Mastic packages on Burnham Green sites
Burnham Green lies roughly 23 miles out from central London. Commuter-belt towns tend to see a steady flow of new flats, offices and commercial schemes, and each scheme needs its mastic sealed to programme. The South East is one of the drier parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so the external programme keeps a little slack.
For contractors refurbishing units at places like Little Ridge Industrial Estate, which lies south of Burnham Green, the mastic covers cladding panels, roller-door and window perimeters. For contractors at a school such as Monk's Walk School, sealing has to be finished before term starts. For a contractor working at a hospital such as Queen Elizabeth II Hospital (3.6 miles south of Burnham Green), perimeter and facade sealing is planned around patients and deliveries.
Burnham Green is about 3 miles north-east of Welwyn Garden City, in Hertfordshire. We send applicators to Burnham Green for facade joints, handled exactly as we handle every other area.

About our facade sealing in Burnham Green
Access is part of every facade job, and we plan it with you before quoting. Tell us about access: whether scaffold is already up, what the client is arranging, and any restrictions on the site. If you’re dealing with new sealant peeling off old mastic and weathered facade joints that have lost their grip, we can help, whatever the surface. A single leaking joint is often how a building in Burnham Green first comes to us: we check the joints around it and give you an honest view of what needs doing now and what can wait.
For a site near Burnham Green, the mastic visit is planned so the right sealants, primers and backing rod are on hand. Drawings, photos and the programme let us give a fixed quote.
We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant.

Keeping the joints sound
Every sealant joint needs some looking after, and how long they last depends on how they’re treated. We suggest:
- Walk the elevations once or twice a year
- Insist on a full cut-out when joints are renewed
- Don’t wait for a second leak before calling
- Combine resealing with other works that need access
Let the new sealant cure before washing the facade or windows near it. Keep high-pressure jets and strong chemicals away from new sealant.
Don’t wait for a full elevation to fail. A few metres resealed promptly can stop water damage spreading behind the facade.
Commercial clients in Burnham Green
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’ll confirm with the quote.
Housing associations and managing agents often need work done across blocks and communal areas. Work can be phased so residents and staff keep access throughout, and each stage is agreed with your contact.
Should maintenance staff do it?
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. A poor seal in places like these tends to cost more to put right later.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and we will confirm the paperwork you need with the quote.
What happens if it’s left?
Each spell of rain drives water past a failed facade joint. The damage builds out of sight: wet linings, rusting fixings, staining and spoiled finishes. Resealing now costs less than repairing interiors later. One visit to deal with every failing joint makes more sense than several trips to a place like Burnham Green. Send photographs of each area and we will quote for the lot.
We don’t publish prices, since every building and every scope is different. For a fixed figure, call for a quote and we will price your job on its own details.

How the quote is worked out
There’s no standard rate for sealant work, because every site is different. What we look at:
- Whether the work must be split into stages
- Location, for remote and island sites
- Joint width, depth and condition
- Any access equipment needed
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 we will put a fixed figure on it.
What we need to price the job
We can often quote from photos and a few details. It helps to include:
- Access details, including height
- Approximate linear metres or a joint schedule
- The postcode of the building
- Your programme or deadline
Let us know the site, the scope and your timescale, and we’ll put a fixed quote together. To get it moving, phone 01277 525 020 or send photos by email.
Burnham Green: questions and answers
Is Burnham Green off your patch?
Not at all. Burnham Green is within our area. Our area covers London and the South East counties. We plan jobs in smaller places so return trips are kept to a minimum.
Would you work within a site like Queen Elizabeth II Hospital?
Yes. Healthcare sites are among the places we work. Before anything starts, the estates team agrees permits, inductions and infection-control measures with us.
Are your applicators CSCS-carded?
Yes. We use CSCS-carded applicators, as many construction sites ask for.
How long before the joints can be used?
That comes down to the sealant and the temperature. Some products skin over quickly but need longer to cure fully, so we’ll confirm the curing time on the day.
Do you seal on top of existing sealant?
No. Failed sealant is removed and the faces cleaned back to sound, dry material first, because fresh silicone will not bond with aged silicone.
What do you charge?
That depends on the job: quantities, access, the product and any phasing. Call for a fixed quote and we will price it properly.
Can you work while the building is occupied?
In the majority of cases, yes. We phase the work so most of the building stays in use.
From enquiry to sign-off
We begin with a short walk round with whoever looks after the building, to confirm the scope, the order of work and any areas we must keep clear. Then we strip out anything that has failed, prepare every joint and seal it. Smaller jobs around Burnham Green can be grouped with others nearby, which keeps travel down. You will have a fixed quote before work starts.
- We look at the joints, the drawings and the access before pricing.
- Failed sealant is cut out along its full length.
- Both faces are cleaned and, where the product needs it, primed.
- Backing rod, or bond-breaker tape in shallow joints, limits the depth.
- A facade-grade sealant rated for the movement goes in, tooled to a concave profile.
- We walk the finished joints with you before handing over.
Preparing the site
- Confirm the product named in the specification
- Share your working hours and any access restrictions
- Flag any permit to work we will need
