About our facade sealing in Swanwick

Some clients need every window on a block resealed; others need a few leaking frames sorted. The approach doesn’t change with the size: old sealant out, faces cleaned, depth set and a new bead tooled in. A 12-month guarantee applies to our workmanship. The enquiries we see most involve discoloured or dirty facade joints and perimeter sealant that has split or peeled away, on window and door perimeters, shopfront frames and coping and flashing joints. Looking for mastic applicators who cover Swanwick? We have been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.

For a site near Swanwick, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Send drawings or photos and the programme and we’ll quote to suit.

We sign every job off with a 12-month guarantee. The promise is simple: if the work we did fails within twelve months, we return to fix it.

On site: what to expect

We schedule the visit to fit the site hours and access windows you give us. While we are working, the area stays contained and tidy, and your contact hears from us before we move to the next area. Rural sites near Swanwick may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.

  1. We plan access and the order of elevations with the client.
  2. We only seal when joints are dry and within the product’s temperature range.
  3. We remove the old bead and check the edges are sound.
  4. Faces are cleaned, primed where needed and backed.
  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.

What we need from you

  • Share the asbestos register for older buildings
  • Clear stock, furniture or equipment away from the joints
  • Point out parking and an unloading spot

Facade sealing in Swanwick: the local picture

Swanwick lies within about 3 miles of the sea. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, which puts weight on correct joint sizing, priming and a sealant suited to the exposure. Swanwick has a number of hotels close by, all within 2 miles. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.

School extensions, at buildings such as Sarisbury Church of England Junior School, usually run to the summer holidays, mastic included. For a contractor working at a hospital such as Fareham Community Hospital, which lies south-east of Swanwick, perimeter and facade sealing is planned around patients and deliveries. Recladding or extending a unit at a site like Park Gate Business Centre (to the south-east of Swanwick) brings panel joints and frame perimeters into the programme.

Swanwick is about 2 miles south of Hedge End, in Hampshire. Across the SO31 postcode area, it works the same way: details in, fixed quote out, then sealing and a 12-month guarantee. Swanwick is one of 723 places in Hampshire on our list.

We take on facade joints across the SO31 and PO15 postcode area, whatever the building. If your site is on Walpole Lane, Ashby Mews and Swanwick Lane or close by, send details and we’ll quote for facade joints. We also cover Lower Swanwick (1 mile north-west), Sarisbury (1 mile south-east), Park Gate (1 mile south-east), Burridge (1 mile north-east) and Sarisbury Green (1 mile south) for facade joints. Nearby towns on our patch include Winchester (12 miles north), Gosport (8 miles south-east), Havant (13 miles east), Eastleigh (6 miles north-west), Fareham (4 miles south-east) and Horndean (12 miles east).

Building owners, agents and FMs in Swanwick

Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, with each stage agreed with your site contact.

Main contractors use us as their sealant subcontractor on new-build and refurbishment projects. Programme, specification and site rules come first.

What we can’t put right

Not every problem is a sealant problem, and we’d rather tell you before you spend money. These need a different solution:

  • Movement beyond what any sealant can handle
  • Replacing glass or failed glazing units
  • Damaged frames that need replacing

If you are not sure, just call 01277 525 020 or use the quote form and we’ll give you a straight answer before you book.

Where we work in Swanwick

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

What the job involves on each surface

Window and door perimeters

Frame materials vary, and so does the preparation. Primer goes on where the manufacturer specifies it for that substrate.

Coping and flashing joints

Where the specification calls for sealant at copings or flashings, we can seal them. These joints take full exposure to weather, so preparation and product choice matter.

Questions we’re asked in Swanwick

Is Swanwick too far out for you?

Not at all. Swanwick is within our area. We cover Greater London and the counties of the South East. We plan jobs in smaller places so return trips are kept to a minimum.

Does your area include sites such as Park Gate Business Centre, near Swanwick?

Yes. We cover Swanwick and the area around it, including industrial estates, business parks and retail parks such as Park Gate Business Centre. To start, just ring 01277 525 020 or send photos by email with the unit, the joints involved and your access times.

Will you come and look before quoting?

Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit.

When is resealing likely to be due?

There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.

Can you fit around our working hours?

The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.

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. Indoors, the weather is rarely a problem.

What type of sealant goes on window perimeters?

Most facade and window perimeter joints take a low-modulus neutral-cure silicone. Some joints call for hybrid, PU or polysulphide instead.

Keeping the joints sound

Your facilities or cleaning team can help the joints last. Pass these on to them:

  • Keep sills, gutters and drainage paths clear
  • Investigate damp beside windows promptly
  • Insist on a full cut-out when joints are renewed
  • Add perimeter sealant to planned maintenance checks

Record the sealant type and date on the building file. Future work can then match the product and colour across the elevation.

Don’t wait for a full elevation to fail. Small repairs stop small leaks becoming large ones behind the facade.

Why deal with it now?

The longer a failed joint is left, the more the substrate suffers: edges get wet, render and timber deteriorate and frames can move. Early action keeps it simple. One visit to deal with every failing joint makes more sense than several trips to a place like Swanwick. Photos of every joint help us quote for the whole job.

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