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."

Garrie Pest Control is a Full service pest control company which has been providing state-of-the-art pest control to the Tri-State area for over 40 years. We are one of a select group of companies authorized to provide the Sentricon* System which totally eliminates termite colonies using ounces of low toxicity pesticide.

"They are very nasty / rude and not professional on the phone. When we call, it takes almost a week for them to show up. We recently called and scheduled for a date and when they Didn’t show up we called them again and they said no one called to schedule anything and we’re very rude about it. I’ve been a client with them for just over 3 years. The first year was amazing service but the last 2 years is making me look into other options."

LDR Group is the wholly owned subsidiary of the corporate parent Miscellaneous Enterprises Etcetera LLC, as originally formed in 1993 as a Delaware corporation, and later formed in New York in 2008 in the depths of the Great Recession. Originally doing business as Local Dad Repairs, it had at it's heart the goal of helping people in our community keep their homes repaired in hard times. In 2016, with the economy booming and the need for our services diminished,the company shifted it's focus to commercial consulting, serving millwork (custom woodwork and cabinet) companies in the NYC and Washington DC markets. When the corona virus pandemic besieged us all, we realized that there was an opportunity to once again serve our community, but in a more future focused manner that made full use of the skills gained in energy efficiency and home improvement we had developed over the years. LDR is now focused on providing a very special, very important need to our community and our world-hyper energy efficient Passive House buildings as new homes and home renovations. We will no longer do smaller remodeling projects like kitchens, baths, additions and basements. We have moved on to doing just whole house Passive House 'Renphits' or new build Passive House homes. Ask us how we can reduce the energy your home uses by up to 90%!

"Jeff and his team are very thorough, communicative, skilled, extremely knowledgeable and committed to excellence. He guided us from design and engineering and applications, researching materials and finding subcontractors ,through construction. He solved problems as they arose. He kept work moving despite covid, snowstorms and holidays! Recommend highly!"

"I hired Larry based on his reviews on Angies list. Larry was prompt and arrived on time. Larry talks a lot and missed on some crucial things like coding violations and blatantly wrong things that should have been caught by an experienced inspector. Here are the top things he missed which I had to painfully learn during the the last 2 years since I owned the home... - Poor shape of the roof. I noticed this during inspection and asked him about it to which he said they looked fine. But they were not fine and pieces of it has been blowing over during storms. - Gas connection in kitchen violates code. The inspection report he sent was a useless template and after inspection I was getting sales calls from home warranty services and other useless stuff."

Insulation questions, answered by experts

The type of insulation you need in your home depends on your location, the installation site, and your region’s climate. According to Energy Star, insulation in homes in the Southern United States should have an R-value of between R30 and R60 in attics and R13 to R25 in the floors and walls; homes in moderate climates require R values of R38 to R60 in attics and R25 to R30 in floors and walls; and homes in northern states require an R value of R49 to R60 in attics and R25 to R30 in floors and walls.

As long as your existing insulation isn’t compromised, you can add new insulation directly over them. Inspect your insulation thoroughly and make any minor repairs. Then, add new insulation on top of it. You must be completely certain that there is no contamination or mold growth before doing so. That said, when unsure, consider removing old insulation and lay down fresh ones.

Fiberglass is considered a favorite garage insulation choice due to its combination of affordability, ease of installation, and overall effectiveness. Fiberglass provides good thermal resistance, helping regulate garage temperatures and minimize heat transfer. Additionally, fiberglass is moisture-resistant, reducing the risk of mold or mildew formation.

Yes, you need a 1.5-inch to 2-inch air gap in a cathedral ceiling to allow proper air flow and prevent cathedral ceiling venting problems. This amount of airspace allows warm, moist air to properly leave your ceiling to avoid moisture build-up and other issues that put your home at risk. You can also add an air vent for extra air flow.

Winterization includes blowing out water, shutting off the system, and insulating exposed components to prevent freezing.
