Facade sealing in Borehamwood
Tell us what needs sealing and where, with photos or drawings if you have them, and we’ll price it.
Surface by surface
Brick and stone facades
Brick and stone facades have perimeter and movement joints that need a compatible sealant. We avoid acetoxy silicone, which can stain some natural stone, with primer where its maker specifies.
Precast concrete panels
Joints between precast panels carry real movement. A sealant of the right movement class goes in over backing rod with primer where the product requires it.
Facade sealing in Borehamwood, done properly
Our facade sealing work covers external facade joints, window and door perimeters, cladding panel joints and the perimeter joints where frames meet the structure. Coping and flashing joints are included where sealant is the specified fix. Site teams most often ask us about gaps between rainscreen or cladding panels and damp patches beside frames after rain, across perimeter joints where frames meet the structure, stone and brick facade joints and shopfront frames. Most enquiries from Borehamwood start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
Construction in a town such as Borehamwood is often smaller schemes: a few new flats, a school extension, a refurbished unit. A mastic package on a smaller site still needs the same care at window perimeters and facade joints.
Whoever the client is, the cover is the same: a 12-month guarantee on our workmanship. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Sites and facades in and around Borehamwood
Rainfall across the South East, Borehamwood included, is lower than in many parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, which is why external dates are agreed with the site manager. There are a number of hotels within about 2 miles of Borehamwood. Hotel schemes tend to have fixed reopening dates, so the mastic is programmed tightly with the other trades.
For contractors on a campus like Middlesex University, 4.7 miles south of Borehamwood, facade and perimeter sealing has to fit around students and term dates. When a school such as St Teresa Catholic Primary School is extended or refurbished, the mastic package is often squeezed into the holidays. Older buildings in the area around Borehamwood, such as Wyllyotts Manor, 4.3 miles to the north-east of Borehamwood, need care when sealed: the product has to suit soft or historic materials.
Borehamwood is about 5 miles east of Watford, in Hertfordshire. We cover Borehamwood, with the same fixed quotes and 12-month guarantee as everywhere else. Borehamwood is one of 371 places we cover in Hertfordshire. Our London page has more on work in that area (14 miles or so).

Local landmarks in Borehamwood
Locally, jobs take us to sites close to Aldenham Country Park, The Pick & Shovel pub and Yavneh College and the streets around them. The nearest railway station is Elstree & Borehamwood station, roughly 0.6 miles south-west of the centre. A little further out are Royal National Orthopaedic Hospital (2.4 miles south-west) and Spires Shopping Centre (3.1 miles east). For a walk, there’s Darland's Lake and Rowley Lodge Field.
Cost factors for facade joints
Before we quote, we look at:
- Specialist products, such as fire-rated or hygienic sealants
- Backing rod, priming and other preparation
- Access and working height
- Whether old sealant has to be cut out first
The product called for affects the cost, as does the preparation each joint needs, from cutting out to priming and backing rod. Access, phasing and site rules also count.
Before you send an enquiry
It doesn’t need to be a full survey. A few details are enough to get going:
- Where the site is, with the postcode
- Clear photos of the problem areas
- Drawings or a marked-up plan, if available
- The asbestos register, for older buildings
A handful of photographs and a postcode is the fastest way to a quote. Upload them with the quote form, or call the office on 01277 525 020 or use the quote form to discuss it first.
When it isn’t the sealant
Part of a good diagnosis is knowing where sealant stops. We’ll tell you if the real problem is any of the following:
- Cracked or spalling substrates that need repair before sealing
- Specialist high-level access methods
- Installing or repairing glazing systems
Not sure which it is? You can call 01277 525 020 or email a schedule or drawings and we will tell you honestly.
What we seal
- Perimeter joints where frames meet the structure
- Window and door perimeters
- Coping and flashing joints
- Stone and brick facade joints
- Cladding panel joints
- Shopfront frames
Aftercare for building managers
Every sealant joint needs some looking after, and their life depends on movement, exposure, cleaning and use. We suggest:
- Check the asbestos register before old mastic is disturbed
- Keep sills, gutters and drainage paths clear
- Add perimeter sealant to planned maintenance checks
- Don’t wait for a second leak before calling
Let the new sealant cure before washing the facade or windows near it. Pressure washers and harsh cleaners can damage a fresh bead and tell your cleaning contractor.
Deal with sections that fail early as soon as they show. Small repairs stop small leaks becoming large ones.
Borehamwood: questions and answers
Can you work around term dates at a campus such as Middlesex University?
Yes. Tell us the term dates, vacation periods and access windows, and we’ll plan the work around them. Let us know which documents your site asks for, and we’ll confirm them alongside the quote.
Can you work at a site such as Borehamwood Shopping Park, by Borehamwood?
Yes. Our area takes in Borehamwood and its surroundings, with estates and business parks such as Borehamwood Shopping Park included. To start, just give us a call on 01277 525 020 or use the quote form with the unit, the joints involved and your access times.
Do you need to see the site first?
Photos, drawings or a schedule are often enough to quote. Where they aren’t, we arrange a site visit before quoting.
How do you choose the sealant?
The specification comes first, if there is one. Without one, the joint decides: its movement, its surfaces and what it has to cope with.
Can weather delay the job?
For external joints, yes. The joint has to be dry and within the product’s temperature range, so frost, rain or cold mornings can delay outside work. Internal work is rarely affected.
Which sealant do you use on facades?
It depends on the joint, the substrate and any specification. Specifications often refer to BS EN 15651-1 for facade sealants or BS EN 15651-2 for glazing.
How is access to upper-level joints handled?
We agree access with the client at the start. Let us know what access is in place or planned, and the quote will reflect it.

How a job runs
The first thing on site is a walk round with your contact, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. In a town such as Borehamwood, most jobs are single buildings. Your photos, drawings or a site visit come first, followed by a fixed quote.

- Product choice follows the joint’s movement and substrate.
- The existing bead comes out in full and the joint faces cleaned.
- Primer is applied where the maker specifies it.
- Backing rod is fitted and the new sealant gunned in and tooled.
- We go over the completed work with you before leaving.
What we need from you
- Tell us your opening times and when work is allowed
- Point out any areas we must not close
- Tell us what induction or permit system the site runs
Getting a fixed quote
Specifications, drawings and tender packages are welcome with any enquiry, and we’ll price against exactly what is specified. Smaller jobs need nothing more than photos and a few notes.

Should maintenance staff do it?
There’s also the paperwork. Main contractors and clients often ask for CSCS cards, RAMS and insurance details, and our CSCS-carded applicators are used to working under those rules.
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
