Common questions from Pennington clients

Do you take on work at healthcare sites like Lymington New Forest Hospital?

Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Can being near the sea in Pennington affect the sealant we need?

It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. Product choice and preparation matter more, and sea-facing elevations are worth inspecting more often.

Can one quote cover more than one building?

Yes. Several buildings can share a single quote, with one point of contact.

Can the sealant be colour-matched?

Often, yes. Sealants are made in a wide range of standard colours, and matching to RAL references or nearby finishes is commonly requested. We confirm what’s available for the specified product when we quote.

Do you use silicone or polyurethane in movement joints?

The specification comes first, then the joint’s movement and exposure. The quote states the sealant and its movement class so there are no surprises.

Can you work to our specification?

Yes. Send it with your enquiry, and the quote will be based on it.

Are you insured?

Yes. We’re fully insured, including public liability cover.

Expansion joint sealing in Pennington, done properly

We cover the full range of movement joints: vertical joints in brick and block facades, joints between precast or cladding panels, concrete slab and deck joints, ramps, podiums and internal floors. The product depends on the movement, the weather and anything that runs over it. We work on blockwork control joints, brickwork movement joints and podiums and floor movement joints, and the usual reasons a site gets in touch are spalled or broken joint edges in floors and decks and joints packed with grit and debris. Sealant applicators who only do sealant are a different proposition from a general trade with a gun in the van: on jobs in Pennington, preparation and product choice get the time they need.

Around places the size of Pennington, joints that need sealing tend to be in rural business units, farm buildings put to commercial use, schools and community buildings. Their slabs and walls still need movement joints that work.

Work we carry out comes with a 12-month guarantee. If an installation problem shows up, phone 01277 525 020 or send details through our quote form and we will arrange a return visit.

Looking after the joints

Once the work is signed off, these steps help:

  • Plan racking layouts so feet don’t land on a joint
  • Inspect movement joints alongside other routine building checks
  • Leave barriers in place until fresh joint sealant has cured
  • Keep product details with the building records for the next reseal

In warehouses, forklift and pallet-truck routes take the most wear. Avoid standing heavy loads or racking legs on the joints and flag chipped arrises before they spread.

External wall joints that fail let rain into the masonry and cavity. It can surface inside as damp a long way from the joint by which time the joint has been open for a while. Catching it early keeps the water outside.

What happens if it’s left?

Some quotes just add sealant over the old bead. A bead laid on top of the failed one neither grips nor flexes properly, so it fails quickly. We cut out the old seal and prepare the faces every time. For buildings in places like Pennington, one well-planned visit beats several small ones, so we’d suggest renewing all the joints that are going, not just the worst.

Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote, and you’ll have a fixed figure to work with.

On site: what to expect

Working in a building that stays open takes some planning. We sign and contain the area we’re in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. What matters most for a job in Pennington is a clear list of what needs doing. You’ll then get a fixed price for the work.

  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. Where areas have to stay open, we agree a phased sequence before starting.
  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.

What we need from you

  • Clear stock, furniture or equipment away from the joints
  • Tell us what induction or permit system the site runs
  • Confirm the product named in the specification

What we can’t put right

We seal joints; we don’t mend everything behind them. Sealant alone won’t deal with:

  • Movement on a scale no sealant is meant to absorb
  • Leaks coming from the membrane rather than the joint seal
  • Changing the joint layout or spacing of a structure

If in doubt, phone 01277 525 020 or email a schedule or drawings and we’ll say what we think.

Surfaces we seal

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

What affects the price in Pennington

To price the job, we consider:

  • Specialist products, such as fire-rated or hygienic sealants
  • Any access equipment needed
  • Distance, for remote addresses
  • Site requirements such as inductions and permits

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. Send the details and a fixed figure follows.

What we need to price the job

The more we know, the firmer the quote. When you get in touch, include:

  • Whether an asbestos survey exists
  • The site address and postcode
  • The type of building and who uses it
  • When you need the work done

Quotes are fixed against the scope you send, so the cost is agreed before work starts. To ask for one, give us a call on 01277 525 020 or email drawings and photos.

What the job involves on each surface

Cladding panel joints

Access to cladding joints is agreed before the price is fixed. Photos taken near the joints help us price accurately, or we visit if they don’t show enough.

Internal floor movement joints

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

Joints that move: notes for Pennington

Pennington is within about 1 mile of the coast. Open joints in coastal car parks and yards let in salt-laden water as well as grit, and edges left open tend to break up faster. Pennington 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, and winter de-icing salt on car parks and ramps works into any open joint.

For an estate such as Lymington New Forest Hospital, 1.4 miles to the north of Pennington, the joints in ramps, decks and long building elevations all need attention over time. For a school such as Priestlands School, playground and building joints can be done in the holidays.

Pennington is about 1 mile south-west of Lymington, in Hampshire. Anywhere in SO41, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed. Pennington is one of 723 places we cover in Hampshire. Southampton is covered too, around 14 miles from Pennington.

Postcode districts covered here: SO41. For a building on Mead Road, Pound Road and Elm Avenue or nearby, send details and we’ll quote for movement joints. Sites close to Pennington are covered too, including Lymington (1 mile north-east), Lower Pennington (1 mile south), Walhampton (1 mile north-east), Everton (1 mile west) and Lymore (2 miles south-west). Bigger towns within reach include Totton (12 miles north), Hythe (10 miles north-east), New Milton (5 miles west), Ringwood (12 miles north-west), Locks Heath (15 miles north-east) and Warsash (14 miles north-east).
