Common questions from Tyttenhanger clients
Is a smaller place like Tyttenhanger outside your area?
No. Places such as Tyttenhanger are covered as much as the big towns. London and every South East county are within our area. Good photos up front let us bring everything on the first visit.
Will you take on work at estates like The Albert Bygrave Retail Park, close to Tyttenhanger?
Yes. Our area takes in Tyttenhanger and its surroundings, with estates and business parks such as The Albert Bygrave Retail Park included. Send details of the unit and the work through our quote form for a quick quote.
Will rain stop the work?
We can work through the year, but sealant needs a dry joint and temperatures within the product’s range. Frost and condensation on glass and steel are common on winter mornings, so we plan around the forecast.
Is any job too small?
We quote for single jobs as well as large packages and programmes. Photos and a description are enough to start.
Can you work to our specification?
Yes. Send it with your enquiry, and the quote will be based on it.
Is your workmanship covered by a guarantee?
Yes. Workmanship is guaranteed for 12 months on every job.
Can staff carry on working while you’re here?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.

When to call us in Tyttenhanger
Not every failure is in the sealant: if the edge of the render, concrete or coating breaks away, the bead goes with it. We tell you when the edges need repairing before resealing.
Site and facilities staff are often the first to spot these:
- Draughts around frames and panels
- Water coming in around window frames
- Discoloured or dirty facade joints
- Hard, chalky sealant that no longer flexes
School extensions, at buildings such as Nicholas Breakspear School, normally run to the summer holidays, mastic included.

Keeping the joints sound
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. Our advice:
- Brief window cleaners about newly sealed joints
- Inspect facade joints on a regular cycle
- Clear debris that holds water against joints
- Combine resealing with other works that need access
Look at perimeter and panel joints as part of routine building checks. Watch for splits, gaps at the edges, hardening and discolouration; note where they appear.
In pre-2000 buildings, check the asbestos register before old sealant is cut out. Some older mastics contain it.

What else we do in Tyttenhanger
Our process
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. On site, the work usually takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather, and our waste is bagged and taken away as we go. Rural sites near Tyttenhanger may need directions, gate codes or a contact on site. Send that with the details and we’ll confirm the plan with the quote.
- Access, site rules and timing are settled with the client up front.
- Weather and temperature are checked against the product’s limits.
- Each joint is cut out and the edges inspected.
- Joints are cleaned, primed if required and fitted with backing rod.
- Sealant is gunned in and tooled hard onto both faces.
- Once signed off, the work carries our 12-month guarantee.
Getting the site ready
- Warn occupants and staff about the work
- Confirm the product named in the specification
- For older buildings, check the asbestos register before work

Site staff or a sealant specialist?
Paperwork matters too. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
For most general trades, sealant is a sideline. A specialist prepares properly, controls joint depth and picks a product with the right movement class.
Building and refurbishing in Tyttenhanger
A number of hotels sit less than 2 miles from Tyttenhanger. When hotels extend or refit, the work is typically squeezed between peak periods, mastic included. Tyttenhanger is in the South East, one of the UK’s drier regions. Winter mornings still bring frost and condensation on frames and panels, so the external programme keeps a little slack.
Projects at colleges like Oaklands College (to the north of Tyttenhanger) tend to run to term dates, so the mastic is planned tightly. For a contractor working at a hospital such as Kingsley Green Hospital, which lies south of Tyttenhanger, perimeter and facade sealing is planned around patients and deliveries.

Different surfaces, different methods
Coping and flashing joints
Coping and flashing joints are included where sealant is the specified fix. These joints take full exposure to weather, so preparation and product choice matter.
Cladding panel joints
Joints between cladding panels open and close with temperature. The sealant has to match the movement and the panel finish, often a low-modulus silicone or hybrid.
Leave it or put it right?
Leaving failed perimeter sealant also makes the eventual job bigger: wet edges break down, so repairs may be needed before resealing. Early action keeps it simple. Converted and older buildings near places like Tyttenhanger tend to move, and aged sealant cracks. A sealant with the right movement capability, correctly sized, lasts far better.
There’s no price list, since every building and every scope is different. For a fixed figure, call for a quote and we’ll price your job on its own details.
