"We had cracks in the dyed mortar of the bricks above our garage. Grady took the time to match the color, even with the color having aged 10 years, and you would not even be able to tell that there was new mortar. If your project is anything like ours, you will not be disappointed."

"Attending young man nice. I was told I couldn't pay using a secured site like PayPal and offered my credit card over the phone. Was charged $7.50 more than the invoice total. Not that this is a big deal, but transparency and upfront honesty is huge to me... and I really don't like giving my credit card number to someone I don't know and have not met over the phone (which I had to do. Apparently, the additional $7.50 was the charge for doing this, which would've been nice to know ahead of time). I was also told I'd receive a formal estimate to repair what was found the morning of and have still yet to receive this. Days later and after having sent a few reminders/ inquiries about this. I hired this company based on the reviews I'd read; however, I'm disheartened to say, a 4 or 5 star rating was simply not reflective of my experience and interactions."

Welding FAQs, answered by experts

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. 

Some welding projects, such as repairing pipes or fences, require travel, whereas others, like furniture repair, do not necessarily require the welder to come to you. Travel and overhead factor into the overall cost of your welding project. Some of the most common welding projects include:

  • Metal furniture repair: $35–$100

  • Pipe repair: $200–$1,000

  • Small gates: $550–$750

  • Fencing: $1,200–$1,800

  • Fabricated sheet metal welding: $750–$2,500

Professional metal fabricators typically charge around $70 per hour, but the total cost of your project will depend on several factors. The largest cost drivers are the size, complexity, and design of the project, as well as the price and type of metal used. A good way to estimate the total cost is to multiply the cost of raw materials by four; typically, one-quarter of the total goes toward materials and three-quarters toward labor. Your geographic location can also influence costs, as labor and material prices vary by region.

It will likely take an experienced pro less than an hour to install a ground rod, which is another reason why letting them handle the job is such a good idea. Safety concerns aside, it would likely take you much longer to install a ground rod if you decided to take this one as a DIY job.

Cutting round ductwork requires precision and the right tools. A duct cutter, specifically designed for circular ducts, is ideal. First, mark the cutting line on the duct using a measuring tape and pencil. Then, position the duct cutter's blade on the marked line. Apply steady pressure, rotating the cutter around the duct. The sharp blade creates a clean, precise cut. Alternatively, a reciprocating saw with a metal-cutting blade can be used for larger round ducts. Ensure the duct is securely held in place while making the cut to prevent slips and maintain accuracy.
