Facade sealing in West Town

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

What we’re called out for in West Town

The wrong product causes its share of trouble: acetoxy-cure silicone may mark stone or corrode certain metals, and an interior product won’t last outdoors. Neutral-cure, facade-grade products are what most external joints need.

If one of these sounds familiar, it’s time for a closer look:

  • Air leaks through failed facade joints
  • Cladding panel joints that have opened up
  • Perimeter joints where frames meet the structure
  • Perimeter sealant that has split or peeled away

For a contractor working at a hospital such as St James Hospital (2.6 miles west of West Town), perimeter and facade sealing is planned around patients and deliveries.

What your quote should include

  • How joint depth will be controlled
  • Can the work be phased to keep areas open?
  • What level of public liability insurance do they hold?
  • How the joint faces will be prepared and primed

Our contractor checklist

About our facade sealing in West Town

External joints face UV, rain, temperature swings and building movement all year, and they wear out over time. Life depends on movement, weathering, product choice and the quality of the original work. When it fails, the whole bead is cut away and the joint rebuilt. If you are dealing with weathered facade joints that have lost their grip and perimeter sealant that has split or peeled away, we can put it right, whatever the surface. For commercial sealant work in West Town, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.

For a contractor on a smaller site near West Town, one mastic visit at the right stage saves return trips. Let us know the key stages and we’ll time the work so nothing waits on us.

Every job ends the same way: guaranteed. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

How the quote is worked out

These are the things that shape the price:

  • The total length or number of joints
  • The size and state of each joint
  • Phasing around occupants
  • The product specified

Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote.

Before you send an enquiry

To price the job accurately, we need a clear picture of the site. Send us:

  • When you need the work done
  • Any specification or named product
  • Asbestos survey details if the building is older
  • How the joints are reached, and at what height

Every quote starts with the facts: the joints involved, quantities, access and the product called for. Send what you have, and we’ll arrange a site visit if anything is unclear.

Should maintenance staff do it?

What you see is the finished bead, but most of the work is hidden. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Paperwork matters too. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and we will confirm the paperwork you need with the quote.

How a job runs

At the end of each section, we remove the tape, clean down and inspect every joint. If an area should be left alone while the sealant cures, we say how long and put signs out. For a site in West Town, we plan so the whole job is done in one go where possible. Clear photographs and measurements help us bring the right products.

  1. Access, site rules and timing are settled with the client up front.
  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. We hand over with our 12-month workmanship guarantee.

What we need from you

  • Move anything stored against the joints
  • Arrange parking or a loading space
  • Let us know about inductions and permits

Getting a fixed quote

Specifications, drawings and tender packages are welcome with any enquiry, and we will price the work to it. For smaller jobs, photos and a description will do.

Advice

New build and refits around West Town

West Town is within about 1 mile of the coast. 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. Central London is about 62 miles from West Town. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, so mastic packages have to keep pace with busy programmes.

When a college such as Portsmouth College (to the north-west of West Town) builds or refurbishes, the mastic package usually has to fit around students and staff. University estates such as University of Portsmouth - Langstone Campus (to the west of West Town) tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal.

West Town is about 1 mile west of South Hayling, in Hampshire. We cover commercial sites throughout West Town, whether it’s a single job or part of a planned programme. Across Hampshire, 723 places are covered, including West Town.

We take on facade joints across the PO11 postcode area, for business premises of every kind. For a building on West Lane, Beach Road and Bacon Lane or nearby, we can quote for facade joints.

Why it’s worth doing now in West Town

Failed joints let in more than water: occupants notice draughts and cold spots around windows. A new seal closes the gap for both. For buildings in places like West Town, one well-planned visit beats several small ones, so we’d suggest renewing all the joints that are going, not just the worst.

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Tell us how the joints are reached and call for a quote.

Why appoint us

  • Fixed quotes based on photographs, drawings or a visit
  • A range of standard colours, depending on the product
  • CHAS accredited contractor
  • Workmanship guaranteed for 12 months

West Town: questions and answers

Will you plan work around the academic year at somewhere like University of Portsmouth - Langstone Campus?

Yes. Education sites normally want the work in vacations or in phases during term, and we plan to suit. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.

Does the sea air around West Town change the choice of sealant?

It can. Coastal exposure works external joints harder than inland weather. We check the specified product suits the exposure and pay close attention to preparation.

How soon can the area be used again?

The product and site conditions decide that. Some take light use quickly, others need longer to cure, and we confirm it before leaving site.

Will rain stop the work?

Year-round work is possible as long as joints are dry and temperatures suit the product. Cold, damp mornings can delay a start.

Are you CHAS accredited?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member, which helps with supplier vetting.

Can you handle several sites?

Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.

Can the sealant be colour-matched?

It depends on the product specified. Some ranges offer many colours, others very few, so the available colours are confirmed with the quote.

What sealant work can’t fix

Being straight saves everyone time. Fresh joints won’t solve:

  • Damaged frames that need replacing
  • Water getting in through cracked render or porous masonry
  • Joints too narrow for the movement they take, which need redesign

Not sure which it is? You can give us a call on 01277 525 020 or send photos by email and we’ll tell you honestly.
