Facade sealing in Netley

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

About our facade sealing in Netley

Access is part of every facade job, and we plan it with you before quoting. Let us know what access exists or is planned, and any site rules we need to work around, so the price covers the real job. If you’re dealing with air leaks through failed facade joints and weathered joints at frame-to-structure perimeters, we can put it right. A specialist sealant contractor works differently from a general builder: on jobs in Netley, preparation and product choice get the time they need.

Building work in places the size of Netley is normally small-scale: a handful of new houses, barn conversions, a school or hall extension. Even a small site needs its perimeter and facade joints sized, backed and sealed properly.

Guaranteed is the last step of every job. You get a 12-month guarantee on our workmanship, and the quote explains what it covers.

Your questions answered

Can you work on a hospital site such as Hythe Hospital?

Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.

Will you take on work at estates like Ensign Way Business Park, close to 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.

Can you look at water coming in around a frame?

Yes. Photos are often enough to start, followed by a visit if needed. Failed perimeter sealant is a common cause, but not the only one, and we’ll be honest about which it is.

Is your workmanship covered by a guarantee?

Yes. The 12-month guarantee covers our preparation and application, but not damage, misuse or other trades’ work.

Can you handle several sites?

Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.

When is resealing likely to be due?

There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.

Can staff carry on working while you are here?

Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.

Contractors’ notes for Netley

The sea is no more than about 1 mile from Netley. On a coastal site, facade and perimeter joints face driven rain and, closer to the beach, salt, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. Netley sits in one of the drier corners of the country, the South East. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so the external programme keeps a little slack.

Hospital estates such as Hythe Hospital, 2.8 miles to the south-west of Netley, tend to grow and change in phases, often next to occupied wards, so facade and perimeter sealing has to fit the estates team’s plan. Further education sites such as Southampton City College Marine Skills Centre (to the north-west of Netley) are extended and refurbished from time to time, with mastic often programmed into the summer break.

Netley is about 3 miles north-east of Hythe, in Hampshire. We cover Netley and the rest of Hampshire, with the same fixed quotes and 12-month guarantee as everywhere else. Netley is one of 723 places we cover in Hampshire.

If you need facade sealing in SO31, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee. If your site is on Station Road, The Crescent and Hunt Avenue or close by, we can quote for facade joints. We also 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). Bigger towns within reach include 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).

Local landmarks in Netley

Around Netley, our work takes us to commercial buildings near 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. Other landmarks nearby include Bursledon Brickworks Industrial Museum (2.5 miles east) and Coldeast (2.8 miles east). Open spaces near Netley include Mercury Marshes.

Quoting for work in Netley

Quotes vary with the job. It mainly depends on:

  • Site requirements such as inductions and permits
  • Joint width, depth and condition
  • Access and working height
  • Quantities, in metres or numbers

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.

Sending details for a quote

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

  • The type of building and who uses it
  • The product your specification calls for
  • Photos of the joints, close up and from further back
  • Anything awkward about access or site hours

To get a fixed quote, phone 01277 525 020 or email us with the site address and an outline of the work. You can also send details through our quote form.

Common problems we fix in Netley

Adhesive failure, where the sealant peels away from one face, typically comes from poor preparation. Contamination, moisture or skipping the primer the maker specifies leave a weak bond.

What tends to prompt an enquiry:

  • Damp patches beside frames after rain
  • Weathered facade joints that have lost their grip
  • Sealant pulling away from frames or panels
  • Staining on stone next to old sealant

When a school such as Netley Abbey Infant School is extended or refurbished, the mastic package is often squeezed into the holidays.

What your quote should include

  • How they’ll work around occupants
  • What level of public liability insurance do they hold?
  • Will RAMS and insurance details be available?
  • The named product and why it was chosen

How to choose a sealant contractor

Keeping the joints sound

Once the work is signed off, a little attention goes a long way:

  • Brief window cleaners about newly sealed joints
  • Record the product and colour used on each elevation
  • Check the asbestos register before old mastic is disturbed
  • Avoid patch repairs on failed facade joints

Let the new sealant cure before washing the facade or windows near it. Keep high-pressure jets and strong chemicals away from new sealant and tell your cleaning contractor.

Get the joint design right when resealing: the right width, backing rod and a sealant with enough movement capability. Repeating a faulty detail just repeats the failure.

How a job runs

A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work normally takes anything from a single day to several weeks, depending on joint lengths, access and the weather, and our waste is bagged and taken away as we go. For a job in Netley, 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. Access, site rules and timing are settled with the client up front.
  2. Weather and temperature are checked against the product’s limits.
  3. We remove the old bead and check the edges are sound.
  4. Joints are cleaned, primed if required and fitted with backing rod.
  5. Facade-grade sealant goes in and is tooled to a tidy concave profile.
  6. Once signed off, the work carries our 12-month guarantee.

Before we start on site

  • Have the specification and drawings to hand
  • Flag any permit to work we will need
  • Point out any areas we must not close

Request a quote

Every quote starts with the facts: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we will arrange a site visit if anything is unclear.

Advice

When it isn’t the sealant

We check first that sealant really is the fix. It won’t put right:

  • Arranging specialist high-level access, which is planned with the client
  • Render or concrete edges that have broken away
  • Damp caused by condensation inside the building

Not sure which it is? You can give us a call on 01277 525 020 or send details through our quote form and we’ll tell you honestly before you book.

What we seal

  • Perimeter joints where frames meet the structure
  • Coping and flashing joints
  • Cladding panel joints
  • Window and door perimeters
  • Stone and brick facade joints
  • Shopfront frames

Different surfaces, different methods

Cladding panel joints

Where panels are sealed rather than open-jointed, the bead is part of the weather line. We cut out failed joints along their full length and rebuild them with backing and a facade-grade sealant.

Window and door perimeters

Perimeter joints move as frames expand and contract in the sun. Rod placed at the right depth lets the bead stretch without tearing.
