Welcome to Hamulack Electric. I am Matt Hamulack, a licensed Master Electrician, who does residential electrical work in the MD and PA areas. My mission is to provide competent electrical work for homeowners at a fair price. With many years of experience working for Seufort Electric, Electrico and University of Baltimore doing commercial electrical work, I knew that starting my own company would give me the freedom to do what I love: helping homeowners handle all of their electrical needs, big and small. From Panel Upgrades, to basic wiring for outlets and switches, there's no problem I can't solve.

"Matt was timely, courteous and a great diagonostician. I will use him certainly for next time hubby tries to tackle another ambitious electrical project!! Lol"

"We bought a new construction and McCrea installed the HVAC. Home inspection identified the heat pump was not working in Oct. 2020. McCrea identified it was due to leaking refrigerants and promise fixed the issue. Our electric bill was extremely high the following two months and the heat pump was not cooling in Spring 2021. McCrea sent technician and again repaired the system. Bought their maintenance plan. We had 4+ repairs plus regular tune up in the past two years. Last week the heat pump stopped cooling again. We are out of labor warranty and charge us with $89 diagnostic cost after membership discount. It took three days for them to send someone to check while we suffering 90F in our house. They identified the compressor dead and need replacement. They charge $1900 for labor after membership discount. Most likely cause of the compressor failure is "suicide" with assistance. Low refrigerant at beginning and over change in later repairs likely contributed the short life."

Subcontractors questions, answered by experts

Modular homes are more affordable than stick-built homes if you keep quality and square footage equal. The cost to build a home averages $323,000, while average modular home prices sit at {AvgCost}. If you’re looking for custom or luxury options, a traditional custom home costs $825,000, while a high-end modular home costs $600,000, on average.

There are several different steps in the pole barn building process. First, you’ll need construction plans, which you’ll use to obtain permits. Then, you can clear the land so it’s suitable for building and installing the foundation. Your contractor will frame the barn using large poles, then rough in the plumbing and electricity (if your barn has those elements) before finishing the interior, adding siding, and installing the roof. 

After that, they’ll finish up the electrical work and plumbing and add your windows and doors. You may have a few other finishing jobs to do like painting or waterproofing.

General contractors typically manage home renovation or build projects that last more than a week and involve various skilled tradespeople. Some examples include building a new home or barn, adding an extension or garage, or carrying out major room remodels involving extensive plumbing, electrical, and structural changes.

It pays to hire a project manager or general contractor when you have a large-scale project that will take over a week to complete, especially when it involves structural changes and multiple subcontractors. This includes hiring a general contractor to build a house, add an extension, or manage other projects that need a building permit.

Painting countertops can take a few days to complete yourself. However, keep in mind that it can take up to 14 days for the sealer to cure. So, you want to make sure you wait the manufacturer's recommended amount of time before using your countertops after painting them.
