Facade sealing in Middlegreen
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. We work on coping and flashing joints, shopfront frames and window and door perimeters, and the failures we are asked to look at most are air leaks through failed facade joints and failed seals around shopfront and entrance frames. Looking for mastic applicators who cover Middlegreen? We’ve been sealing commercial buildings since 2005, with CSCS-carded applicators.
Sites around smaller places like Middlegreen can be a fair drive from suppliers, so we come with everything the package needs, timed to the stage the job has reached. Send drawings or photographs and the programme and we’ll quote to suit.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

Cost factors for facade joints
Quotes vary with the job. Expect it to depend on:
- How much existing material needs removing
- Distance, for remote addresses
- The product specified
- The site’s rules and procedures
Whether it’s a single area or a whole estate, the same things set the price: scope, access, product and programme. Call for a quote and we will put a fixed figure on it.
What to include in your enquiry
The more we know, the firmer the quote. Helpful details to send:
- Drawings or a marked-up plan, if available
- The site address and postcode
- Asbestos survey details if the building is older
- Any dates the work must fit around
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Send what you have, and we’ll arrange a site visit if anything is unclear.

What we are called out for in Middlegreen
Product choice matters: acetoxy-cure silicone may mark stone or corrode certain metals, and an interior product won’t last outdoors. Most external joints call for a neutral-cure, facade-grade sealant.
Most enquiries start with something like this:
- Air leaks through failed facade joints
- Discoloured or dirty facade joints
- Facade joints cracked through the middle
- Previous reseals run over old sealant
University estates such as Brunel University of London, 3.9 miles north-east of Middlegreen, tend to have a rolling programme of new buildings and refurbishments, each with window perimeters and facade joints to seal.
Questions to ask before you book
- Will RAMS and insurance details be available?
- How joint depth will be controlled
- Will CSCS-carded applicators be on site?

Questions we’re asked in Middlegreen
Is Middlegreen off your patch?
No. Places such as Middlegreen are covered as much as the big towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Does your area include sites such as Deseronto Trading Estate, near Middlegreen?
Yes. Our area takes in Middlegreen and its surroundings, with estates and business parks such as Deseronto Trading Estate included. To start, just ring 01277 525 020 or email a schedule or drawings with the unit, the joints involved and your access times.
Is it okay to overlay old mastic?
No. Fresh silicone won’t grip cured silicone, so the existing bead is removed entirely and the faces are cleaned before resealing. Nothing else gives a bond that lasts.
Can you send site paperwork?
Requirements differ from site to site, so list what you need, whether RAMS, insurance or CSCS details, and we’ll confirm with the quote.
Do you hold CHAS accreditation?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
What hours do you work?
We are in the office from 8am until 5pm, Monday to Friday. Tell us your site hours and access windows and the work will be fitted around them.
Do your applicators hold CSCS cards?
Yes. Should the site need card details in advance, let us know and we’ll send them with the quote.
Facade sealing around Middlegreen: points for this area

From enquiry to sign-off
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. The work itself normally 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. Smaller jobs around Middlegreen 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.
- 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.
- We walk the finished joints with you before handing over.
Preparing the site
- Clear stock, furniture or equipment away from the joints
- Agree which areas must stay open
- Point out parking and an unloading spot

Site staff or a sealant specialist?
Redoing a failed joint typically costs more than getting it right at the outset, because the whole bead must be removed and the faces cleaned back again. For that reason, many FMs and contractors use a sealant specialist from the outset.
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.
Looking after the joints
After handover, these steps help:
- Keep sills, gutters and drainage paths clear
- Note when each elevation was last resealed
- Walk the elevations once or twice a year
- Insist on a full cut-out when joints are renewed
Let the new sealant cure before washing the facade or windows near it. Pressure washers and harsh cleaners can damage a fresh bead and tell your cleaning contractor.
Check older buildings for asbestos before disturbing old mastic. Some older mastics contain it.
