Hospitality, education, healthcare, office and retail clients book us directly too. We plan around the way the building is used, so guests, pupils, patients or staff are disturbed as little as possible.
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
How we handle facade sealing in Redbourn
Water ingress at window frames is a frequent reason facilities managers contact us. Failed perimeter sealant is a frequent cause. If the evidence points away from the sealant, we say so before quoting. We work on cladding panel joints, perimeter joints where frames meet the structure and coping and flashing joints, and what we’re called in for most is failed seals around shopfront and entrance frames and new sealant peeling off old mastic. Facilities teams, main contractors and managing agents in Redbourn tend to want the same three things: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
On a small site around Redbourn, the mastic is best done in the fewest visits we can manage. Tell us when scaffold comes down and when decoration finishes, and we’ll plan around those stages.
The 12-month guarantee is for workmanship rather than 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.

When it isn’t the sealant
We seal joints; we don’t mend everything behind them. On its own, sealant can’t deal with:
- Damp caused by condensation inside the building
- Providing access systems for the work
- Cracked or spalling substrates that need repair before sealing
If in doubt, speak to us on 01277 525 020 or email drawings and photos and we will say what we think before you book.
What we seal
- Cladding panel joints
- Perimeter joints where frames meet the structure
- Coping and flashing joints
- Shopfront frames
- Window and door perimeters
- Stone and brick facade joints
Cost factors for facade joints
We price every job individually. The main factors are:
- Access and working height
- Travel to remote or island sites
- How much existing material needs removing
- Joint width, depth and condition
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.
Details that help us quote
Diagnosis starts before we arrive. Let us know:
- The site address and postcode
- What the building is and how it’s used
- Anything awkward about access or site hours
- Drawings or a marked-up plan, if available
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 use the quote form.
Doing it in-house
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.
Putting right a botched joint often costs more than sealing it well at the start, since all of it has to come out and the faces be cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
Surface by surface
Render and coated surfaces
Rendered and painted facades need a sound edge for the sealant to bond to. We remove flaking material so the bead bonds to a firm surface, and we’ll mention any edges that need repair.
Cladding panel joints
Where panels are sealed rather than open-jointed, the bead is part of the weather line. Failed runs are cut out and rebuilt end to end to the correct depth.

How a job runs
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed, then reopened once the sealant allows before the next one starts. What matters most for a job in Redbourn is a clear list of what needs doing. A fixed quote follows.
- We look at the joints, the drawings and the access before pricing.
- The old bead is cut away completely, not overlaid.
- Joint faces are cleaned to firm, sound material, with primer where the sealant maker specifies it.
- 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.
