Commercial sealant contractors for commercial buildings in Netley Marsh

A reseal stands or falls on the preparation underneath it. Silicone has no grip on cured silicone, so the failed bead is cut out completely. Primer is used wherever the manufacturer calls for it on that surface. If you are dealing with sanitary sealant that has gone black and patchy and expansion joints with the sealant torn out, we can put it right, whatever the surface. For commercial sealant work in Netley Marsh, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

The most common commercial job in Netley Marsh is resealing joints that have simply reached the end of their life: split, chalky or peeling, with leaks or mould starting behind it.

Work in smaller places such as Netley Marsh tends to come one building at a time: a pub kitchen, a hall, a small office. We plan the visit so everything on the list is done in one go, with the right products and colours on hand.

A 12-month guarantee applies to all our work in Hampshire. If an installation problem shows up, call the office on 01277 525 020 or send photos by email and we’ll arrange a return visit.

How the quote is worked out

These are the things that shape the price:

  • Site requirements such as inductions and permits
  • Travel to remote or island sites
  • Backing rod, priming and other preparation
  • Specialist products, such as fire-rated or hygienic sealants

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

What to include in your enquiry

Diagnosis starts before we arrive. Tell us:

  • Asbestos survey details if the building is older
  • Where the site is, with the postcode
  • The product your specification calls for
  • How the joints are reached, and at what height

We quote a fixed sum against the scope you give us, so the cost is agreed before work starts. To start the process, phone 01277 525 020 or email drawings and photos.

Common questions from Netley Marsh clients

Does the sea air around Netley Marsh change the choice of sealant?

It can, yes: buildings near the sea take more wind-driven rain, and salt in the air nearer the shore. We check the specified product suits the exposure and pay close attention to preparation.

Is Netley Marsh too far out for you?

No. Places such as Netley Marsh are covered as much as the big towns. London and every South East county are within our area. Good photographs up front let us bring everything on the first visit.

Do you work for facilities managers and managing agents?

Yes, and through main contractors too. You send the details, we return a fixed quote, and the job is done and signed off, with a 12-month guarantee on the workmanship.

Does commercial sealant work come with a guarantee?

Our workmanship is guaranteed for 12 months. We are fully insured for public liability as well.

How do we get a quote?

The main factors are metres of joint, removal, access, the product and how many phases there are. For a fixed quote, send details through our quote form.

Do you seal on top of existing sealant?

No, never. Sealing over old material is one of the classic causes of early joint failure, so everything comes out first.

Is the old sealant taken out first?

Removal of the failed sealant is always part of the job. New sealant can’t grip the old bead, so laying over it never lasts, and the faces are brought back to sound, dry material before resealing.

Commercial sealant contractors in Netley Marsh: the local picture

The sea is no more than about 3 miles from Netley Marsh. Shopfronts, frames and external joints on commercial buildings there take wind-driven rain and, closer to the shore, salt in the air. A matched colour is only half the brief on an exposed frontage. The 3 miles around Netley Marsh take in at least three named trading estates, business parks or retail parks. Tenant changes on such sites bring fit-outs, and fit-outs bring new joints.

For premises near Ashurst New Forest station, 1.8 miles to the south of Netley Marsh, footfall is part of the plan: work is phased so shops and offices keep trading. Sites a few miles apart, such as Rushington Business Park and South Hampshire Industrial Park, can share one programme and one point of contact. For a hotel such as Woodlands Lodge New Forest Hotel, which lies south-west of Netley Marsh, the colour of a joint at the bar or the bath matters to the look of the room.

Netley Marsh is about 1 mile west of Totton, in Hampshire. Any commercial site in Netley Marsh is covered. Netley Marsh is one of 723 places in Hampshire on our list. For work in that direction, see our Southampton page (6 miles or so).

Work on sealant joints is covered throughout SO40. Streets here include Ringwood Road and Woodlands Road. We also cover Ashurst Bridge (1 mile south-east), Totton (1 mile east), Woodlands (1 mile south), Winsor (1 mile north-west) and Bartley (1 mile west). Bigger towns within reach include Winchester (14 miles north-east), Eastleigh (9 miles north-east), Fareham (15 miles east), Chandler's Ford (8 miles north-east), Hedge End (10 miles east) and Lymington (11 miles south).

Owners, agents and contractors

Hotels, schools, healthcare sites, offices and retail units come to us directly as well. The work is planned around how the building runs, so the building keeps working while we do.

FMs need a contractor who is easy to get on site. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we will confirm with the quote.

General trades versus a specialist

For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.

Redoing a failed joint usually costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

Diagnose, treat, sign off

Tell us your site hours and access windows and we will plan around them. While we’re working, the area stays contained and tidy, and your contact hears from us before we move to the next area. Jobs in and around smaller places like Netley Marsh are typically planned as a single visit, so we ask for photographs and rough sizes first. That way the right products come on the day.

  1. Send details through our quote form, or ask for a site visit.
  2. We diagnose the cause of failure and price a fixed scope.
  3. Where parts of the building must stay open, the work is phased.
  4. Every failed bead is removed rather than covered.
  5. A suitable product for each joint goes in at the right depth and is tooled.
  6. A final walk-round, then the 12-month guarantee applies.

Before we start on site

  • Tell us your opening times and when work is allowed
  • Move anything stored against the joints
  • Flag any permit to work we will need

Getting a fixed quote

Photos, drawings or a schedule of the joints are often enough for a fixed quote. Where a site visit makes more sense, we will arrange one.

Advice

Why deal with it now?

Some low prices are low because nothing gets cut out. Sealing over looks tidy at handover, then lifts once the joint starts moving. Our prices always include removal of the failed bead and full joint preparation, which is where the lasting value is. Halls, stores and units around places like Netley Marsh may not be checked every day, which gives a failed joint time to do damage. Resealing early avoids that.

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 fixed quote.

Why us?

  • Workmanship guaranteed for 12 months
  • Colour options checked against the specified product
  • CHAS accredited
  • Our applicators hold CSCS cards

Keeping the joints sound

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

  • Make sure ventilation in wet areas is switched on and working
  • Look at the sealant around anything that has been moved or replaced
  • Report cracked or peeling sealant early
  • Keep abrasive pads and scrapers off resealed joints

New joints need their full cure time before they take water, cleaning or traffic. That time depends on the product, the temperature and the joint depth, and we confirm it when each area is handed back. Keeping signs or barriers up until then protects the finish.

Movement joints that fill with debris stop working. The joint can no longer close, so its edges crack or spall. That turns a sealant job into something bigger.
