"I bought the Big Deal which was just for a single top coat to reseal the deck surface.  However, my deck was in a little bit worse shape than the deal allowed.  However, Ryan was awesome and added in sanding and then did the reseal for no additional charge.  The surface is not perfect but that is due to the rough pre-condition it was in and not his fault.  Shortly after the reseal the deck drains started leaking in to the garage below.  Ryan and crew came out again to fix the drain at no additional cost.  Again, this was not in the deal I bought but they provide such great customer service.  I would definitely use them again and will recommend them to friends and neighbors!

"Tony and his crew arrived on schedule, worked hard and did a great job on a complicated roof. The workers were pleasant as well as skilled. Very satisfied with both price and result. Would use again for other construction services they provide. Roof will outlast me."

"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..."

"The whole process was very smooth. They came out and spent a couple of hours assessing the problems...turns out we had several. The water heater burner had failed and was under warranty. But they also discovered our pressure regulator had failed, our gate valve was frozen, and we had a pipe leaking in the wall! They found the necessary part for the warranty repair and drove 50 miles each way to get it rather than make us wait 1-2 days for for the part to be shipped. They stayed until all the problems were resolved which was greatly appreciated! (My wife and three daughters were not relishing cold showers!)"

"When they came to the house, they were very honest.  I had a plumbing problem that they could’ve easily told me you need to do it now, but they really worked with me and kind of advised me on what I need to do long-term if I couldn’t do the work now and it worked and helped me save a bundle of money.  The quality of the work have always been great."

I am a single woman and we all know that many contractors like to take advantage of the lack of knowledge one might have in this area.   I interviewed many contractors for my project and found most to be substandard (to say the least) to my needs.  I found Bernal Construction from the time I first contact them to be very professional. Their Project Manager, Louise Williams is on top of her game from beginning to end.   It was a delight to work with her on this project.  She made sure that every thing was on track with this project which was delightful, since I was not in town for most of this remodel.  I knew I could depend on her. The owner, Raul Bernal is not only a great craftsman but insists that every detail of the project be up to his standards, which are high.  Both Raul and Louise are detail oriented and insisted that the job was perfect before giving their final blessing and handing me my final bill.  And even though the final payment was made, every time I call with a minor issue, they have been right here to correct.  I have felt very safe and secure not only with them but with their whole team of craftsmen. Thanks for inviting me into your family and for all the hard work!  GOOD JOB ALL, and I love the end result.

Basement Waterproofing questions, answered by experts

Costs depend on the area's size and condition, damage extent, and chosen method. A professional evaluation provides a tailored estimate based on specific needs.

Proper basement ventilation is very effective at reducing humidity. Without enough ventilation, your basement is prone to mold and moisture damage. Your basement should have as much natural ventilation via windows and doors as possible, and if your budget allows, you should also consider installing an ERV system to keep basement humidity levels at bay.

If you don’t wish to dig it out and convert it into a finished basement, you can still encapsulate your crawl space to protect it from damage for an average cost of $5,500. Finishing a crawl space beyond this isn’t really worthwhile, as the low ceilings mean you won’t be able to use the area as living space.

As the first layer of water protection for your roof deck and the building materials below, underlayment is designed to prevent water damage, so it’s okay if it gets wet. However, you shouldn’t rely solely on underlayment for protection. If rain interrupts your roof project and you have all of the underlayment down, you’ll likely be fine, but you should install shingles over that layer as soon as possible, as long-term exposure can lead to water damage.

Water can seep into porous materials like wood beams, floor joists, and roof rafters within minutes, but they’ll need to see prolonged exposure before you have structural damage. Mold can start growing within 24 hours, and mold can eat away at the structural components over time. Wood rot is more of a concern, though. Wet and dry rot are fungal infections that set in in moist conditions and rapidly deteriorate wood, causing major structural damage within just a few months in some cases.
