Kelemer Brothers Replacement Windows in Baltimore: Energy-Efficient Upgrades for Older Homes
Kelemer Brothers is a Baltimore-based window replacement contractor specializing in retrofitting older rowhouses and Victorian properties with modern double-hung and casement windows. The company operates as a licensed, family-owned installer serving the metropolitan area for residential projects ranging from single-window repairs to whole-house replacements.
What Kelemer Brothers Actually Does
Kelemer Brothers handles window measurement, fabrication, installation, and finishing work on existing homes. The company does not manufacture windows but sources from established suppliers and installs them as a turnkey service. Work centers on replacing original single-pane or deteriorated double-pane windows with new units that meet current building code and energy standards. The company also performs storm window installation and repairs to existing frames and sills.
Services and Pricing
Replacement windows through Kelemer Brothers typically cost between $400 and $800 per window installed, depending on size, material (vinyl vs. wood-clad), and frame condition. A standard replacement in a Baltimore rowhouse (replacing ten to fifteen windows) falls in the $5,000 to $10,000 range before incentives.
The company offers vinyl-frame windows with Low-E glass (reduces heat loss in winter and summer heat gain) and wood-clad exterior options for homes where aesthetic preservation matters. Installation includes removal of the old sash, frame preparation, new unit setting, insulation, caulking, and interior/exterior trim finishing. Storm window installation runs $150 to $300 per unit.
Kelemer Brothers participates in the Maryland Home Energy Loan Program and can direct homeowners to available state and federal rebates for energy-efficient windows, which can reduce out-of-pocket costs by 10 to 20 percent depending on household income and project scope. Confirm current rebate eligibility and amounts with the company, as state programs adjust seasonally.
How It Compares Locally
Kelemer Brothers competes primarily with larger regional chains like Renewal by Andersen and Pella, which operate showrooms in the Baltimore area and typically charge $600 to $1,200 per window installed due to corporate overhead and marketing costs. Those companies offer more extensive warranty packages and operate call centers; response times are often slower for small jobs.
Local independent installers like Chesapeake Window & Door (based in Dundalk) and smaller contractors operate at similar price points to Kelemer Brothers but often lack formal participation in state rebate programs and may not carry the same product depth.
Choose Kelemer Brothers if you want a mid-range local contractor with direct access to ownership, straightforward pricing, and familiarity with Baltimore's housing stock. Choose a regional chain if you prioritize a national warranty and prefer a corporate service structure, or if you need work completed within two weeks and flexibility is less important than guaranteed availability.
Who It Suits and Who It Does Not
Kelemer Brothers suits Baltimore homeowners with 10 to 40-year-old windows experiencing condensation, drafts, or operational failure, and those interested in energy savings without a large custom-fabrication budget. The company is a fit for owners of row houses, brick colonials, and mid-century homes where window replacement is part of a longer renovation.
It is not the right choice for historic properties requiring restoration-grade wood windows or custom divided-light designs (those need specialized restoration shops), for commercial or rental property owners managing dozens of units at once, or for households prioritizing the fastest possible turnaround time.
What the First Visit Involves
Kelemer Brothers typically begins with an in-home measurement and assessment. A representative will examine the existing windows, frame condition, and any water damage or rot, then provide a written estimate specifying window type, material, quantity, labor, and applicable discounts.
The company requires a deposit (customarily 25 to 50 percent of the estimate) to order windows. Lead time between order and installation ranges from two to four weeks depending on window availability and the installer schedule. Installation typically takes one to three days for a full-house job.
Hours, Parking, and Logistics
Kelemer Brothers operates Monday through Friday, 8 a.m. to 5 p.m., with Saturday appointments available by request. The company is based in Baltimore proper and serves the city and surrounding counties. On-site parking during installation is the homeowner's responsibility; the crew typically uses one or two vehicles.
Contact the company directly to confirm current lead times and to verify whether any seasonal promotions or rebate programs are active at the time of your inquiry.
Kelemer Brothers fills a practical niche for Baltimore homeowners: local enough to understand the city's architectural constraints, established enough to manage rebate paperwork, and priced competitively for a region where window replacement is a routine home investment.
