About our facade sealing in Ridge

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, and we will fit the work around it. If you have discoloured or dirty facade joints and hard, chalky sealant that no longer flexes, we can help, on cladding panel joints, stone and brick facade joints and perimeter joints where frames meet the structure alike. Looking for mastic applicators who cover Ridge? We have been sealing commercial buildings since 2005, with CSCS-carded applicators.

Sites around smaller places like Ridge can be a fair drive from suppliers, so we come with everything the package needs. Drawings, photos and the programme let us give a fixed quote.

Our 12-month guarantee is about workmanship, not wear and tear. How long a sealant joint lasts depends on movement, exposure, cleaning and use, so we spell out the cover before we begin.

For managing agents and facilities managers

Whether you’re a managing agent, a property factor or an owner’s representative: send the details, accept a fixed quote, and we carry out and guarantee the work. Keys, access and contacts can be agreed in advance.

Planned maintenance programmes are welcome: resealing failed joints building by building, on a schedule that suits your budget. Ridge can form part of a wider programme across Hertfordshire.

On site: what to expect

Occupied buildings need a little choreography. We sign and contain the area we’re in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. Jobs in and around smaller places like Ridge are usually planned as a single visit, so photographs and measurements up front really help. Then the right materials arrive with us.

  1. We look at the joints, the drawings and the access before pricing.
  2. Failed sealant is cut out along its full length.
  3. Both faces are cleaned and, where the product needs it, primed.
  4. Closed-cell rod fixes the depth, and the sealant grips two sides only.
  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.

Getting the site ready

  • Share the asbestos register for older buildings
  • Point out any areas we must not close
  • Have the specification and drawings to hand

Ask for a quote

Honest limits

A proper diagnosis includes knowing what sealant can’t do. You will hear from us if the cause turns out to be any of the following:

  • Joints too narrow for the movement they take, which need redesign
  • Work on the window or framing system itself
  • Damp caused by condensation inside the building

If you’re not sure, just phone 01277 525 020 or email a schedule or drawings and we’ll give you a straight answer before you book.

What we seal

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

Cost factors for facade joints

Your fixed quote is built from the real scope. It takes account of:

  • Any access equipment needed
  • The total length or number of joints
  • Working within restricted access windows
  • Removal of failed or old sealant

Access can matter as much as the joints themselves: easy-to-reach joints are quicker than those that need equipment to get to. Mention the access as part of your enquiry.

Details that help us quote

The more we know, the firmer the quote. Helpful details to send:

  • A wide shot and a close-up of the area
  • Your programme or deadline
  • Specification clauses that apply
  • The site address and postcode

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

Signs you need facade sealing in Ridge

Three-sided adhesion is a classic installation fault. Without rod or bond-breaker tape, the bead is held back and tears as the joint moves.

Most enquiries start with one or more of the following:

  • Weathered facade joints that have lost their grip
  • Failed sealant on precast panel joints
  • Leaks at window and door perimeters
  • Failed seals around shopfront and entrance frames

Projects at schools like St Giles' CofE Primary School work to term dates, so mastic is programmed tightly.

Questions to ask before you book

  • Whether old or failed sealant will be cut out, not overlaid
  • The terms of the workmanship guarantee
  • Can the work be phased to keep areas open?
  • Is depth set with backing rod, or bond-breaker tape in shallow joints?

Questions to ask before you appoint anyone

Building and refurbishing in Ridge

Central London is about 15 miles from Ridge. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and main contractors there need mastic that keeps to the programme. A 2-mile radius around Ridge takes in several hotels. Hotel extensions and refits normally have to fit around bookings, so mastic dates are tight.

With historic properties like Wyllyotts Manor (to the east of Ridge) in the area, refurbishment work often meets old masonry that needs compatible sealants. When units on a site such as Borehamwood Industrial Park (to the south of Ridge) are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.

Ridge is about 2 miles north-east of Borehamwood, in Hertfordshire. Looking for facade sealing in Ridge? We can help, as we do across Hertfordshire. We work across 371 places in Hertfordshire, from busy centres to rural villages. We also cover London, some 15 miles away.

Green spaces nearby include Darland's Lake and Furzefield Wood and Lower Halfpenny.

Why deal with it now?

Failed joints let in more than water: draughts around frames add to heating costs and complaints. A new seal closes the gap for both. Converted and older buildings near places like Ridge tend to move, and aged sealant cracks. The right product, sized to the joint, copes much better.

Quantities, awkward access and phased working all shape the price. Site requirements like inductions and permits play a part as well.

Is Ridge too far out for you?

Not at all. Ridge is within our area. London and every South East county are within our area. Send photographs and a list of what needs doing, and we will plan the job to need as few trips as possible.

Is any job too small?

Single areas, one-off repairs and whole buildings are all quoted the same way: send details, get a fixed quote, we seal, guaranteed.

What hours do you work?

We are in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.

How do we ask for a quote?

There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.

Do you need to see the site first?

Many jobs can be quoted from photos, drawings or a joint schedule. Where they aren’t, we arrange a site visit.

Can you look at water coming in around a frame?

Yes. We look at the perimeter sealant and tell you whether it has failed as part of pricing. If the water seems to come from a roof, sill or the glazing unit instead, we say so.
