What we can’t put right
Some faults sit outside our scope, and we say so rather than covering them up:
- Failed waterproofing membranes on podiums, roofs or decks (a waterproofing specialist’s job)
- Movement on a scale no sealant is meant to absorb
- Mechanical expansion joint covers, cover plates or proprietary joint systems (a specialist supplier’s job)
Not sure which it is? You can give us a call on 01277 525 020 or use the quote form and we will tell you honestly.

Expansion joint sealing for commercial buildings in Pinner Green
Every structure moves a little, all the time: they expand in the heat, shrink as they dry, and shift under load. Expansion and movement joints are built in so the structure can move without cracking. Mastic Doctor reseals movement joints in brickwork, blockwork, concrete, cladding and floors for buildings in Pinner Green. We work on precast concrete panel joints, car park decks and ramps and brickwork movement joints, and the failures we are asked to look at most are previous reseals laid over old sealant and joints packed with grit and debris. Searching for sealant specialists in Pinner Green? We’ve been sealing commercial buildings since 2005, CHAS accredited and a Constructionline member.
Distribution and trade units on London’s edges, and deck car parks across the city, hold most of its floor and slab joints. Planning a job in Pinner Green means thinking about access, loading times and the ULEZ as well as the joints.
The 12-month guarantee covers our workmanship: the preparation, the sealing and the tooling. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

What else we do in Pinner Green
Our process
When we get to site, we report to your site contact and complete whatever induction the building runs. Floors, finishes and fittings next to the joints are covered before any cutting starts, with the work itself usually taking anything from part of a day to a couple of weeks, depending on joint lengths, widths and access. All of Greater London is in the ULEZ, and kerbside space in Pinner Green can be scarce. Let us know about any on-site parking or loading arrangements when you send the job details.
- First the joints are inspected, widths measured and the type of failure noted.
- A fixed quote names the sealant we propose and its movement class.
- Phasing is agreed so decks, floors or entrances can stay in use where needed.
- We strip the old sealant or filler and prepare each face until it’s sound and dry.
- Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
- We check each joint with you, confirm the cure time and sign off under our 12-month guarantee.
Before we start on site
- For older buildings, check the asbestos register before work
- Have the specification and drawings to hand
- Agree which areas must stay open

Advice
Traffic, movement and joints around Pinner Green
Less than 3 miles from Pinner Green there are at least three named estates and business parks. Sites like these are full of saw-cut floor joints, yard slabs and car park joints. In London, decks, bays and service yards normally have to keep running, which is why we work a few bays at a time.
Phasing is what makes joint work possible on busy sites such as Harrovian Business Village (2.6 miles south-east of Pinner Green): one bay, aisle or car park row at a time. For a centre such as St. George's Shopping Centre, 2.6 miles south-east of Pinner Green, the service yard and car park joints typically need attention first. A campus such as Westminster University, 3.4 miles to the south-east of Pinner Green, has long runs of movement joint in its buildings, decks and paving.
Pinner Green is about 2 miles north-east of Ruislip, in Greater London. Commercial clients in Pinner Green can call on us for movement joints. Pinner Green is one of 764 places in Greater London on our list for movement joints. Sites around London have their own page, about 15 miles away.
If you need expansion joint sealing in HA5 and HA6, the process matches everywhere else we work: send details, get a quote, we seal, guaranteed.

Further afield, our area takes in London (15 miles south-east), City of Westminster (12 miles south-east), Marylebone (12 miles south-east), Kensington (11 miles south-east), St Pancras (13 miles south-east) and Shoreditch (14 miles east).

Doing it in-house
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.
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, which is what makes a joint last.
How the quote is worked out
Your fixed quote is built from the real scope. It takes account of:
- Travel to remote or island sites
- How much there is to seal
- Induction, permit and paperwork requirements
- How accessible the joints are
The price depends on the quantity of joints, what has to come out first and how the joints are reached. Call for a fixed quote when you are ready.
Before you send an enquiry
Good information means a firmer quote. When you get in touch, include:
- Any dates the work must fit around
- Asbestos survey details if the building is older
- What the building is and how it’s used
- Drawings or a marked-up plan, if available
We quote a fixed sum against the scope you give us, so you know the figure before anyone is on site. To start the process, call the office on 01277 525 020 or email the details over.
Leave it or put it right?
Some quotes just add sealant over the old bead. A bead laid on top of the failed one neither grips nor flexes properly and soon lets go. We cut out the old seal and prepare the faces every time. Getting scaffold, permits or access booked in Pinner Green takes effort, so while access is arranged it pays to renew all failing joints, not just the worst.
Larger quantities, tricky access or phasing all shape the price. Site requirements like inductions and permits play a part as well.

Common questions from Pinner Green clients
Would you work within a site like Northwood and Pinner Cottage Hospital?
Yes, hospitals are one of the sectors we cover. The estates team’s permit system and infection-control rules come first, and the work is planned around them.
Will you take on work at estates like Waverley Industrial Park, close to Pinner Green?
Yes. Our area takes in Pinner Green and its surroundings, with estates and business parks such as Waverley Industrial Park included. To start, just speak to us on 01277 525 020 or email drawings and photos with the unit, the joints involved and your access times.
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.
Will you quote for a small job?
We quote for single jobs as well as large packages and programmes. Send details for a fixed quote.
Can you handle several sites?
Yes. A group of buildings can go on one quote, and you deal with one contact throughout across South East England, Greater London and Scotland.
Can you follow the specification on our project?
Yes. Send it with your enquiry, and we will price the work to it, flagging anything that needs clarifying.
Do the joint edges need to be sound before sealing?
A bond is only as strong as the material behind it, so broken or crumbling edges have to be repaired first. We flag it at the quote stage where we can see it.
Aftercare for building managers
After handover, these steps help:
- Keep racking legs and heavy point loads off floor joints
- Report split or peeling joint sealant early
- Put movement joints on the planned maintenance inspection round
- Brief car park operatives to protect joint lines during winter clearance
Keep wheels, feet and water off new joints until the sealant has cured. How long that takes depends on the product, the temperature and the depth of the joint, and we confirm it for each area before we leave. Barriers left in place until then protect the finish.
Floor joints with failed fillers break up quickly under wheels. Damaged edges make the floor rough and wear wheels faster and the broken length grows with every pass. Sealing early protects the edges.
