Lye Green: questions and answers
Can you take on a job at a hospital such as Amersham Hospital?
Yes, healthcare and care buildings are part of our work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Could you schedule work at a campus like Buckinghamshire New University for the vacation?
Yes. We plan campus work around teaching, exams and residence turnarounds. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
How long does a job like this take?
It depends on the scope, but the work typically takes a day or two for a few elevations, and longer where access has to be moved around the building. Larger or phased jobs take longer, and we will give you a timescale with the quote.
Can you work to our specification?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it.
Do you install glazing systems?
No. A glazing contractor handles that. What we seal are the joints around frames and panels on commercial buildings.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.

Facade sealing for commercial buildings in Lye Green
Weather decides a lot in facade sealing. Joints have to be dry and the air and surface temperature within the product’s range, and cold, damp starts can delay work. We build that into the programme and tell you if the forecast changes the plan. If you have weathered joints at frame-to-structure perimeters and cladding panel joints that have opened up, we can put it right, on cladding panel joints, coping and flashing joints and window and door perimeters alike. Sealant contractors, mastic applicators, sealant specialists: whatever the job title on the order, the work in Lye Green is the same: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Construction in and around smaller places such as Lye Green is often barn conversions, small groups of houses or extensions to halls and schools. Perimeters, facade joints and internal sealant all need doing properly, however small the scheme.
Guaranteed is the last step of every job. Our workmanship is backed for 12 months, and we explain exactly what that covers when we quote.

On site: what to expect
Working in a building that stays open takes some planning. We sign and contain the area we’re in, with routes through the building left open and work section by section so the rest of the building stays in use. Smaller jobs around Lye Green can be grouped with others nearby, which keeps travel down. A fixed quote is given before anything starts.
- 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.
What we need from you
- Tell us what induction or permit system the site runs
- Confirm the product named in the specification
- Point out any areas we must not close

What sets the cost
There’s no standard rate for sealant work, since sites vary so much. What we take into account:
- Travel to remote or island sites
- Access and working height
- Whether the work must be split into stages
- Joint width, depth and condition
Small jobs and large programmes are priced from the same things: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.
Sending details for a quote
There’s no need for a formal survey. A few details are enough to get going:
- The asbestos register, for older buildings
- Your programme or deadline
- Specification clauses that apply
- The postcode of the building
For a fixed quote, call the office on 01277 525 020 or email drawings and photos. Our quote form is another easy route.
What the job involves on each surface
Brick and stone facades
Joints in natural stone need care to avoid staining. The specified stone-compatible sealant is what we use.
Coping and flashing joints
Where the specification calls for sealant at copings or flashings, we can seal them. They sit in the most exposed positions on the building and need a durable external sealant.
Looking after the joints
Problems stay small when the joints are checked regularly. Specifically:
- Record the product and colour used on each elevation
- Clear debris that holds water against joints
- Never let anyone seal over old sealant
- Check the asbestos register before old mastic is disturbed
Keep a note of which product went in and when. Future work can then match the product and colour.
Planned resealing is cheaper than reacting to leaks. Regular checks let you renew joints before water gets in instead of after the damage.

Owners, agents and contractors
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 will confirm with the quote.
Hospitality, education, healthcare, office and retail clients come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.
What we are called out for in Lye Green
Not every failure is in the sealant: crumbling render, spalling concrete or flaking paint take the sealant with them. We tell you when the edges need repairing before resealing.
Clients usually get in touch after noticing something like this:
- Damp patches beside frames after rain
- Weathered joints at frame-to-structure perimeters
- Sealant pulling away from frames or panels
- Weathered facade joints that have lost their grip
Historic houses such as Chenies Manor House, 3.8 miles south-east of Lye Green, are a reminder of the older buildings in the wider area, where sealing against old stone, brick or timber needs compatible products.

Facade sealing around Lye Green: what changes locally
Lye Green is in the South East, one of the UK’s drier regions. Winter mornings still bring frost and condensation on frames and panels, so we time external mastic for dry faces and agree it with the site team. Central London is about 26 miles from Lye Green. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, which keeps mastic packages in demand.
For contractors on a campus like Buckinghamshire New University, which lies south-west of Lye Green, facade and perimeter sealing has to fit around students and term dates. When units on a site such as Waterside Business Park, 1.8 miles south-west of Lye Green, are refurbished or reclad, the panel joints and window perimeters are part of the mastic package.
