Need commercial sealant contractors in Holbury?

Share the site address and what’s failing, and we’ll reply with a fixed quote or arrange a visit.

Diagnose, treat, sign off

Inspect, seal, sign off: every visit follows that pattern. We inspect the joints and confirm what’s in scope, then we prepare and seal each joint with the specified product, and we finish with a walk round so the work can be signed off. For a job in Holbury, the main thing is a clear picture of the work, so send photos of each area. You will then get a fixed price for the work.

  1. First, details come to us: photos, drawings or a schedule of the areas, or we arrange a site visit.
  2. The failure is diagnosed and a fixed quote issued for the work agreed.
  3. Before anything is cut out, we agree access, timings and sequence.
  4. Failed sealant is cut out and each joint cleaned back to sound, dry faces.
  5. We fit backing to the right depth, prime where specified and lay the new bead.
  6. We walk the completed areas with you and sign them off under the 12-month guarantee.

Before we start on site

  • Point out any areas we must not close
  • Arrange parking or a loading space
  • Have the specification and drawings to hand

Commercial sealant contractors in Holbury

If you look after more than one building, a single sealant contractor saves a lot of chasing. Single jobs, multi-site packages and planned programmes all come to us, handled with the same process each time: details in, a fixed quote back, the sealing done, then our 12-month guarantee. For sites in Holbury, the quickest start is to call the office on 01277 525 020 or email drawings and photos with a list of addresses. If you have expansion joints with the sealant torn out and external beads that have gone brittle and cracked, we can help, whatever the surface. Whether you call it commercial sealant work, mastic application or joint sealing, the work in Holbury is the same: the right product in a properly prepared joint.

On a typical commercial building in Holbury, the joints that fail first are the hardest-worked ones: south-facing perimeters, entrance thresholds and busy washrooms.

For a business in Holbury, it usually makes sense to put the sealant work into one visit: shopfront, washroom, kitchen and any external joints done together. That keeps travel and disruption down, and where colour matters on the frontage, we’ll confirm what’s available for the product.

Every job we finish is backed by a 12-month workmanship guarantee, in Holbury as everywhere else we work. If a joint we sealed fails because of how it was installed, we come back and put it right.

Commercial premises in Holbury

Holbury lies within about 2 miles of the sea. For shops, hotels and offices, that means frontage and frame joints that weather faster than they would inland. Where a frontage needs a particular colour, the product still has to suit that exposure. The area within 2 miles of Holbury holds several hotels. Hotel refurbishments are where a matched sealant colour earns its place: bathroom, bar and reception joints have to sit with the finishes; work is planned so the hotel keeps trading.

For premises near Netley station (3.8 miles north-east of Holbury), footfall is part of the plan: work is phased so shops and offices keep trading. If you have premises on more than one site, say at Glenmore Business Park and Hardley Industrial Estate, one contractor and one quote can cover both. For tenants and agents on sites such as Glenmore Business Park, 1 mile to the north-west of Holbury, office fit-outs, reception joints and window perimeters are the usual sealant work.

Holbury is about 2 miles south of Hythe, in Hampshire. If you’re looking for commercial sealant contractors in Holbury, we can help, as we do across Hampshire.

Cost factors for sealant joints

Your fixed quote is built from the real scope. It takes account of:

  • Removal of failed or old sealant
  • Phasing around occupants
  • The product specified
  • Joint width, depth and condition

There’s no price list, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we will price your job on its own details.

What to include in your enquiry

We can often quote from photographs and a few details. It helps to include:

  • The postcode of the building
  • Drawings or a marked-up plan, if available
  • The asbestos register, for older buildings
  • Whether the building will be occupied during the work

Quotes are fixed against the scope you send, so you know the figure before anyone is on site. To ask for one, call 01277 525 020 or email a schedule or drawings.

Site staff or a sealant specialist?

Redoing a failed joint normally costs more than getting it right at the outset, 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.

General builders and handymen seal joints, but it isn’t their main trade. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Questions we are asked in Holbury

Is Holbury 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. We plan jobs in smaller places so return trips are kept to a minimum.

Will our hotel in Holbury need to close for the work?

Rarely, if ever. We take a few rooms out at a time. Housekeeping and our team agree each day’s rooms.

Who decides which product is used?

If the job is specified, we follow the specification. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.

Can you work to our specification?

Yes. We follow the specification, along with the manufacturer’s installation guidance.

How do we get a quote?

Send what you have, even a few photographs and rough lengths. We follow up with questions or a visit where needed, then a fixed quote.

Do your applicators hold CSCS cards?

Yes. If you need card details for site access, tell us and we will confirm them with the quote.

Will the building have to shut during the work?

We phase the work so parts of the building stay open. We plan around the site hours and access windows you give us.

Keeping the joints sound

A few simple habits keep the new joints working:

  • Add sealant to the planned maintenance inspection list
  • Keep barriers up until the new sealant has cured
  • Make sure ventilation in wet areas is switched on and working
  • Ask fit-out and M&E contractors to report any sealant they disturb

Put sealant on the planned maintenance checklist. A periodic look catches splits and lifting edges early. If anything looks wrong, phone 01277 525 020 or send photos by email with a photo.

Sealant rarely fails all at once across a building. A few splits this year normally mean more next year. We can assess the lot and suggest what to do now and later.

What happens if it’s left?

Patching the worst lengths can be the right call on a tight budget. Where the remaining sealant is just as old, it tends to fail soon after. We can price both options so you can decide on the facts. Sealant hardens, cracks and loses grip with age, UV and movement. Renewing it in good time keeps the building weathertight.

A quote for sealant joints depends on quantities, condition and access, and any specification that applies. Call for a quote.

What the job involves on each surface

Movement joints in walls and floors

Floor joints that take trolleys or forklifts need a tougher filler or sealant. We will recommend the right filler or sealant for the traffic and movement.

Washrooms and toilets

Black sealant in a toilet block is normally beyond cleaning. The lasting answer is removal, preparation and a new sanitary bead.
