Bert And Mary Supply in Baltimore: Materials and Tools for Masonry and Concrete Work

Bert And Mary Supply is a contractor-focused distributor of masonry and concrete materials, equipment rental, and tools located in Baltimore. The business serves professional masons, concrete finishers, and serious DIYers who need to source supplies locally rather than wait for delivery or settle for big-box inventory gaps.

What Bert And Mary Supply Actually Is

This is a trade supplier, not a retail showroom. The inventory focuses on the materials masons and concrete contractors need daily: Portland cement, sand, gravel, concrete admixtures, masonry anchors, mortar colorants, and finishing tools. The operation includes an equipment rental section where contractors can rent mixers, concrete saws, and vibrating screeds by the day or week. Unlike home improvement chains, staff here understand jobsite needs and can recommend material grades, quantities, and substitutions based on specific project conditions rather than pushing standard packages.

Materials, Equipment, and Pricing

Bulk cement and sand are priced by the bag and by the ton. Standard Portland cement runs roughly $10 to $14 per bag depending on quantity and current market prices (verify current rates by calling ahead, as cement costs fluctuate). Pre-bagged mortar mixes range from $6 to $10 per bag. Specialty products like self-consolidating concrete, fiber-reinforced mixes, and masonry colorants carry premiums of 15 to 40 percent over standard formulations.

Equipment rental begins at roughly $40 to $75 per day for hand tools and portable mixers. Concrete saws and larger equipment rent for $80 to $150 daily. Weekly rates typically discount by 20 to 30 percent compared to daily pricing. Deposits and damage waivers apply to all equipment.

The competitive advantage over big-box retailers is depth in specialty grades: they stock high-early-strength cement for cold-weather pours, air-entraining admixtures for freeze-thaw durability, and extended product lines of tints and accelerators. Home Depot and Lowe's carry the basics but rarely stock the full range or can answer technical questions about mix design or application conditions.

How It Compares to Other Baltimore Options

Masonry supply in Baltimore is fragmented between this type of trade distributor, national big-box chains, and a few smaller independent yards. Home Depot and Lowe's offer convenience and lower per-unit prices on commodity items like bags of standard concrete mix, but they don't rent equipment, don't stock contractor-grade materials in volume, and employ staff without trade knowledge. If you need 40 bags of cement delivered to a job site or a concrete mixer for three days, Bert And Mary Supply will outpace a retail visit. If you need one bag of concrete mix for a mailbox repair, the big box is faster.

National suppliers like Concrete Pumping Services operate in the region but focus on large-scale delivery and pumping services, not retail sales or rental. Bert And Mary Supply fills the gap for contractors and homeowners who want to buy and haul materials themselves.

Who It Suits and Who It Does Not

This is the right stop for licensed masons, concrete contractors, and property owners undertaking substantial masonry or concrete work (patios, walkways, retaining walls, brick repair). It suits people who can evaluate their own material needs or work from a contractor's specifications. It does not suit someone making a single small repair who just needs generic "concrete mix" or someone who prefers not to transport bags or equipment themselves.

What the First Visit Involves

Call ahead with your project details (scope, square footage, concrete strength needed, timeline). Staff will recommend material type, quantity, and any admixtures or finishes. For equipment rental, bring a valid ID and be prepared to sign a rental agreement. Expect to load and transport materials yourself unless you arrange delivery separately. Many contractors call in orders and pick them up the same day.

Hours, Location, and Logistics

Verify current hours and location by phone before visiting, as trade suppliers sometimes adjust schedules seasonally or for inventory. Most supply yards operate Monday through Friday during standard business hours and close or reduce hours on weekends. Parking and loading areas are typically separate from retail space, allowing contractors to back up and load without blocking pedestrian traffic. Call to confirm whether delivery is available and at what cost threshold.

Bert And Mary Supply serves Baltimore's active construction community because it stocks what professionals actually use and prices materials competitively enough that buying locally beats waiting for mail order or overpaying at retail chains.
