Facade sealing in Letchworth Garden City
Facade sealants sit in the sun, rain and frost every day, and they wear out over time. How long a joint lasts depends on the movement it takes, its exposure, the product and how well it was installed. When it fails, the whole bead is cut away and the joint rebuilt. If you’re dealing with new sealant peeling off old mastic and damp patches beside frames after rain, we can help, on shopfront frames, window and door perimeters and coping and flashing joints alike. A specialist sealant contractor works differently from a general builder: in Letchworth Garden City, that means joint design, primers and backing rod as standard.
Older town-centre buildings in places like Letchworth Garden City are often converted to new uses or extended, which puts new frames and panels against old brick, stone or render. Getting the product and primer right for both faces is what keeps those joints sound.
A 12-month guarantee applies to all our work. If an installation problem shows up, give us a call on 01277 525 020 or email a schedule or drawings and we’ll arrange a return visit.

Maintenance after handover
Problems stay small when the joints are checked regularly. Specifically:
- Keep pressure washers away from fresh sealant
- Ask about asbestos in pre-2000 mastic
- Record the product and colour used on each elevation
- Combine resealing with other works that need access
Include facade joints in your planned maintenance inspections. Watch for splits, gaps at the edges, hardening and discolouration; record the locations.
Check older buildings for asbestos before disturbing old mastic. Some older mastics contain it.
Building and refurbishing in Letchworth Garden City
Letchworth Garden City sits in one of the drier corners of the country, the South East. Still, external mastic needs dry faces within the maker’s temperature limits, which isn’t every day, so we time external mastic for dry faces and agree it with the site team. There are several hotels within about 2 miles of Letchworth Garden City. Hotel refurbishments often run to tight programmes between busy periods, and perimeter and sanitary sealant has to keep up.
Units on estates such as Letchworth Gateway Retail Park (to the east of Letchworth Garden City) tend to be reclad and refitted as tenants change, and each job leaves cladding and perimeter joints to seal. For a contractor working at a hospital such as Pinehill Hospital, which lies south-west of Letchworth Garden City, perimeter and facade sealing is planned around patients and deliveries. For contractors at a college like North Hertfordshire College - Hitchin Campus, which lies south-west of Letchworth Garden City, perimeters and internal sealant are timed for the holidays.

What sealant work can’t fix
Part of a good diagnosis is knowing where sealant stops. You will hear from us if the cause turns out to be one of these:
- Damp caused by condensation inside the building
- Work on the window or framing system itself
- Providing access systems for the work
If in doubt, give us a call on 01277 525 020 or send photos by email and we’ll say what we think before you book.
Joints and surfaces we work on

Doing it in-house
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
What you see is the finished bead, but most of the work is hidden. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Your questions answered
Is a hospital such as Pinehill Hospital somewhere you can work?
Yes, provided the work is planned with the site’s estates team. Work is phased so departments keep running, under the site’s own rules.
Could you schedule work at a campus like North Hertfordshire College - Hitchin Campus for the vacation?
Yes. We plan campus work around teaching, exams and residence turnarounds. Let us know which documents your site asks for, and we will confirm them alongside the quote.
Will rain stop the work?
Wet joints or temperatures outside the product’s range mean waiting. We plan for weather and keep you updated as the work goes on.
Can you send site paperwork?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote.
How do I request a quote?
You can use the quote form on this site; alternatively, phone 01277 525 020 or send details through our quote form. Photos, drawings or a joint schedule help us quote quickly.
Can one quote cover more than one building?
Yes. Several buildings can share a single quote, and you deal with one contact throughout across South East England, Greater London and Scotland.
Do you run new sealant over the existing bead?
No. A bead run over old sealant soon lifts. Our method is a full cut-out, cleaning, backing and a new bead.
