Owners, agents and contractors
For main contractors, we work as the sealant subcontractor on new-build and refurbishment projects. We work to your programme, your specification and your site rules.
Hotels, schools, healthcare sites, offices and retail units book us directly too. The work is planned around how the building runs, so the building keeps working while we do.
Expansion joint sealing for commercial buildings in Crookham
Our movement joint work takes in walls, panels, decks and floors: brickwork and blockwork joints, precast and cladding panel joints, concrete joints, car park decks and ramps, podiums and floor movement joints. The product depends on the movement, the weather and anything that runs over it, and we’ll confirm the choice in the quote. The enquiries we see most involve leaks through car park deck joints onto the level below and expansion joints filled with dirt and stones, across car park decks and ramps, cladding panel joints and blockwork control joints. Whoever orders the work in Crookham, the brief is normally the same: a fixed quote, no surprises on site and a 12-month guarantee behind the result.
Smaller community and commercial buildings around Crookham have their own movement joints in walls and floors. They tend to be overlooked until something leaks or cracks.
Every job we finish is backed by a 12-month workmanship guarantee. If a joint we sealed fails because of how it was installed, we come back and put it right.

Your questions answered
Can you work at a site such as Colthrop Industrial Estate, by Crookham?
Yes. We cover Crookham and the area around it, including industrial estates, business parks and retail parks such as Colthrop Industrial Estate. Photos and a short description are enough for a first look.
Would you work within a site like West Berkshire Community Hospital?
Yes. We work in healthcare settings as well as offices and schools. Work is phased so departments keep running, under the site’s own rules.
Do you have public liability insurance?
Yes. Mastic Doctor is fully insured, public liability included.
Do you need to see the site first?
It depends on the job. Straightforward work can often be priced from photographs and measurements, and bigger or more complex jobs typically get a visit.
Can the building stay open while you work?
Normally, yes. We phase the work so most of the building stays in use, with each area protected and signed.
How long do sealant joints last?
There isn’t a single answer, because life depends on how much the joint moves, how exposed it is and how it’s cleaned and used. Regular checks let you plan resealing before leaks or damage.
Can you fit around our working hours?
Give us your site hours and any access windows in your enquiry, and we will schedule the work to suit. You can reach the office between 8am and 5pm, Monday to Friday.
Site staff or a sealant specialist?
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. A poor seal in places like these tends to cost more to put right later.
For most general trades, sealant is a sideline. A specialist brings correct preparation, depth control with backing rod and a product suited to that particular joint.
Warehouse floors and decks around Crookham
Crookham sits in one of the drier corners of the country, the South East. Outside joints in yards and car parks still have to be dry before sealing, and winter de-icing salt on car parks and ramps works into any open joint. Less than 3 miles from Crookham there are at least three named estates and business parks. Their warehouses, yards and car parks are exactly where joints take the most punishment.
Hospital campuses such as West Berkshire Community Hospital, 3.8 miles to the north-west of Crookham, grow in stages, leaving movement joints wherever new blocks meet old. Schools like Brimpton C.E. Primary School often have long brick elevations with movement joints that age quietly. At places like Scion Business Park, which lies south-east of Crookham, joints are sealed a section at a time so operations carry on.

Other landmarks nearby include Old Chapel Textile Centre (2.7 miles west) and West Berkshire Community Hospital (3.8 miles north-west). Green spaces nearby include Thatcham Reed Beds.
After the work
Problems stay small when the joints are checked regularly. Specifically:
- Reopen bays and walkways only after the stated cure time
- Keep stones and debris out of open joint lines
- Report split or peeling joint sealant early
- Inspect movement joints alongside other routine building checks
Add every elevation, deck and floor joint to your inspection round. Early splits and edges starting to lift show up on a routine check, when they’re still cheap to deal with. If anything looks wrong, speak to us on 01277 525 020 or use the quote form with photos.
Rain gets into walls through torn brick and block movement joints. It can surface inside as damp a long way from the joint. Resealing promptly prevents internal damage.
What sets the cost
Each job is priced on its own details. The things that drive the figure:
- Quantities, in metres or numbers
- Any access equipment needed
- Specialist products, such as fire-rated or hygienic sealants
- Location, for remote and island sites
Cost follows what’s involved: stripping out, preparation, sealing, access and phasing. Call for a quote.
Before you send an enquiry
Diagnosis starts before we arrive. Let us know:
- When you need the work done

- Approximate linear metres or a joint schedule
For a fixed quote, speak to us on 01277 525 020 or email a schedule or drawings with the site address and an outline of the work. Our quote form is another easy route.
Why deal with it now?
Leaving a failed movement joint rarely stays a small problem. Water and debris get in, the joint jams and the edges spall, so a reseal turns into an edge repair as well. Resealing early keeps the work to sealant. Halls, stores and units around places like Crookham may not be checked every day, so a failed joint can leak for a while before anyone sees it. Resealing early avoids that.
What a job costs comes down to how many linear metres there are, how much old material needs removing and how the joints are reached. Call for a fixed quote when you’re ready.

On site: what to expect
At the end of each section, the masking comes off, the area is cleaned and every joint is checked with your site contact. If an area should be left alone while the sealant cures, we say how long and put signs out. Jobs in and around smaller places like Crookham are typically planned as a single visit, so photographs and measurements up front really help. That way the right products come on the day.
- We assess the joints on site or from photographs, noting widths and how each has failed.
- 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.
- The failed seal is cut out and both joint faces cleaned back to sound material.
- Backing rod or bond-breaker sets the depth, primer goes on where specified, and the sealant is applied and tooled.
- Finished joints are inspected, the cure time confirmed and the 12-month guarantee applies.
What we need from you
- Arrange parking or a loading space
- Clear stock, furniture or equipment away from the joints
- Warn occupants and staff about the work
