Honest limits
Some faults sit outside our scope, and we point that out rather than sealing over them:
- Movement on a scale no sealant is meant to absorb
- Concrete or masonry repairs along the arrises
- Leaks coming from the membrane rather than the joint seal
If in doubt, phone 01277 525 020 or email drawings and photos and we will say what we think.

Expansion joint sealing in Neasden
Mastic Doctor has sealed movement joints since 2005, for main contractors, FMs, managing agents and building owners. 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 car park decks and ramps, cladding panel joints and blockwork control joints, and the usual reasons a site gets in touch are new sealant over old, now failing and damp inside where a wall movement joint has failed. Whether you call it commercial sealant work, mastic application or joint sealing, in Neasden it comes down to the same thing: failed joints cut out, faces prepared and the right sealant laid to the right depth.
Floor and movement joints in London take heavy use: car park decks, loading bays, shopping centre malls and podiums over occupied space. A failed joint lets water and debris in, and the edges soon spall.
What our 12-month guarantee covers is the way we did the job: preparation, application and finish. It doesn’t extend to damage, other trades’ later work or movement the joint was never designed to take.

What else we do in Neasden
Keeping the joints sound
Your facilities or cleaning team can help the joints last. Share these points with them:
- Clear dirt from joint lines during routine cleaning
- Avoid parking heavy plant or pallets on joint lines
- Record the sealant used and the date in the O&M file
- Look over external and deck joints after a hard winter
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.
When one joint fails, others of the same age are rarely far behind. It pays to check every joint, not just the obvious one, so the work can be planned rather than rushed. We will tell you which movement joints need doing now and which can wait.
Site staff or a sealant specialist?
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist brings efficiency, a consistent finish and a 12-month guarantee.
Redoing a failed joint usually costs more than getting it right at the outset, 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.
Work for main contractors and building owners
Hotels, schools, healthcare sites, offices and retail units come to us directly as well. We plan around the way the building is used, so the building keeps working while we do.
We work for building owners and managing agents on everything from one building to a spread of sites. One quote can cover more than one site, so there’s one set of paperwork to deal with.
Your questions answered
Do you work in London buildings with loading restrictions?
Yes. Inductions, permits and timed loading are routine for us in London. The building manager’s rules go straight into our method. We allow for the ULEZ, which covers every borough
Will you take on work at estates like Falcon Park Industrial Estate, close to Neasden?
Yes. Our area takes in Neasden and its surroundings, with estates and business parks such as Falcon Park Industrial Estate included. A few photographs and the unit address let us price the work.
Does the weather affect joint sealing?
A wet joint can’t be sealed properly so we’d rather rearrange than seal in the rain. We agree a revised date with you.
Can you seal car park deck joints?
Yes. Tyre loads, grit and de-icing salts make these some of the hardest joints to keep sealed, and we’ll tell you if any edges need repairing first.
Do you offer coloured sealant?
It depends on the product specified. Some ranges offer many colours, others very few, so we’ll confirm the colours available for the specified product with the quote.
What guarantee do you give on joint sealing?
The workmanship is guaranteed for 12 months from sign-off, and we are fully insured for public liability. Keeping joints clear of debris helps them last.
Do you seal on top of existing sealant?
No. We cut the old material out and clean the joint back before sealing, since fresh sealant will not bond reliably to aged material.
What happens if it’s left?
Closing a car park for a reseal is rarely an option. Phased work by bay or zone lets the rest stay in use, compared with a full closure. We agree phasing with you before work starts. In a London building, a failed joint rarely affects only one party. Putting it right early is less disruptive than dealing with the consequences.
There’s no price list, 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.

From enquiry to sign-off
Where the site stays busy, we agree a sequence with your contact so the disruption stays in one area at once. Each area is protected, prepared and sealed before we move to the next. The ULEZ covers the whole of Greater London, and parking near a job is rarely simple. Let us know about any on-site parking or loading arrangements when you send the job details.
- We start with photos, approximate lengths and any drawings, visiting where needed.
- Joint widths and expected movement are checked against what the sealant can take.
- Old sealant and debris are cut out of every joint.
- Edges are checked, and we tell you if any need repairing before sealing.
- The right sealant goes in at the right depth, bonded to the two sides only.
- Areas reopen once cured, and the work carries our 12-month guarantee.
Preparing the site
- Clear stock, furniture or equipment away from the joints
- Share your working hours and any access restrictions
- Send any specification or drawings in advance
