Need facade sealing in Wellow?

Photos, a specification or a quick description of the joints is enough to start a fixed quote.

How a job runs

Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Joint faces are cleaned back to sound, dry surfaces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. Jobs in and around smaller places like Wellow are normally planned as a single visit, so we ask for photos and rough sizes first. Then the right materials arrive with us.

  1. We look at the joints, the drawings and the access before pricing.
  2. The old bead is cut away completely, not overlaid.
  3. Both faces are cleaned and, where the product needs it, primed.
  4. Backing rod, or bond-breaker tape in shallow joints, limits the depth.
  5. A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
  6. We walk the finished joints with you before handing over.

Preparing the site

  • Explain the parking and delivery arrangements
  • Send your site hours and access windows
  • Tell us which areas need to stay in use

Facade sealing in Wellow, done properly

Most facade joint failures trace back to the joint, not just the sealant. The width has to suit the expected movement and the sealant’s movement capability, and closed-cell rod sets the depth, keeping the bond to two faces with the ratio the sealant maker recommends, often around 2:1. We work on cladding panel joints, window and door perimeters and coping and flashing joints, and what we’re called in for most is perimeter joints where frames meet the structure and perimeter sealant that has split or peeled away. One point of contact handles commercial sealant work in Wellow from the first photos to the final walk-round, whether it’s one building or several.

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

Every job we finish is backed by a 12-month workmanship guarantee, in Wellow as everywhere else we work. If our installation lets you down in that time, we return and fix it.

Sites and facades in and around Wellow

With the shore within about 2 miles, Wellow counts as a coastal location. Schemes this close to the sea see their facade joints tested by wind and rain from the day they’re sealed, and the sealant, primer and backing need choosing with that in mind. The South East is one of the drier parts of the UK. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, which is why external dates are agreed with the site manager.

With historic properties like Mottistone Manor (2.8 miles south of Wellow) in the area, refurbishment work often meets old masonry that needs compatible sealants.

Wellow is about 6 miles south-east of Lymington, in the Isle of Wight. Our applicators travel to Wellow for work on facade joints. 125 places across the Isle of Wight fall within our area, Wellow among them. There’s a separate page for Southampton, about 16 miles away.

If you need facade sealing in PO41, the process matches everywhere else we work: details, then a fixed price, then sealing and a 12-month guarantee. Close to Wellow, our area also takes in Thorley Street (1 mile north-west), Ningwood (1 mile east), Thorley (1 mile north-west), Newbridge (1 mile east) and Shalcombe (1 mile south). A short drive away, we cover Newport (7 miles east), Ryde (13 miles east), Cowes (8 miles north-east), Sandown (13 miles east), Shanklin (13 miles east) and Ventnor (12 miles south-east). For island and remote sites, travel and materials need planning ahead.

Wellow: questions and answers

Can you work to our programme on a site in or near Wellow?

Yes, we work to the programme and the sequence the site sets. We are CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.

Is a smaller place like Wellow outside your area?

No. Small places get the same service as large ones. We work across Greater London and the South East. Where we can, we group nearby jobs to make the most of each trip.

How many days will you need on site?

That varies with the scale of the job, though a typical visit normally takes anything from a single day to several weeks, depending on joint lengths, access and the weather. Larger or phased jobs take longer, and we’ll give you a timescale with the quote.

Does the weather affect the work?

Outside, yes. The joint has to be dry and within the product’s temperature range, so damp, frosty or very cold days can stop external work. Internal work is rarely affected.

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 tell you which.

How is access to upper-level joints handled?

That comes down to the access arranged for the job. When you speak to us on 01277 525 020 or use the quote form, describe the access, and we will agree the approach together.

Can you send site paperwork?

Let us know which documents the site needs, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm them with the quote.

Cost factors for facade joints

Quotes vary with the job. It mainly depends on:

  • Removal of failed or old sealant
  • Induction, permit and paperwork requirements
  • Location, for remote and island sites
  • Working within restricted access windows

No two sites price the same: the joint sizes, the specified product, access and working hours each have a bearing. A fixed quote follows once we understand the job.

Sending details for a quote

A few photos plus some basic facts will normally do. Please tell us:

  • Rough lengths or quantities, or drawings if you have them
  • A wide shot and a close-up of the area
  • Your programme or deadline
  • What the building is and how it’s used

The quickest route to a quote is a few photographs and the site postcode. Upload them with the quote form, or call 01277 525 020 or send photos by email if you’d rather talk the job through.

General trades versus a specialist

Certain joints really need a specialist: for example fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.

The visible bead is only part of the job. Correct depth, the right primer and a sealant matched to the movement are where general trades tend to cut corners.

Do you need facade sealing in Wellow?

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. Most external joints call for a neutral-cure, facade-grade sealant.

Things that normally lead to an enquiry:

  • Facade joints cracked through the middle
  • Draughts around frames and panels
  • Old perimeter mastic that has dried out
  • Staining on stone next to old sealant

When a school such as Shalfleet Church of England Primary School is extended or refurbished, the mastic package is often squeezed into the holidays.

Questions to ask before you book

  • Whether primer will be used where the manufacturer specifies it
  • Their public liability cover
  • Will failed sealant be removed rather than covered?
  • What the guarantee covers, and for how long

Questions to ask before you appoint anyone

For managing agents and facilities managers

As a CHAS accredited contractor and Constructionline member, we make supplier vetting simple. We are fully insured, and our insurance certificate can go with the quote.

Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, with each stage agreed with your site contact.

Surface by surface

Window and door perimeters

Frames grow and shrink with temperature, and the perimeter joint has to follow. Rod placed at the right depth lets the bead stretch without tearing.

Render and coated surfaces

Where the joint will be painted over, a paintable hybrid or PU sealant may suit. The choice depends on the specification and finish.
