"We had new cement/stone front steps installed and needed wrought iron railings to complete the work. Benny responded immediately to my request and came the same day for an estimate. Once hired he again came immediately to determine final details to purchase materials. Actual installation took less than 2 hours and was done very professionally. I highly recommend Duro Welding for any metal railing project."

"The carpenter that did the job (Adam) was amazing. He had to expand the space for one window, narrow the space for another, and repair much cedar siding that had rotted away due to water damage. He also reshaped my patio door so it would close and lock more easily. He is a very talented carpenter and I have no qualms about highly recommending him."

"Vincent did an absolutely beautiful job on my cement and asphalt driveway. Their craftsmanship was top-notch. They finished the job quickly, and left the work area clean when they were not there. They stayed in touch throughout the process, and they take tremendous pride in their work. I have worked with hundreds of contractors over the years and these folks are among the very best and most reliable. Cannot say enough good things, also the prices were competitive, and they delivered a better quality of work than I would expect for a similar price."

Welding FAQs, answered by experts

Your typical household tools will not cut a metal pipe. To cut a metal pipe, you’d need more specialized tools like a pipe cutter or circular saw. Do not attempt to use these tools without taking proper safety precautions and wearing safety gear. It’s usually safer to let a pro cut a metal pipe, especially if you’re not confident in your skills with a heavy-duty saw.

Yes, you can cut plexiglass by hand using a sharp knife or blade (utility knife, box cutter, glass cutter, etc.).

Since water heaters are primarily made of metal, they’re commonly accepted by scrap yards and collectors. Don’t expect to fetch a high price, though—water heaters are mostly steel and aluminum, which aren’t high-value metals. Some components are made of more valuable metals, like brass and copper, but they’re a small portion of the heater and won’t affect the price much.

The best thing to cut metal pipe is a durable pipe cutter that is made for metal. You may want to measure the diameter of the pipes before purchasing a pipe cutter to ensure it will be able to cut your metal pipes. Opt for a heavy-duty option to cut through metal like steel or cast iron.

Yes, you can use a saw to cut metal pipes. The best saw to use is a reciprocating saw, but even a fine-tooth hacksaw can get the job done. No matter which saw you use to cut metal pipes, wear protective gear, like work gloves, safety goggles, and ear plugs. Apply a firm, steady pressure to the tool, and always ensure the pipes are secured so they don't move while you make the cuts.
