Dave comes from a big family so he understands money and time constraints plus he wants his projects to look as aesthetically pleasing to his clients as possible. We would definitely hire Dave again."

Architecture is a collaborative process between the owner, architect and any other interested individuals. All ideas are welcome and explored thoroughly. The ideal solution is often created from a mix of all of these ideas. What I Do I believe that by working together we can create something wonderful. Something that neither you nor I could ever conceive of on our own. Such is the power of the collaborative spirit. It all begins by LISTENING! Your ideas have probably been percolating in your head for a while. It will take some serious listening on my part to retrieve those ideas and begin to turn them into a built form. The process continues with numerous meetings to further refine these ideas and concepts until we reach a point when we say, "Hey, that's it!" "That's what I've always dreamed of." Then my task is to create the necessary documents to ensure that you end up with a code-compliant, strong, technically sound structure which will enrich your life for many years. I will follow the construction through until completion. We will gaze in wonder at the beauty of this new creation.

My name is Tom Mull of Mull Bros. Oil, a family-owned heating and cooling company in Wethersfield, Connecticut, where I was born and raised. There’s no doubt that you have seen many changes with the heating oil industry in the past decade or so. While many companies have given up or, out of desperation, have changed their business philosophies, we intend to be here for a long time. As a matter of fact, we’ve been around for over 60 years. My father, Bill Mull, started this company in 1945. At a time when stove-oil was in great demand and #2 fuel was being introduced as a home-heating fuel, Bill decided to get in to the delivery business. In the early 1950’s many oil burners were being installed on coal furnaces. Being mechanically inclined, Bill learned the art of installing and servicing the many styles of oil burners and heating systems.

"After interviewing several companies and getting quotes, we were most convinced of the combination of quality and value offered by Mull Brothers. After working with them, we saw that our decision was the right one. They performed all the work very well and in the time frames they had estimated and stayed available for any questions we had after the job was completed. We are very happy with the results and happy that we hired them."

Subcontractors questions, answered by experts

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.

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.

Maintain open communication and address issues as they arise, ensuring contract terms cover potential delays.

The requirement for building permits varies by location, but most building departments will require permits for any changes to the structural components of a home. They’ll also require them for changes to the plumbing, electrical, and HVAC components, as well as any permanent improvements to the land, including concrete patios or foundations for additions or outbuildings. You also might need permits for things like roof replacement and window replacement, depending on your local government.

A construction lien results from unpaid services. For instance, if a homeowner hires a contractor to do a large renovation on their home and then fails to pay for the services and materials, the contractor can take out a lien on the property. This lien is a legal claim against the property for the amount of money owed. If the homeowner does not pay their debt, the lien may stay on the title until the homeowner tries to sell and cannot do so until the title is cleared.
