Questions about Netley

Our building in Netley is near the coast: does that change the sealant?

It can. Wind-driven rain and, closer to the shore, salt air are harder on external joints. We check the specified product suits the exposure and pay close attention to preparation.

Can you work at a site such as Ensign Way Business Park, by Netley?

Yes. Estates, retail parks and business parks around Netley, Ensign Way Business Park among them, are all within reach. To start, just give us a call on 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.

How long will the new sealant last?

It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.

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.

Can weather delay the job?

It can, when the joints are outside. Sealant won’t bond properly to a wet or frosty joint, so external work may be moved if conditions aren’t right. Internal work is far less affected.

Are your applicators CSCS-carded?

Yes. If you need card details for site access, let us know and we’ll send them with the quote.

What guarantee do you give on resealing?

The work is guaranteed for 12 months. Should a joint we sealed give trouble during those 12 months, let us know and we’ll look at it.

About our commercial sealant contractors in Netley

Most commercial buildings carry hundreds of metres of sealant that nobody thinks about until it fails, and in an occupied building failure usually announces itself as a stained ceiling or an unhappy tenant. Mastic Doctor works as a commercial sealant contractor for facilities managers, managing agents and main contractors with sites in Netley. Our job is to diagnose the failure, remove the old bead and seal again using a product chosen for the movement and exposure. If you have movement joints packed with grit and debris and messy, uneven beads from earlier work that let the building down, we can help, whatever the surface. One point of contact handles commercial sealant work in Netley from the first photos to the final walk-round, whether it’s one building or several.

Quotes for commercial sealant in Netley can come from photos and a joint schedule, or from a walk-round, and the scope is set out in writing.

Sealant jobs for businesses in a place the size of Netley are often best grouped: frontage, staff facilities and window perimeters on one booking. Fewer visits means less disruption to trading, and where colour matters on the frontage, we will confirm what’s available for the product.

A 12-month guarantee applies to all our work. If an installation problem shows up, speak to us on 01277 525 020 or use the quote form and we’ll arrange a return visit.

What happens if it’s left?

Before budgeting for new frames, cubicles or worktops, check whether it’s just the sealant. In many cases the element is fine and only the seal around it has given up. Resealing typically costs far less than renewal, though we will tell you honestly if the element itself is the problem. In a smaller place such as Netley, getting a contractor back for a second visit takes time, so it’s worth dealing with every failing joint at once.

Every site prices differently: joint size, product, access and site hours all play a part. Send the details and a fixed figure follows.

Surface by surface

Fire-rated seals where specified

Not every penetration suits a sealant. Collars, wraps, batts and boards are specified for other services and gaps.

Movement joints in walls and floors

Floor joints that take trolleys or forklifts need a tougher filler or sealant. The choice comes down to how much the joint moves and what runs over it; if the arrises are broken, we will say so before sealing.

Sealant on show in Netley’s commercial buildings

The sea is no more than about 1 mile from Netley. For shops, hotels and offices, that means frontage and frame joints that weather faster than they would inland. Sea-facing elevations are typically where failed joints show first. Netley is about 69 miles from central London. This part of the South East is dense with business parks and out-of-town offices. If you have premises across the region, one contractor can cover them all.

Offices and shops close to stations such as Netley station (less than half a mile south-east of Netley) tend to be busy all day, so sealant work is planned around opening hours. If you have premises on more than one site, say at Ensign Way Business Park and Basepoint Business Centre, one contractor and one quote can cover both. Parks like Ensign Way Business Park (1.6 miles south-east of Netley) see tenants come and go, and every move-in brings joints to seal.

Netley is about 3 miles north-east of Hythe, in Hampshire. We cover commercial sites throughout Netley. Netley is one of 723 places we cover in Hampshire.

Work on sealant joints is covered throughout SO31, whatever the building. For a building on Station Road, The Crescent and Hunt Avenue or nearby, we can quote for sealant joints. If your building is just outside Netley, we cover Butlocks Heath (1 mile north-east), Hound (1 mile south-east), Weston (1 mile north-west), Old Netley (1 mile north-east) and Lowford (1 mile north-east). Further afield, our area takes in Winchester (13 miles north), Gosport (10 miles south-east), Eastleigh (6 miles north), Fareham (7 miles east), Horndean (15 miles east) and Totton (8 miles west).

What’s near Netley

We work on buildings around Grove Park Business and Enterprise College, Westwood Woodland Park and The Hamble School and the streets around them. There’s a railway station in Netley itself: Netley station. A little further out are Bursledon Brickworks Industrial Museum (2.5 miles east) and Coldeast (2.8 miles east). For a walk, there’s Mercury Marshes.

Keeping the joints sound

Sealant joints are maintenance items, and how long they last depends on how they’re treated. We suggest:

  • Add sealant to the planned maintenance inspection list
  • Make sure contractors see the asbestos survey before cutting out old mastic
  • Deal with small splits before they become leaks
  • Keep barriers up until the new sealant has cured

Our workmanship on each job is backed by a 12-month guarantee. Keep the handover details with your O&M or maintenance records.

Each spell of wet weather pushes more water through an open joint. It can run into cavities, insulation and internal finishes long before anyone sees a stain. Catching it at the sealant stage avoids the bigger repair.

Our process

A typical day starts with protection: tape along each joint edge and covers over finishes, stock and equipment close by. The work itself usually takes anything from part of a day on a short run of joints to several weeks on a large phased package, and we clear our waste as we work. If neighbouring businesses or buildings around Netley need work too, visits can be combined. Tell us your site hours and we will plan around them.

  1. You send photos, drawings or a list of the joints and areas involved, or we arrange a site visit.
  2. The failure is diagnosed and a fixed quote issued for the work agreed.
  3. Site hours, access windows and the order of areas are agreed before we start.
  4. Failed sealant is cut out and each joint cleaned back to sound, dry faces.
  5. Backing and primer go in where needed, then the chosen sealant is applied and tooled.
  6. Each area is inspected, signed off and backed by our 12-month guarantee.

What we need from you

  • Let building users know which areas are affected
  • Arrange parking or a loading space
  • Clear stock, furniture or equipment away from the joints

Request a quote

Related advice

Site staff or a sealant specialist?

There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.

Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.

What sets the cost

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

  • Any access equipment needed
  • Removal of failed or old sealant
  • Phasing around occupants
  • Which sealant the job calls for

A quote for sealant joints depends on quantities, condition and access. Ask us for a fixed quote.

What to include in your enquiry

Diagnosis starts before we arrive. Tell us:

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