Mastic sealing for commercial buildings in Sudbury
We work for building owners, landlords with commercial or block portfolios, managing agents and housing associations. Many prefer a planned programme to one-off visits and we quote and schedule each building in turn. Most enquiries involve open joints in brickwork or panels and no planned programme for sealant, across shopfronts below residential blocks, window and door perimeters on blocks and communal entrances and stairwells. Whether you call it commercial sealant work, mastic application or joint sealing, in Sudbury it comes down to the same thing: the right product in a properly prepared joint.
Planning mastic work on a London block means notices to residents, access to flats and agreed working areas. We work to the agent’s notice and access plan, so residents know what’s happening.
We stand by our work with a 12-month guarantee. It covers how we prepared and applied the sealant, and if something we did falls short, we return to it.

On site: what to expect
Before any cutting starts, the area is protected: masking tape along the joint edges and sheeting over anything nearby. The work itself typically takes anything from a day to a few weeks, depending on the number of buildings and joints, 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. Areas are handed back as each section is finished.
- We check the asbestos register for older buildings and look at the joints.
- The products and programme are set out in a fixed quote.
- Failed mastic is removed completely.
- Joint faces are cleaned, backed and resealed.
- Buildings are completed in turn.

Quoting for work in Sudbury
Quotes vary with the job. Expect it to depend on:
- How accessible the joints are
- Location, for remote and island sites
- The site’s rules and procedures
- How much there is to seal
What a job costs comes down to how many linear metres there are, what has to come out first and the access. Call for a fixed quote once you have the details.
What to include in your enquiry
A good diagnosis starts with the right details. Tell us:
- A wide shot and a close-up of the area
- The site address and postcode
- Any dates the work must fit around
- The product your specification calls for
A handful of photos and a postcode is the fastest way to a quote. Send them through the quote form, or call 01277 525 020 or send details through our quote form to discuss it first.
Should maintenance staff do it?
Putting right a botched joint often costs more than sealing it well at the start, 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.
A short, simple internal joint is often within reach of a maintenance team. Where it goes wrong is preparation: sealing over old material, sealing onto damp or dusty surfaces, or a product that can’t take the movement.
Aftercare for building managers
To get the most from the new sealant:
- Start inspections with the most exposed faces
- Check sealant joints during planned building inspections
- Plan resealing building by building rather than complaint by complaint
- Share your contractor requirements early
Include sealant in planned building inspections. Watch for splits, open gaps, hard or chalky surfaces and mastic pulling away, and note the building and elevation.
Budgets are easier to plan when sealant is part of planned maintenance. We can quote buildings in priority order so spending is spread.

What else we do in Sudbury
Your questions answered
Can work in a care setting near Sudbury go ahead while residents are there?
Yes, with the manager deciding the order and timing of rooms. Noise and disruption are kept to a minimum.
Does your area include sites such as Greenford Green Business Park, near Sudbury?
Yes. Estates, retail parks and business parks around Sudbury, Greenford Green Business Park among them, are all within reach. A few photos and the unit address let us price the work.
How long do sealant joints last?
Nobody can honestly give a figure in years, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular inspection is the best way to catch problems early.
Do you need to see the site first?
Many jobs can be quoted from photographs, drawings or a joint schedule. Where they aren’t, we arrange a site visit.
Do you supply RAMS and insurance details?
Tell us what site paperwork you need (RAMS, insurance certificate, CSCS details) and we’ll confirm with the quote. We are CHAS accredited and a Constructionline member.
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.
Do you guarantee the mastic work?
There is a 12-month guarantee on our workmanship, backed by public liability insurance.

Do you need mastic sealing in Sudbury?
Topping up old mastic is a common shortcut. New sealant won’t grip failed sealant, so these repairs rarely last.
Typical triggers for a call:
- Damaged joints in communal entrances and corridors
- Mastic failing across several blocks on an estate
- Cracked, hardened mastic round windows on a block
- Damp patches beside frames
Site managers at schools like Sudbury Primary School can fit frame mastic into the summer works.
Questions to ask before you book
- How they handle RAMS and site documents
- What level of public liability insurance do they hold?
- Will CSCS-carded applicators be on site?
- Are they CHAS accredited or on Constructionline?
