"Excellent! I could not have asked for a better crew. JT, Shaun, Pedro and Kayla were my direct contacts and all were very professional. Western Pacific Roofing came to the rescue just before this last big rain. They were not prepared to repair my roof upon first observation, however, they were able to secure the exposed area so as not to allow further damage from the impending rain storms. We survived the rain, they returned the next business day after the rains. Roof is repaired and I’m completely satisfied with my overall experience. Western Pacific Roofing has become my go to company for all of my properties’ roofing needs..."

Welding questions, 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. 

You should not do your own welding unless you have the proper training and experience. Most home electrical systems can only handle MIG welding, which creates weaker bonds than TIG welding and won’t work on certain metals or metal thicknesses. Both welding forms usually require the use of shielding gas, which can be dangerous to store at home. Additionally, welding machines create temperatures of over 3,000 degrees, and the sparks can blind you if you don’t have the proper equipment. As such, it’s usually better to hire a professional welder for your welding projects.

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.

This all depends on the tools you have on hand and whether you’re trying to cut a straight line or shapes. 

The best tool to use for straight lines is either a circular saw or table saw. When cutting shapes, a jigsaw will be the easiest and most precise tool to use. 

Yes, you can cut up a box spring., but you’ll need to do so in layers. You can clear the fabric and fluff away to reveal the springs before removing them as well.
