Facade sealing in Brookmans Park, done properly
Most facade joint failures trace back to the joint, not just the sealant. Joint width needs to match how far the joint moves and how far the sealant can stretch, and closed-cell rod sets the depth, keeping the bond to two faces. We work on perimeter joints where frames meet the structure, shopfront frames and cladding panel joints, and the failures we are asked to look at most are old perimeter mastic that has dried out and perimeter sealant that has split or peeled away. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, in Brookmans Park it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Sites around smaller places like Brookmans Park can be a fair drive from suppliers, so we come with everything the package needs. Send drawings or photos and the programme and we will quote to suit.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Facades, frames and programmes in Brookmans Park
Brookmans Park sits in one of the drier corners of the country, the South East. Even so, frost and condensation on steel and glass are common on winter mornings, so the external programme keeps a little slack. Brookmans Park lies roughly 16 miles out from central London. 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.
Historic houses such as Wyllyotts Manor, 1.8 miles south of Brookmans Park, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products. School extensions, at buildings such as Chancellor's School, usually run to the summer holidays, mastic included. Building work at universities like University of Hertfordshire, 2.8 miles to the north of Brookmans Park, is often timed for the summer, mastic included.

FAQs: Brookmans Park
Will you take on work at estates like Devonshire Business Centre, close to Brookmans Park?
Yes, sites like Devonshire Business Centre are within our area, along with the rest of Brookmans Park. A few photos and the unit address let us price the work.
Can you work around term dates at a campus such as University of Hertfordshire?
Yes, holiday working periods are the norm on campus jobs. Tell us which site documents you need, such as RAMS, our insurance certificate or CSCS details, and they’re confirmed with the quote.
Can you handle several sites?
Yes. A group of buildings can go on one quote, with one point of contact.
Do you use silicone for external joints?
Low-modulus, neutral-cure silicone suits many facade and perimeter joints. Hybrid or MS polymer, polyurethane and polysulphide sealants suit others, depending on the substrate and the specification.
Will your applicators have CSCS cards?
Yes. If you need card details for site access, let us know and we will send them with the quote.
Do you replace windows or glass?
No. A glazing contractor handles that. We reseal window perimeters, panel joints and frame-to-structure perimeters across the facade.
Can you work on upper floors?
Access is planned with you before we quote. Tell us about access: existing scaffold, what you are arranging and any site restrictions.
What happens if it’s left?
Topping up a failed joint normally buys very little time. A full cut-out and fresh bead is the repair that holds. Around Brookmans Park, it’s better to renew all the failing joints at once, rather than one at a time. Send photographs of each area and we will quote for the lot.
Small jobs and large programmes are priced from the same things: what’s in scope, how we reach it, what’s specified and when it needs doing. Call for a quote, and you’ll have a fixed figure to work with.

Surface by surface
Brick and stone facades
Joints in natural stone need care to avoid staining. We use a product suitable for the stone where the specification names one.
Render and coated surfaces
Paintable sealants exist for joints that will be coated. We confirm the product with you before starting.
Our process
Our CSCS-carded applicators arrive with the sealants, primers and backing rod the job calls for. Any old material is cut back to clean, sound faces, the manufacturer’s primer is applied where it’s called for, and each bead is tooled to a neat concave finish. If others near Brookmans Park need work, visits can be combined, which keeps travel down. A fixed quote is given before anything starts.
- First we review photos, drawings or what we saw on a visit, and agree how each joint will be reached.
- Failed sealant is cut out along its full length.
- Both faces are cleaned and, where the product needs it, primed.
- Closed-cell rod fixes the depth, and the sealant grips two sides only.
- The new sealant goes in and is tooled firmly onto both faces.
- The completed runs are checked with you, then the 12-month guarantee applies.
Before we start on site
- Send asbestos survey details if the building is pre-2000
- Warn occupants and staff about the work
- Tell us what induction or permit system the site runs

Related advice
Should maintenance staff do it?
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we’ll confirm the paperwork you need with the quote.
Site maintenance staff can often handle a short internal joint. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Keeping the joints sound
Your facilities or cleaning team can help the joints last. Pass these on to them:
- Report water ingress at frames as soon as it shows
- Keep sills, gutters and drainage paths clear
- Add perimeter sealant to planned maintenance checks
- Plan facade sealing alongside redecoration
If new signage, brackets or services are fixed through a sealed joint, the seal needs making good. Make sure the joint is resealed afterwards with a compatible product.
Check older buildings for asbestos before disturbing old mastic. Older sealants can contain asbestos.
