THOROUGHSPECT, LLC
THOROUGHSPECT, LLC
Your home will be inspected & documented w/annotated phots provided to show what has made it in and how including but not limited to water in your basement, mice, bats, flying squirrels. In addition, This will help you understand what needs to be done to stop them from getting inside in the first place and then we can professionally seal it with non-chewable materials. We service lower Fairfield County, CT and parts of Westchester County, NY. Brian’s career in the pest control business began over 25 years ago. He spent three years in the southern United States learning from a world-renowned entomologist (among others) and helped start the Sentricon baiting program for termites with Dow Elanco. Brian advanced through the field to eventually run a major sales force and acquired a distinctive edge in the business. Through this experience, Brian realized he wanted to return to his home state of NY and create his own niche in the rodent control market. He developed a highly successful approach, rejecting the easy but environmentally unsound approach of poison – and instead relying on hard work, common sense, and the correct materials to prevent rodents from entering people’s homes in the first place. Fast forward a few years, and Brian began to realize there were additional niches in this area that needed to be more friendly towards the environment and the clients’ health. He therefore co-invented the Enviroboot® Dust Suppression System to help control the toxic silica dust that is produced when concrete is broken with a jackhammer. The result was a reduction in toxic dust greater than 97% according to the EPA and was awarded the 2006 US EPA CLEAN AIR EXCELLENCE AWARD. Brian M. Sweig has a special set of skills and licenses in NY and CT including Nuisance/Wildlife, Home Improvement, and Home Inspection (CT), Mold Assessment and looks forward to helping make your home a better place for you and your family.
"Brian and his team are wonderful. I give them an A+ rating for the service they provided in both my home and my parents. Brian is professional tohis core, honest and fair with his cost. He explains everything that needs to be done and does a great job fixing the problems."

Guardian Protection
Guardian Protection
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."

FAQs for insulation service projects in Norwalk, CT
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
