Common problems we fix in Pegsdon
Most facade joints fail through age and weathering. The bead hardens, chalks on the surface and loses the flexibility to follow the joint.
Any of the following is a good reason to get the joints checked over:
- Hard, chalky sealant that no longer flexes
- Perimeter joints where frames meet the structure
- Water coming in around window frames
- New sealant peeling off old mastic
On a healthcare site such as Keech Hospice Care (3.6 miles south-west of Pegsdon), new blocks and refurbishments go on while the hospital keeps running, so mastic work is sequenced carefully.
What to look for in a quote
- Whether old or failed sealant will be cut out, not overlaid
- Health and safety accreditation such as CHAS
- Their approach to joint depth and backing
- Whether their applicators hold CSCS cards
Facade sealing in Pegsdon, done properly
Facade sealants sit in the sun, rain and frost every day. How long a joint lasts depends on the movement it takes, its exposure, the product and how well it was installed. When the time comes, we cut the old sealant out completely and start again. Most enquiries involve facade joints cracked through the middle and staining on stone next to old sealant, across stone and brick facade joints, cladding panel joints and window and door perimeters. A specialist sealant contractor works differently from a general builder: on jobs in Pegsdon, preparation and product choice get the time they need.
Sites around smaller places like Pegsdon can be a fair drive from suppliers, so we come with everything the package needs. Send drawings or photographs and the programme and we will quote to suit.
We stand behind the joints we seal: 12 months, guaranteed. That covers our preparation and application.

Contractors’ notes for Pegsdon
Pegsdon lies roughly 34 miles out from central London. Towns within reach of London tend to keep building, from flats to offices and schools, so mastic packages have to keep pace with busy programmes. The South East is one of the drier parts of the UK. Even so, frost and condensation on steel and glass are common on winter mornings, so the external programme keeps a little slack.
New units and refits on sites such as Manor Farm Business Park (to the north-west of Pegsdon) need their panel and perimeter joints sealed to the specification. When a school such as Hexton Junior Mixed and Infant School is extended or refurbished, the mastic package is often squeezed into the holidays.
Pegsdon is about 4 miles west of Hitchin, in Hertfordshire. Across the SG5 postcode area, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed.

From enquiry to sign-off
Tell us your site hours and access windows and we will plan around them. On the day, the work area is kept contained and tidy, and your contact hears from us before we move to the next area. For work around Pegsdon, we aim to finish in one visit, so we ask for photographs and rough sizes first. That way the right products come on the day.
- First we review photographs, 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.
- 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.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- The completed runs are checked with you, then the 12-month guarantee applies.

How the job changes by surface
Render and coated surfaces
Paintable sealants exist for joints that will be coated. We confirm the product with you before starting.
Window and door perimeters
Frame-to-wall joints at windows and doors are the facade joints we reseal most. A low-modulus neutral-cure product, chosen for the frame and wall, goes in finished to throw water off the joint.
Pegsdon: questions and answers
Could you schedule work at a campus like University of Bedfordshire for the vacation?
Yes, holiday working periods are the norm on campus jobs. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
Do you take on work at healthcare sites like Keech Hospice Care?
Yes, healthcare and care buildings are part of our work. Work is phased so departments keep running, under the site’s own rules.
Are you fully insured?
Yes. We’re fully insured, including public liability cover.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Treat them as maintenance items and inspect them regularly.
Do you provide access for facade work?
That varies with the building and the access on offer. Share what access exists or is planned when you send details, and we’ll plan the work with you.
Is it okay to overlay old mastic?
No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely. That is what makes the new joint last.
What type of sealant goes on window perimeters?
Most facade and window perimeter joints take a low-modulus neutral-cure silicone. Some joints call for hybrid, PU or polysulphide instead.
For managing agents and facilities managers
Housing associations and managing agents often need work done across blocks and communal areas. We phase the work so people keep access, and each stage is agreed with your contact.
Facilities managers want contractors who arrive with the paperwork sorted. Tell us what site paperwork you need, such as RAMS, an insurance certificate or CSCS details, and we’ll confirm with the quote.
