Granborough: questions and answers
Is Granborough off your patch?
No. Small places get the same service as large ones. Our area covers London and the South East counties. Good photos up front let us bring everything on the first visit.
Can the mastic package for our job in Granborough follow the site programme?
Yes. The mastic is planned around your key stages. Any paperwork you need, from RAMS to our insurance certificate and CSCS details, is confirmed with the quote.
How long will the new sealant last?
It depends on movement, UV and weather, cleaning, traffic and the product. Sealant joints are maintenance items, so inspect them regularly.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
Can one quote cover more than one building?
Yes. Multi-site work and planned programmes are a core part of the service, planned site by site to suit how each building is used.
Do you need to see the site first?
It depends on the job. Straightforward work can often be priced from photos and measurements, while larger or less clear jobs get a site visit first.
Is old mastic on our building likely to contain asbestos?
It’s worth checking in any building from before 2000. The duty to manage asbestos sits with the dutyholder. Suspect material is left alone until it has been tested.
Facade sealing in Granborough, done properly
Weather decides a lot in facade sealing. The sealant needs a dry joint and temperatures inside the maker’s limits. We build that into the programme and tell you if the forecast changes the plan. If you’re dealing with water coming in around window frames and gaps between rainscreen or cladding panels, we can put it right, whatever the surface. Most enquiries from Granborough start with one failed joint and grow into a wider look at the building: we look at the rest while we’re there and tell you what we find.
Conversions of older rural buildings near smaller places such as Granborough bring stone, flint, brick and timber up against new glazing. A product that grips an irregular face, with a colour that suits the building’s character, is usually what’s needed.
Our workmanship is guaranteed for 12 months. If a joint we sealed fails because of how it was installed, we come back and put it right.

Keeping the joints sound
Once the work is signed off, these steps help:
- Avoid harsh cleaners on facade sealant
- Clear debris that holds water against joints
- Ask about asbestos in pre-2000 mastic
- Don’t wait for a second leak before calling
Anything drilled through a facade joint breaks the seal. Make sure the joint is resealed afterwards with a compatible product.
Planned resealing is cheaper than reacting to leaks. Regular checks let you renew joints before water gets in, rather than waiting for a ceiling stain.

What happens if it’s left?
Failed joints let in more than water: draughts around frames add to heating costs and complaints. Resealing deals with the draught as well as the leak. One visit to deal with every failing joint makes more sense than several trips to a place like Granborough, rather than one at a time. Send photographs of each area and we’ll quote for the lot.
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.

Mastic packages on Granborough sites
Granborough sits in one of the drier corners of the country, the South East. Winter mornings still bring frost and condensation on frames and panels, so external mastic is timed for workable conditions and agreed with the site manager. Granborough lies roughly 45 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.
For contractors refurbishing units at places like Station Road Industrial Estate, 2 miles north of Granborough, the mastic covers cladding panels, roller-door and window perimeters. Work at a hotel such as The Bell Hotel, 1.5 miles north of Granborough, tends to be programmed around bookings, mastic included. When a school such as Sir Thomas Fremantle School is extended or refurbished, the mastic package is often squeezed into the holidays.
Granborough is about 7 miles south-east of Buckingham, in Buckinghamshire. Businesses, contractors and managing agents in Granborough use us for work on facade joints, as part of our coverage of Buckinghamshire.

Diagnose, treat, sign off
Site rules come first: sign-in, induction and whatever permit system the building uses. Once we’re cleared to begin, we take the joints in the sequence agreed with you, and each area is checked before we leave it. Rural sites near Granborough may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.
- First we review photos, 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.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.
- 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.
Getting the site ready
- Tell staff and tenants when we will be in
- Have the specification and drawings to hand
- Share your working hours and any access restrictions

Owners, agents and contractors
When you manage a building on behalf of an owner, you need clear quotes and clear reporting. We quote a fixed sum, confirm the scope and walk the finished work with you or your representative, plus a 12-month guarantee.
Planned maintenance programmes are welcome: working through a building or an estate in stages that fit your budget. Sites in Granborough can sit alongside others in a wider programme across Buckinghamshire.
What the job involves on each surface
Window and door perimeters
Aluminium, PVC-U and timber frames each have their own preparation needs. We clean and prime to the sealant maker’s guidance for each 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 areas needing repair are flagged.
How the quote is worked out
Your fixed quote is built from the real scope. It takes account of:
- Working within restricted access windows
- Which sealant the job calls for
- Any access equipment needed
- Distance, for remote addresses
The price depends on the quantity of joints, what has to come out first and the access. Call for a fixed quote once you have the details.
What to include in your enquiry
Good information means a firmer quote. When you get in touch, include:
- Where the site is, with the postcode
- How the joints are reached, and at what height
- Any specification or named product
- Drawings or a marked-up plan, if available
Let us know the site, the scope and your timescale, and we will put a fixed quote together. To get it moving, speak to us on 01277 525 020 or email drawings and photos.
