and salts do the damage. Wheel loads stress the sealant and the arrises, while grit and salts work into any gap. The product has to be suited to the traffic.

It’s worth sending us details if you spot any of the following:

  • Leaks through car park deck joints onto the level below
  • Spalled or broken joint edges in floors and decks
  • Torn sealant in brick or block movement joints
  • Rain penetration at brick or block movement joints

For a school such as The Hamble School, playground and building joints can be done in the holidays.

What to look for in a quote

  • Do they follow the manufacturer’s priming guidance?
  • Will CSCS-carded applicators be on site?
  • What site paperwork they can supply
  • Can the work be phased to keep areas open?

How to choose a sealant contractor

After the work

Cleaning and maintenance staff play a part too. Share these points with them:

  • Note which joints were done, when, and with what
  • Inspect movement joints alongside other routine building checks
  • Clear dirt from joint lines during routine cleaning
  • Keep scrapers and ploughs from dragging across joint sealant

Grit is the slow enemy of a joint seal. 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.

External wall joints that fail let rain into the masonry and cavity. The first sign is often a damp patch indoors, well after the seal first opened. Catching it early keeps the water outside.

Your questions answered

Does your area include sites such as Ensign Way Business Park, near Hound?

Yes. Our area takes in Hound and its surroundings, with estates and business parks such as Ensign Way Business Park included. Send details of the unit and the work through our quote form for a quick quote.

Is a hospital such as Fareham Community Hospital somewhere you can work?

Yes. Healthcare sites are among the places we work. Work is phased so departments keep running, under the site’s own rules.

Are you CHAS accredited and on Constructionline?

Yes. We’re CHAS accredited, we are a Constructionline member and we use CSCS-carded applicators.

Does weather matter for sealant work?

For external joints, yes. Sealant needs a dry joint and a temperature within the product’s range, so damp, frosty or very cold days can stop external work. Inside work is seldom held up.

Will you just go over the old sealant?

No. Failed sealant is removed and the faces cleaned back to sound, dry material first, since fresh sealant will not bond reliably to aged material.

How do we ask for a quote?

You can use the quote form on this site; alternatively, call 01277 525 020 or email the details over. Photos, drawings or a joint schedule help us quote quickly.

Do you offer coloured sealant?

That depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.

What the job involves on each surface

Cladding panel joints

Metal and composite panels shift considerably as temperatures change. A sealant with the right movement class is chosen.

Brickwork and blockwork joints

Brick and block edges need careful preparation. Faces are prepared and primed wherever the sealant maker calls for it.

Warehouse floors and decks around Hound

The sea is no more than about 1 mile from Hound. Near the sea, external slabs, ramps and decks see salt air and driven rain as well as their usual loads, so a failed joint lets more in and the edges break up sooner. Less than 3 miles from Hound there are two named estates and business parks. Floors, loading bays and yards on sites like these are where floor and movement joints work hardest.

Campuses like Southampton Solent University (3.6 miles north-west of Hound) mix old and new buildings, with movement joints wherever they meet. For buildings at a park such as Ensign Way Business Park (1.2 miles south of Hound), brick and panel movement joints are easy to forget until one leaks.

Hound is about 3 miles east of Hythe, in Hampshire. We send applicators to Hound for movement joints. Hound is one of 723 places in Hampshire on our list.

When it isn’t the sealant

Sealant solves a lot, but not everything, and we are upfront when that’s the case. These need a different solution:

  • Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
  • Changing the joint layout or spacing of a structure
  • Structural movement beyond what the joints were designed for (that needs a structural engineer)

If in doubt, call 01277 525 020 or email the details over and we’ll say what we think before you book.

What we seal

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

Leave it or put it right?

Sealing over a failed movement joint is a common shortcut. A bead over the old seal can’t bond or flex and soon lets go. Full removal and preparation is in every quote. For buildings around smaller places like Hound, water damage can go unnoticed for longer, especially where a building isn’t used daily, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.

What a job costs comes down to the quantity of joints, how much old material needs removing and the access. Call for a quote once you have the details.
