Protecting homes and businesses since 1950, Guardian Protection is one of the nation's largest and most highly regarded security companies. We provide smart technology, 24/7 professional monitoring, and peace of mind to hundreds of thousands of customers. Our products are installed by experts, monitored by real people, and truly make a difference. We do what we do because of one simple truth: life is better when it's safe.

"We hired Guardian to install our security system at our Washington, DC, business. The service and quality of the work was horrible. We had cameras and an alarm system installed; it was a relatively large system. They outsource most of the work to various vendors. They could not manage their vendors; what was supposed to take a week took two months. The sales rep did not return calls, and you could never get anyone in management on the phone. Random people would show up at unannounced times. The few things that an actual Guardian employee did were they made a huge mess of our newly remodeled office and were rude to our staff. We have offices in five markets across the US and have high security at each; we have never had such a poor experience."

Pacific Coast Termite has a great history serving California since 2007 by co-owners Dennis Wilson and James Grande. Both men agree that a large part of their company’s growth is attributed to word of mouth and referrals along with great reviews and A+ rating with the Better Business Bureau have also helped. Today the company has full in-house wood working divisions, offers comprehensive termite control, rodent control, and attic services such as attic cleaning and TAP pest control insulation to replace old soiled attic insulation.

"Horrible experience, the employees were very poorly trained. They severely underestimated the time to do the job. They sealed holes in vent screens with big globs of unsightly goo. The crawlspace access door wouldn't stay closed do they pried a stepping stone out of the garden and used that to hold it closed. They spit sunflower seed shells all over, including on our front porch furniture. They vacuumed the old insulation out of the attic but there was a leak in their system and it spewed old insulation and rat droppings all over the inside of our garage and on open storage shelves, and they didn't clean it up. They only apply blown-in insulation and our ducts are covered with sheet insulation, so they didn't remove that insulation or the rat droppings on the tops of the ducts. I could go on...."

Some areas were very difficult to reach, but they found a way to do the treatment anyway. Planet Orange is the company you can count on for taking care of your home that has termites. I will highly recommend it to all the people I know!"

Westshore Roofing, Inc, a family owed business was founded in 1992 by Paul Fowler. A Diamond Certified company, we strive for 100% customer satisfaction on all of our jobs. Are current staff comprises of 35 full time employees. We continuously educate our staff on the latest roofing trends and innovative products being introduced into the market place. This enables us to install many products are competitors are unable to offer, such as Standing Seam and Stone Coated Steel Roof Systems, Imitation Cedar shakes that replicate the look of real Cedar wood shake but are manufactured with the latest Polyurethane Technology. Are estimators are informative and able to educate on how to best construct an energy efficient, long lasting, performing roof system.

"We reached out to four roofing companies to quote our re-roofing project. We compared them on professionalism, quote thoroughness, feeling of trust and integrity with the salesperson, and knowledge. Westshore ranked highest hands down. They were not the cheapest, nor were they the highest bid, but they were the best. We felt so comfortable with Ben, and rather than try to upsell us as others did, he helped us figure out ways we could get the job done within our budget. The quote offered several options which was quite helpful in our choices. During our decision period, we had several questions and he responded immediately every time. When it came time for the work, the crew was always on time and professional. They cleaned up and you could barely tell they were even here at the end of the day. We were glad to see that the crew was able to take several water breaks (in nearly 100-degree heat) and time off for lunch and they still finished the job ahead of schedule. It showed us that Westshore takes care of their crews. We highly recommend Westshore Roofing."

FAQs for insulation service projects in Penngrove, CA

When choosing a professional insulation installer, consider asking these questions to determine the best fit.

  • Will you address air leaks in my house?

  • Can you provide an R-value (heat resistance) fact sheet?

  • What kind of insulation will work best for my home?

  • How do you handle signs of a water leak?

  • Are you licensed and insured?

  • Can you provide customer references?

The best type of insulation for your home depends on what you need, so the answer will depend on your specific situation. If you’re building a house, structural panels are easy to install during the building process in addition to being the most energy efficient type. If you live in a warm climate, reflective insulation may benefit you more as it costs less than other insulation types. And for standard attics, loose-fill, spray foam, or blown-in insulation work well.

If you plan to heat or cool your garage, you’ll need to insulate the garage ceiling. Insulating your garage ceiling will make your garage much more energy efficient and save on heating and cooling costs. Not only does insulation make your garage more energy efficient, it helps reduce noise and can extend the life of your garage roof. You can use fiberglass, cellulose, mineral wool, or spray foam insulation for this project.

In some cases, you may not have enough insulation to properly regulate your home’s temperature. Watch for a few signs your home needs more insulation, such as:

  • High heating and cooling bills

  • Uncomfortable room temperatures 

  • Ice dams on the edge of your roof 

  • Roof leaks

  • Cold floors and walls

  • Freezing pipes

  • Temperature fluctuations

  • Visibly low insulation

  • Noise problems

  • Pest problems

On average, insulating an attic costs about $2,500, ranging from $1,500 to $3,500, depending on the insulation type, amount, and your attic’s accessibility. Additional cost factors include sealing air leaks, removal or replacement of insulation, and inspections. Types of insulation include:

  • Blown-in: $1–$4 per square foot

  • Spray foam: $2–$5 per square foot

  • Batt: $2–$4 per square foot

  • Structural insulated panels: $4–$7 per square foot

  • Loose-fill: $2–$5 per square foot

  • Reflective: $0.50–$1.50 per square foot
