Questions about Petersham
Does your area include sites such as St. George's Industrial Estate, near Petersham?
Yes, sites like St. George's Industrial Estate are within our area, along with the rest of Petersham. To start, just speak to us on 01277 525 020 or send photos by email with the unit, the joints involved and your access times.
Do you take on jobs in Petersham where loading and access are tightly controlled?
Yes. Booked loading bays, goods lifts and permit-to-work systems are normal for London jobs. Say when the building is occupied and when it’s quiet, and we will plan accordingly. The ULEZ covers the whole of Greater London, which we allow for
Do you work in Petersham?
Yes. Sites across Petersham are covered, and the same phone number covers every area.
Are you CHAS accredited and on Constructionline?
Yes. We are CHAS accredited and a Constructionline member, which helps with supplier vetting.
Do you take on multi-site work?
Yes. We take on portfolio and planned maintenance work, with each site phased to suit its occupants.
Can you work while the building is occupied?
Yes, as long as we plan it. We agree a sequence with your contact so just one area at a time is disrupted.
How do you deal with asbestos in old sealant?
Some older mastics, especially in pre-2000 buildings, can contain asbestos. We check the asbestos register before cutting out old sealant in an older building, and if asbestos is suspected, work stops until it’s tested. We don’t remove asbestos-containing materials.
How we handle expansion joint sealing in Petersham
Buildings and slabs are never completely still: temperature, moisture, shrinkage and loading all make materials grow and shrink. Expansion and movement joints are built in so the structure can move without cracking and the seal across each one keeps out water and grit. Mastic Doctor reseals movement joints in brickwork, blockwork, concrete, cladding and floors. We work on brickwork movement joints, podiums and floor movement joints and blockwork control joints, and the failures we are asked to look at most are hardened, cracked sealant on exposed facades and damp inside where a wall movement joint has failed. A specialist sealant contractor works differently from a general builder: on jobs in Petersham, preparation and product choice get the time they need.
Areas such as a loading bay or car park deck in Petersham usually have to stay in use. We work through joints a section at a time, closing small areas in turn, at times agreed with the building manager.
Every job we finish is backed by a 12-month workmanship guarantee, wherever the site is. If our installation lets you down in that time, we return and fix it.

Expansion joint sealing around Petersham: points for this area

Less than 3 miles from Petersham there are at least three named estates and business parks. That puts plenty of warehouse floors, service yards and car parks close by, all with joints under traffic.
For a centre such as Ivybridge Retail Park (1.5 miles north-west of Petersham), the service yard and car park joints normally need attention first. University campuses such as St Mary's University (1.5 miles south-west of Petersham) have car parks, paved walkways and building elevations with movement joints.

After the work
After handover, a little attention goes a long way:
- Plan racking layouts so feet don’t land on a joint
- Raise snow-clearing blades over deck joints where possible
- Keep traffic off new joints until the cure time is up
- Look over external and deck joints after a hard winter
Debris does more harm to joint sealant than most people realise. Grit trodden or driven into the joint works at the surface until it tears and decks and floors suffer most. Regular sweeping keeps joint lines clear.
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.
Our process
Occupied buildings need a little choreography. We sign and contain the area we are in, with routes through the building left open and move on in phases so staff and visitors can carry on around us. In Petersham, most buildings stay in use during the work, so zones and timings are agreed with whoever manages the building. Phased work keeps the rest of the building in use.
- Photos, joint lengths and drawings come to us, or we visit.
- We compare each joint’s width with the movement and the sealant’s capability and tell you if the design looks wrong for the movement.
- Every joint is cleared of the failed seal and any grit packed into it.
- Any broken arrises or friable edges are flagged before work goes further.
- 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
- Point out any areas we must not close
- Make sure the joints can be reached
- Send any specification or drawings in advance

What affects the price in Petersham
Quotes vary with the job. It mainly depends on:
- Travel to remote or island sites
- Specialist products, such as fire-rated or hygienic sealants
- How much existing material needs removing
- The total length or number of joints
Every site prices differently: joint size, product, access and site hours all play a part. A fixed quote follows once we understand the job.
Before you send an enquiry
A good diagnosis starts with the right details. Tell us:
- Where the site is, with the postcode
- Asbestos survey details if the building is older
- The type of building and who uses it
- Rough lengths or quantities, or drawings if you have them
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.
Surface by surface
Concrete and precast panel joints
Precast and concrete panel joints move daily. We use a sealant classed for the movement, laid over backing to depth.
Car park decks and ramps
Failed deck joints often show as leaks on the level below. The old seal comes out, the edges are prepared and the joint resealed.
Signs you need expansion joint sealing in Petersham
Some joints were never sealed with the right product. Products not classed for the movement fail early. BS EN ISO 11600 classifies building sealants by movement capability, and specifications often refer to it.
Look out for the following:
- Water getting into the wall through a failed joint
- Car park joints leaking onto vehicles below
- Arrises breaking up along floor joints
- Torn sealant in brick or block movement joints
Another example is Newmans Shipyard & Business Park, which lies west of Petersham, where floors and yards would be done in stages around the occupiers.
Before you book anyone
- Their plan for phasing and protecting the area
- Will failed sealant be removed rather than covered?
- Do they follow the manufacturer’s priming guidance?
- How they handle RAMS and site documents
Why deal with it now?
A torn seal left alone normally gets worse. Water and debris get in, the joint jams and the edges spall, so a reseal turns into an edge repair as well. Acting at the first split keeps the cost down. In a London building, a failed joint rarely affects only one party. Dealing with it early is simpler for everyone.
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a fixed quote.
