Expansion joint sealing for commercial buildings in Nash Street
Mastic Doctor has sealed movement joints since 2005. CHAS accredited, Constructionline member, CSCS-carded applicators and five million pounds of public liability insurance. Workmanship is backed by our 12-month guarantee. We work on cladding panel joints, blockwork control joints and precast concrete panel joints, and the failures we’re asked to look at most are expansion joints filled with dirt and stones and water dripping through deck or ramp joints. For commercial sealant work in Nash Street, you deal with one contact from quote to sign-off, for single jobs and planned programmes alike.
Halls, schools and small commercial buildings near places like Nash Street have movement joints in brick, block and concrete too. They tend to be overlooked until something leaks or cracks.

What sets the cost
Before we quote, we look at:
- Distance, for remote addresses
- How much existing material needs removing
- Quantities, in metres or numbers
- Induction, permit and paperwork requirements
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.
Before you send an enquiry
To price the job accurately, we need to understand the site. Send us:
- Any dates the work must fit around
- Approximate linear metres or a joint schedule
- A wide shot and a close-up of the area
- What the building is and how it’s used
A good quote starts with a clear picture: what’s there, how much of it, how we reach it and what’s specified. Share whatever details you have and we’ll fill any gaps with a visit.
Should maintenance staff do it?
Using site staff can make sense for a small touch-up, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
There’s also the paperwork. Many sites expect CSCS cards, RAMS and proof of insurance, and our CSCS-carded applicators are used to working under those rules.
When it isn’t the sealant
Sealant solves a lot, but not everything, and we’d rather tell you before you spend money. These need a different solution:
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
- Joints too narrow for the movement, which need redesigning by the engineer
- Movement on a scale no sealant is meant to absorb
Not sure which it is? You can call the office on 01277 525 020 or email the details over and we will tell you honestly.

Questions we are asked in Nash Street
Is a smaller place like Nash Street outside your area?
Not at all. Nash Street is within our area. Our area covers London and the South East counties. Send photographs and a list of what needs doing, and we’ll plan the job to need as few trips as possible.
Can you work on a hospital site such as Gravesham Community Hospital?
Yes, provided the work is planned with the site’s estates team. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
What about RAMS and site documents?
Each site asks for different documents, so tell us what you need and we will confirm it when we quote.
Do you work to architects’ specifications?
Yes. Include it with the drawings when you ask for a quote, and the quote will be based on it, flagging anything that needs clarifying.
Can you fit around our working hours?
Mention the site’s hours and access windows in your enquiry, and we’ll plan around them. You can reach the office between 8am and 5pm, Monday to Friday.
Can you handle several sites?
Yes. A group of buildings can go on one quote, and you deal with one contact throughout.
Which sealant will you use?
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.
Surface by surface
Internal floor movement joints
Wheeled traffic chips floor joint edges that aren’t supported. The right filler or sealant for the traffic and movement protects them.
Brickwork and blockwork joints
Masonry faces are often porous, dusty or crumbly. Faces are prepared and primed wherever the sealant maker calls for it, then seal and tool the joint.

Rainfall across the South East, Nash Street included, is lower than in many parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, and gritting in cold spells finds its way into open joints. Central London is about 21 miles from Nash Street. Warehousing clusters around the motorways that ring and radiate from London.
Across sites such as Fawkham Business Park, which lies west of Nash Street, floor and movement joints can be sealed in phases so units keep working. Campuses like University of Greenwich, 4.9 miles to the north-west of Nash Street, mix old and new buildings, with movement joints wherever they meet. In a school such as Istead Rise Primary School, movement joints in brick, block and hall floors tend to be forgotten until they leak.

Keeping the joints sound
Once the work is signed off, these steps help:
- Check joints after long freezing spells
- Clear dirt from joint lines during routine cleaning
- Keep racking legs and heavy point loads off floor joints
- Record the sealant used and the date in the O&M file
Our workmanship on movement joints carries a 12-month guarantee. Keep the handover details, product and date with your O&M records.
An open joint fills with grit, and a joint full of grit can’t close. The arrises crack and break away under the load, turning a sealant job into a repair job. A sound seal keeps the joint working.
Diagnose, treat, sign off
A typical day starts with protection: masking tape along the joint edges and sheeting over anything nearby. On site, the work typically takes anything from part of a day to a couple of weeks, depending on joint lengths, widths and access, and our waste is bagged and taken away as we go. Smaller jobs around Nash Street can be grouped with others nearby. You will have a fixed quote before work starts.
- The first job is to check each joint: how wide it is, how it moves and why the old seal let go.
- You get a fixed quote with the product and its movement capability stated.
- The failed seal is removed and both faces are cleaned until sound and dry, flagging any broken edges that need repair before sealing.
