"I recently hired Arnie - Fences Plus contractor to add wooden stairs and a gate to my balcony, and I couldn't be happier with the result. His craftsmanship is top-notch, and he communicated clearly and politely throughout the process. He was always on time and his estimate was very reasonable compared to other contractors I considered. I highly recommend his services!"

"Dana was the foreman on a major remodeling project on our property. We added a guest cottage which involved excavating over 100 ft.³ of hillside, foundation, as well as construction. He also remodeled the main house extensively from a concrete pour to new roof, electrical flooring, fine carpentry and everything in between. Throughout the 2- year project, Dana was attentive to detail, honest, mindful of the budget and schedule, and collaborative on creating solutions. He is such a kind hearted person, and was a pleasure to have around the home. I canâ t say enough good things about String Theory Construction!"

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, but you’ll need reliable steel-cutting tools and safety gear to get started. Shipping containers are typically around ¾ inch thick, so it’s entirely possible to cut through them, but experience and the right equipment are very important. When possible, try to get a container as close to the size you want it as possible.

The average cost for a welding project is about $300, with typical costs ranging from $125 to $490. However, prices can be as low as $125 for very small jobs or exceed $1,200 for large or complex projects. Welders typically charge an hourly rate between $65 and $150, depending on their experience, and many charge a minimum fee to cover overhead and travel expenses. The total cost is influenced by several factors, including labor, the cost of materials like metal rods and shielding gas, the type of metal being welded, the project's size and complexity, and your geographic location. For a precise quote, it's best to ask a local welder for an estimate based on your specific project.

To maintain custom or fabricated metal structures and extend their lifespan and appearance, perform regular cleaning, apply rust prevention treatments, and use protective coatings.

Cutting rectangular ductwork requires careful measurements and the right technique. Use a measuring tape and pencil to mark the cutting lines accurately. Tin snips are excellent for straight cuts on smaller ducts. For more extensive or thicker rectangular ducts, a reciprocating saw with a metal-cutting blade is effective. 

Ensure the duct is well-supported and secure while cutting to prevent wobbling and maintain precision. After cutting, use a metal file to smooth any sharp edges, ensuring safety during installation.
