Common questions from Havering-atte-Bower clients
Is hospital work, at somewhere like Victoria Hospital, something you do?
Yes. We work in healthcare settings as well as offices and schools. We follow the site’s permits, sign-in and infection-control procedures in every area.
Can you work in a London building with booked loading and goods-lift slots?
Yes. Inductions, permits and timed loading are routine for us in London. The building manager’s rules go straight into our method.
How much does the work cost?
We don’t publish prices, as every site differs. With photographs or drawings, we can give you a fixed quote.
Are you CHAS accredited?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
Who decides which product is used?
Where there’s a specification, we use the product it names. Otherwise, we recommend a product to suit the joint’s movement, the substrate and the conditions, following the manufacturer’s guidance.
Are you insured?
Yes. We’re fully insured, including public liability cover.
When can the area be used after sealing?
We will confirm how long the chosen product needs to cure.
Facade sealing for commercial buildings in Havering-atte-Bower
Every facade quote starts with how the joints will be reached. Let us know what access exists or is planned, and any site rules we need to work around, so the price covers the real job. If you have leaks at window and door perimeters and perimeter joints where frames meet the structure, we can put it right, on cladding panel joints, perimeter joints where frames meet the structure and stone and brick facade joints alike. A specialist sealant contractor works differently from a general builder: on jobs in Havering-atte-Bower, preparation and product choice get the time they need.
Every London site, Havering-atte-Bower included, is inside the ULEZ, which applies to deliveries and contractors’ vans alike. Alongside that, sites normally need booked deliveries and a plan for where materials go.
We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant.

Different surfaces, different methods
Coping and flashing joints
Sometimes the coping or flashing itself has failed. We tell you if the fix is a roofing or metalwork job rather than a reseal.
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 to the correct depth.
Signs you need facade sealing in Havering-atte-Bower
Not every failure is in the sealant: if the edge of the render, concrete or coating breaks away, the bead goes with it. When the joint edges need repair first, we say so.
Things that typically lead to an enquiry:
- Failed sealant on precast panel joints
- Facade joints cracked through the middle
- Unsightly perimeter sealant on a visible elevation
- Failed seals around shopfront and entrance frames
Extensions at sites like Victoria Hospital, 2.5 miles to the south of Havering-atte-Bower, typically sit beside working departments, and the mastic follows strict access rules.

How a job runs
Before any cutting starts, the area is protected: tape along each joint edge and covers over finishes, stock and equipment close by. On site, the work typically takes a day or two for a few elevations, and longer where access has to be moved around the building, and we clear our waste as we work. Most London premises stay occupied while we are on site, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- We plan access and the order of elevations with the client.
- Weather and temperature are checked against the product’s limits.
- Each joint is cut out and the edges inspected.
- Joints are cleaned, primed if required and fitted with backing rod.
- Sealant is gunned in and tooled hard onto both faces.
- We hand over with our 12-month workmanship guarantee.
Getting the site ready

Maintenance after handover
To get the most from the new sealant:
- Record the product and colour used on each elevation
- Keep sills, gutters and drainage paths clear
- Check the asbestos register before old mastic is disturbed
- Avoid harsh cleaners on facade sealant
Hold back any cleaning crew until the joints have had their stated cure time. 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, and work stops until it’s tested if it’s suspected.
Why deal with it now?
Every shower drives water through a split perimeter bead. The damage builds out of sight: wet linings, rusting fixings, staining and spoiled finishes. Resealing now costs less than repairing interiors later. Access in London is hard enough to arrange once, so while access is arranged it pays to renew all failing joints, not just the worst.
The work involved drives the cost: stripping out, preparation, sealing, access and phasing. Call for a quote.

Building and refurbishing in Havering-atte-Bower

Access in Havering-atte-Bower needs thought: the ULEZ covers all of Greater London, and loading and parking are rarely simple. When a college such as Havering Technical College (to the east of Havering-atte-Bower) builds or refurbishes, the mastic package typically has to fit around students and staff.
