Maintenance after handover
Your facilities or cleaning team can help the joints last. Share these points with them:
- Keep stones and debris out of open joint lines
- Record the sealant used and the date in the O&M file
- Reopen bays and walkways only after the stated cure time
- Look over external and deck joints after a hard winter
Every joint we seal is backed by a 12-month guarantee on workmanship. Record which product went into which joints in the building file.
Once debris packs a failed joint, the structure has nowhere to expand. The edges then take the pressure and start to spall, turning a sealant job into a repair job. A sound seal keeps the joint working.
Expansion joint sealing in Stroud
Long runs of brick or block have movement joints built in. Once the seal fails, rain reaches the cavity and the joint can no longer close. The old seal comes out, backing goes in and a sealant with the right movement class is applied, primed where the manufacturer specifies. The enquiries we see most involve brittle, chalky sealant on external joints and arrises breaking up along floor joints, across podiums and floor movement joints, blockwork control joints and car park decks and ramps. Most enquiries from Stroud start with one failed joint and grow into a wider look at the building: we check the joints around it and give you an honest view of what needs doing now and what can wait.
Around smaller places such as Stroud, floor joints are often in barns and farm buildings turned into workshops, stores and offices. Whether it’s a farm store turned workshop or a storage unit, the joints need a product that suits the traffic.
What our 12-month guarantee covers is the way we did the job: the preparation, the sealing and the tooling. Damage, later alterations by others and movement beyond what the joint was designed for sit outside it.

General trades versus a specialist
For a quick touch-up, site staff may be fine, but larger jobs are different: a specialist works through quantities efficiently, leaves a consistent finish and backs it with a 12-month guarantee.
Some joints are best left to specialists: for instance fire-rated seals that must match a tested detail, trafficked floor joints and external movement joints. Getting these wrong typically costs more in the end than doing them right.
Signs you need expansion joint sealing in Stroud
When the movement exceeds the sealant’s capability, the bead tears. A joint that’s too narrow for the movement, or a product with the wrong movement class, will split through the middle. Resealing like for like often fails the same way.
Most enquiries start with one or more of the following:
- Rain penetration at brick or block movement joints
- Sealant pulling off the joint face
- Brittle, chalky sealant on external joints
- Joints packed with grit and debris
For an estate such as Petersfield Hospital, 1.3 miles to the east of Stroud, the joints in ramps, decks and long building elevations all need attention over time.
Questions to ask before you book
- Which product they’ll use, and why it suits the joint

Common questions from Stroud clients
Does a site in Stroud have to shut while its joints are sealed?
In most cases the site keeps working. Joints are done in phases, a bay, aisle or deck at a time. The phasing plan comes with the quote.
Is Stroud too far out for you?
No. Places such as Stroud are covered as much as the big towns. London and every South East county are within our area. We plan jobs in smaller places so return trips are kept to a minimum.
Are you CHAS accredited and on Constructionline?
Yes. Mastic Doctor is CHAS accredited and a Constructionline member.
How do we ask for a quote?
There are four steps: send details, receive a fixed quote, we carry out the work, and it’s guaranteed. The first step only needs photographs and a postcode.
Will you come and look before quoting?
It depends on the job. Simple work can often be priced from photos, while larger or less clear jobs get a site visit first.
Can one quote cover more than one building?
Yes. Several buildings can share a single quote, and you deal with one contact throughout.
When can you be on site?
The office is staffed Monday to Friday, from 8am until 5pm. Let us know your site hours and access windows, and the work will be planned around them.
Slabs, ramps and loading bays in Stroud
Rainfall across the South East, Stroud included, is lower than in many parts of the UK. Outside joints in yards and car parks still have to be dry before sealing, while winter salting gets into any joint left open. At about 51 miles from central London, Stroud is within reach of the capital. The South East has large numbers of industrial estates and warehouses along the motorway corridors, and their floor joints take forklift and pallet-truck traffic all day.
Schools like Langrish Primary School often have long brick elevations with movement joints that age quietly.

What affects the price in Stroud
Sealant work doesn’t have a standard rate, because every site is different. What we look at:
- Whether old sealant has to be cut out first
- Which sealant the job calls for
- The site’s rules and procedures
- Location, for remote and island sites
We don’t publish prices, because the scope varies so much from one building to the next. For a fixed figure, call for a quote and we will price your job on its own details.

On site: what to expect
Site rules come first: signing in, inductions and any permit to work. Once we are cleared to begin, we take the joints in the sequence agreed with you. Rural sites near Stroud may need directions, gate codes or a contact on site. Add it to your enquiry and we’ll build it into the plan.
- We look at the joints, their width and how they’ve failed.
- You get a fixed quote with the product and its movement capability stated.
- Old sealant and filler are cut out and the joint faces cleaned back to sound material.
- Backing rod goes in at the right depth, or bond-breaker tape where the joint is shallow.
- Primer goes on where the manufacturer specifies it, followed by the sealant, which is then tooled off.
- Each joint is inspected and handed over with our 12-month guarantee.

Advice
How the job changes by surface
Cladding panel joints
Metal and composite panels shift considerably as temperatures change. The joints need a low-modulus sealant with enough movement capability in a colour confirmed for that product.
Podium joints
On podiums, the joint can belong to a larger waterproofing detail. We reseal the joint where sealant is the specified fix, and tell you if the problem looks like the waterproofing below.
