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."

Licensed Florida contractor specializing in exterior renovations and repairs including siding, soffit and fascia, windows and structural repairs. We provide a 5 year warranty on most major renovations and a long list of references from happy customers. Call us for a free at home consultation and detailed written bid for your renovation project. We are a Preferred remodeler with James Hardie Siding.

"We used John Anderson to install our new James Hardie house siding and his company did an amazing job! We ultimately decided to use John for his experience and his trustworthiness. His subcontractors were professional and friendly and did excellent work. Heidi in his office was super helpful and informative from start to finish and the process was smooth and seamless. They answered all my questions fully and promptly. I found John and his company to be straightforward, knowledgeable and reliable, which are characteristics I value highly when trusting someone with such a big project for my home. He even came out and replaced a bad piece of trim right away after we noticed some issues with it after the house was painted. It had been installed correctly but was just a faulty piece, which seems rare but either way was fixed quickly and we are happy. We know we made the right choice for our home project by going with John Anderson and are so pleased with the result. Thanks John and Heidi!"

David Spence Inc. takes pride in giving the meticulous attention to detail a customer deserves. We are an appropriately licensed, bonded, and insured company. All projects are done with a contract.

"David Spence did it again!! We had 2 bathrooms that needed to be gutted and one a conversion from tub to shower only. Not only did David Spence come in at a fair price, everything was done professionally and in a timely manner. Tile for second bath was running behind so instead of having us wait for it to come in, he gave us a choice to go pick out tile from Floor and Decor, which we did and the bathroom looks beautiful. Great customer service! We love that Ched and Tristan took time to answer any concerns we had along the way and they kept us up to date on the daily work. Both of our bathrooms are totally unrecognizable from where we started. You can’t go wrong hiring DAVID SPENCE INC. for your remodeling needs. We would definitely recommend him and his team."

"It started with their horrible AI voicemail system. Then waiting for their representative showing up two hours past the visit window. The quote for work was $1760 to animal proof three dormer soffits. The work effort for the two technicians took less then 3 hours and the results was a complete eye sore for all to see. The technician screwed flimsy sheet metal to the fascia boards and glued it to the shingles. Everything was uneven and rushed. At a rate of $300 an hour per technician, I would expect the work to be neat and precise. I text and called to express my concerns and when the manager finally came out he said that this is what they typically do and can not fix it. He offered to refund my deposit but failed to mention that they are retaining 25% of the total cost. $440 dollar spend for holes in my fascia boards and glue on my shingles. Do not do business with this company."

Insulation questions, answered by experts

The best R-value for home insulation depends on where you live and where you’re installing the insulation. Your climate zone plays the biggest role in determining the correct R-value, so be sure to know which zone you live in when determining the R-value you need.

Interior walls don't require insulation. However, there are a couple of reasons you may consider adding it in some situations. Insulation in interior walls is excellent for sound-dampening between rooms and can help maintain a regulated temperature in insulated rooms by lowering the heat transfer between adjacent areas of the home.

The most insulative type of insulation for behind drywall is spray foam insulation, but this is the most expensive insulation available. The most common insulation—sometimes considered the best for the value you get for the money—is fiberglass roll or fiberglass batt insulation, which is significantly more affordable but also far less insulative. The best kind of insulation for your house will also vary based on the climate in your area, your budget, and more. A professional insulation company can help you decide which type is best for your home.

Roof vents help cool a house because as they allow hot air to escape, the temperature regulates inside the attic. If vents are defective or there are not as many as there should be, the attic becomes hot and stuffy. Without roof vents, air conditioning has to work harder to maintain a consistent temperature in the attic.

R-value stands for resistance value and is a number assigned to insulation that states how good the insulation is at heat transference (insulation). The R-value of injection foam is around 4 which homeowners will be happy to know is actually quite good. Another benefit of injection foam versus fiberglass foam is that the colder it gets, the more injection foam retains its resistance properties, whereas fiberglass tends to lose its efficiency in colder temperatures.
