General trades versus a specialist
General builders and handymen seal joints, but it isn’t their main trade. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Site maintenance staff can often handle a short internal joint. The usual problems come from preparation: new sealant over old, damp or dusty faces, or the wrong product for the movement.
How we handle facade sealing in Galleywood
External joints face UV, rain, temperature swings and building movement all year. Life depends on movement, weathering, product choice and the quality of the original work. When it fails, the whole bead is cut away and the joint rebuilt. If you’re dealing with perimeter joints where frames meet the structure and failed sealant on precast panel joints, we can help. Looking for mastic applicators who cover Galleywood? Mastic Doctor has worked for contractors, FMs and building owners since 2005, with CSCS-carded applicators.
Building work in places the size of Galleywood is usually small-scale: a handful of new houses, barn conversions, a school or hall extension. Small schemes still need window perimeters, facade joints and internal sealant done to the specification.
We stand by our work: 12 months, guaranteed. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

Diagnose, treat, sign off
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself normally 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. Work in places the size of Galleywood is planned as a single visit where we can. Photos with rough sizes let us arrive with everything needed.
- Access, site rules and timing are settled with the client up front.
- We only seal when joints are dry and within the product’s temperature range.
- Each joint is cut out and the edges inspected.
- Faces are cleaned, primed where needed and backed.
- Sealant is gunned in and tooled hard onto both faces.
- Once signed off, the work carries our 12-month guarantee.
What we need from you
- Warn occupants and staff about the work
- Send asbestos survey details if the building is pre-2000
- Explain the parking and delivery arrangements

Galleywood: questions and answers
Can work at a site such as Anglia Ruskin University fit around teaching?
Yes, holiday working periods are the norm on campus jobs. We’re CHAS accredited and a Constructionline member, and paperwork such as RAMS is confirmed with the quote.
Can you take on a job at a hospital such as Phoenix Hospital?
Yes, healthcare and care buildings are part of our work. Each area is agreed with the ward or department and the estates team in advance.
Is it fine to apply new sealant on top of old?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
Do we need an asbestos check before resealing?
In older non-domestic buildings, old sealant can contain asbestos. The dutyholder’s asbestos register should be checked first, and if anything is suspected, we stop until it’s tested. Removal of asbestos isn’t something we do.
What about RAMS and site documents?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we will confirm with the quote.
How is access to upper-level joints handled?
We agree access with the client at the start. Let us know what access is in place or planned, and the quote will reflect it.
How long will the new sealant last?
There’s no fixed lifespan: movement, exposure, cleaning, traffic and the product all play a part. Treat them as maintenance items and inspect them regularly.
Building and refurbishing in Galleywood
The South East is one of the drier parts of the UK. Winter mornings still bring frost and condensation on frames and panels, so we time external mastic for dry faces and agree it with the site team. Galleywood lies roughly 28 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.
School extensions, at buildings such as St Michael's Church of England Voluntary Aided Junior School, typically run to the summer holidays, mastic included. For contractors on a campus like Anglia Ruskin University (2.9 miles north of Galleywood), facade and perimeter sealing has to fit around students and term dates. New units and refits on sites such as Beehive Business Centre, 1.5 miles north of Galleywood, need their panel and perimeter joints sealed to the specification.

Maintenance after handover
After handover, these steps help:
- Never let anyone seal over old sealant
- Check that rainwater leaves the facade the way it was designed to
- Plan facade sealing alongside redecoration
- Investigate damp beside windows promptly
Keep gutters, sills and drainage paths clear. Sealant copes better when water runs off the facade as designed rather than sitting against the joints.
Deal with sections that fail early as soon as they show. A few metres resealed promptly can stop water damage spreading behind the facade.
Different surfaces, different methods
Cladding panel joints
Where panels are sealed rather than open-jointed, the bead is part of the weather line. Failed runs are cut out and rebuilt end to end to the correct depth.
Coping and flashing joints
Coping and flashing joints are included where sealant is the specified fix. These joints take full exposure to weather and need a durable external sealant.
