Facade sealing for commercial buildings in Norton Green

Installing framed glazing systems isn’t part of our work. What we seal are the joints around them: the frame-to-structure perimeter, panel-to-panel joints and window and door surrounds. Most enquiries involve failed seals around shopfront and entrance frames and cold air coming in at window perimeters, across perimeter joints where frames meet the structure, stone and brick facade joints and window and door perimeters. One point of contact handles commercial sealant work in Norton Green from the first photos to the final walk-round, whether it’s one building or several.

Construction in and around smaller places such as Norton Green is often barn conversions, small groups of houses or extensions to halls and schools. Each still needs a proper mastic package: window perimeters, facade joints and internal sealant to the specification.

Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If a joint we sealed fails because of how it was installed, we come back and put it right.

When something else is needed

A few problems need another trade or a different fix, and we say so rather than covering them up:

  • Damaged frames that need replacing
  • Water getting in through cracked render or porous masonry
  • Providing access systems for the work

Not sure which it is? You can ring 01277 525 020 or email us and we’ll tell you honestly.

What we seal

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

How the job changes by surface

Brick and stone facades

Brick and stone facades have perimeter and movement joints that need a compatible sealant. Neutral-cure products are used because acetoxy types can mark some stone, and primers go on where specified.

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.

Facade sealing in Norton Green: the local picture

With the shore within about 1 mile, Norton Green counts as a coastal location. Coastal exposure means perimeter and cladding joints work harder than on an inland job, so we check the specified product suits the exposure before the first bead. Norton Green 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 external mastic is timed for workable conditions and agreed with the site manager.

Projects at schools like All Saints Church of England Primary School work to term dates, so mastic is programmed tightly. Work at a hotel such as The George Hotel, 1.2 miles to the north-east of Norton Green, tends to be programmed around bookings, mastic included. With historic properties like Mottistone Manor (4.9 miles south-east of Norton Green) in the area, refurbishment work often meets old masonry that needs compatible sealants.

Norton Green is about 5 miles south of Lymington, in the Isle of Wight. Our applicators travel to Norton Green for work on facade joints. Our the Isle of Wight coverage takes in 125 places. There’s a separate page for Southampton, about 16 miles away.

We also cover Freshwater (1 mile south), Colwell (1 mile south-west), Easton (1 mile south), Totland (1 mile south-west) and Afton (1 mile south).

Diagnose, treat, sign off

Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work typically takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather, and our waste is bagged and taken away as we go. If others near Norton Green need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.

  1. First we review photos, drawings or what we saw on a visit, and agree how each joint will be reached.
  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. The completed runs are checked with you, then the 12-month guarantee applies.

Advice

How the quote is worked out

Each job is priced on its own details. The main factors are:

  • Location, for remote and island sites
  • Whether old sealant has to be cut out first
  • The size and state of each joint
  • Working within restricted access windows

Access often affects the price as much as the sealing: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Before you send an enquiry

To price the job accurately, we need to understand the site. Useful things to include:

  • Specification clauses that apply
  • The asbestos register, for older buildings
  • Where the site is, with the postcode
  • Rough lengths or quantities, or drawings if you have them

Every job follows the same four steps: send details, get a quote, we seal, guaranteed. To take the first step, ring 01277 525 020 or email a schedule or drawings.

For managing agents and facilities managers

Building owners and managing agents use us on sealant work across single buildings or whole portfolios. Several sites can go on one quote, so there’s one set of paperwork to deal with.

We take on planned maintenance as well as one-off repairs: working through a building or an estate in stages that fit your budget. Norton Green can form part of a wider programme.

After the work

Regular inspection catches problems early. In particular:

  • Check that rainwater leaves the facade the way it was designed to
  • Never let anyone seal over old sealant
  • Check the asbestos register before old mastic is disturbed
  • Note when each elevation was last resealed

Let the new sealant cure before washing the facade or windows near it. Pressure washers and harsh cleaners can damage a fresh bead, so brief your window cleaners.

Check older buildings for asbestos before disturbing old mastic. Older sealants can contain asbestos, and if it’s suspected, we stop until it has been tested.

FAQs: Norton Green

Is Norton Green too far out for you?

No. Small places get the same service as large ones. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.

Is hospital work, at somewhere like Lymington New Forest Hospital, something you do?

Yes, hospitals are one of the sectors we cover. Each area is agreed with the ward or department and the estates team in advance.

How much does the work cost?

That depends on the job: the volume of work, the access, the specified product and how it’s phased. Call for a fixed quote and we’ll price it properly.

Are you CHAS accredited?

Yes. Mastic Doctor is CHAS accredited and a Constructionline member.

Do you replace failed glazing units?

No. A glazing contractor handles that. What we seal are the joints around frames and panels across the facade.

How soon can the area be used again?

We will confirm how long the chosen product needs to cure, and sign any area that should be left alone.

Do you seal on top of existing sealant?

No, never. Sealing over old material is one of the classic causes of early joint failure, so it all comes out first.
