Sending details for a quote
It doesn’t need to be a full survey. These details are enough to start:
- Asbestos survey details if the building is older
- Clear photographs of the problem areas
- How the joints are reached, and at what height
- The postcode of the building
Every job follows the same four steps: send details, get a quote, we seal, guaranteed. The first step is to ring 01277 525 020 or email a schedule or drawings with what you know.
How we handle facade sealing in Downley
We are often asked to look at water coming in around frames. Failed perimeter sealant is a frequent cause, though that isn’t the only cause. If the evidence points away from the sealant, we say so before quoting. Site teams most often ask us about facade joints cracked through the middle and unsightly perimeter sealant on a visible elevation, on perimeter joints where frames meet the structure, coping and flashing joints and window and door perimeters. For commercial sealant work in Downley, you deal with one contact from quote to sign-off, whether it’s one building or several.
For a site near Downley, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Send drawings or photographs and the programme and we will quote to suit.
Whoever the client is, the cover is the same: twelve months on the work we carried out. Faults in the structure, damage and other trades’ work fall outside it, and we say so plainly.

Building and refurbishing in Downley
Rainfall across the South East, Downley included, is lower than in many parts of the UK. 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. Downley is about 31 miles from central London. Building activity in the commuter belt runs from new flats near stations to business park refurbishments, so mastic packages have to keep pace with busy programmes.
School extensions, at buildings such as The Downley School, typically run to the summer holidays, mastic included. For contractors on a campus like Buckinghamshire New University (Wycombe Campus) (1.6 miles south-east of Downley), facade and perimeter sealing has to fit around students and term dates. For a contractor working at a hospital such as Wycombe General Hospital, 1.7 miles to the south-east of Downley, perimeter and facade sealing is planned around patients and deliveries.
Downley is about 2 miles north-west of High Wycombe, in Buckinghamshire. Anywhere in HP13, it works the same way: send details, get a fixed quote, we seal, and the work is guaranteed.

How the job changes by surface
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, so preparation and product choice matter.
Cladding panel joints
Where panels are sealed rather than open-jointed, the bead is part of the weather line. We cut out failed joints along their full length and rebuild them.
Keeping the joints sound
Problems stay small when the joints are checked regularly. In particular:
- Check the asbestos register before old mastic is disturbed
- Inspect facade joints on a regular cycle
- Note when each elevation was last resealed
- Avoid harsh cleaners on facade sealant
Record the sealant type and date on the building file. It helps when matching repairs or planning the next reseal.
Planned resealing is cheaper than reacting to leaks. Regular checks let you renew joints before water gets in.
Questions we are asked in Downley
Is a hospital such as Wycombe General Hospital somewhere you can work?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Is Downley too small for you to travel to?
Not at all: smaller places are covered as well as towns. London and every South East county are within our area. Where we can, we group nearby jobs to make the most of each trip.
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, as the specification or substrate requires.
How do we ask for a quote?
You can use the quote form on this site; alternatively, speak to us on 01277 525 020 or use the quote form. Include photos or drawings if you have them.
Does weather matter for sealant work?
It can, for external work. Wet joints and cold, damp or frosty conditions stop the sealant bonding properly, so we watch the forecast and rearrange outside work if we have to. Internal work is far less affected.
How is access to upper-level joints handled?
That varies with the building and the access on offer. Share what access exists or is planned when you send details.
How long does a typical visit take?
It depends on the scope, though a typical visit typically takes longer on a full elevation than on a handful of window perimeters, and it always depends on dry weather. For bigger or phased jobs, we will set out a timescale with the quote.
Why deal with it now?
Resealing a few window perimeters is a small job; repairing water-damaged interiors and fixings is not. Water through a failed joint rarely stays where it starts, often turning up far from the joint. Halls, stores and units around places like Downley may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
Pricing facade joints depends on how many there are, their condition and the access, and any specification that applies. Ask us for a fixed quote.

When to bring in a specialist
The visible bead is only part of the job. Backing rod, primer where specified and a joint designed to move with the building are where general trades tend to cut corners.
Using site staff can make sense for a small touch-up, but anything bigger is another matter: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
