We noticed some mold in our family home and knew it needed attention. I called a few businesses and Global Prevention Services was the first to respond. They expertly assessed the situation and gave me a quote later that day. Not only was their quote extremely comprehensive, it was the best value.
The service people were timely, courteous and respectful. They cleaned up after the job very well.
I can honestly say I would give this company more than 5 stars if that were an option.
As a Real Estate Broker, I will most definitely be referring this company to my clients.

Fantastic experience working with Micheal and the GPS team remodeling my back patio ceiling with stained wood planks. Quote was received shortly after my request and they provided valuable input on the project. The GPS team always followed up on my questions. Once hired, they did an excellent job installing the new wood ceiling on time and in a professional manner. This big project took one week to complete and they always showed up on time and cleaned up after each day of work. One of the best experiences if not the best experience I have had working with a contractor. I would highly recommend working with Micheal and his team. Thank you GPS!

Jeff presented GPS with a terrific and challenging project concept and we are most proud of the final result. We have included one photo of his amazing patio in our Thumbtack profile - the final finish is very striking, thank you for letting us perform this important work.

Kim the Project coordinator was responsive and polite. Rudy and team were AWESOME!! Probably THE BEST construction/project team we have ever worked with!! We have a couple of other upgrade projects on the list...this is the group and company I want working on them. We were not disappointed and in fact are ecstatic about our finished project! I would recommend GPS to anyone.

Devin,
Thank you for your great review, I really appreciate your taking the time to recognize the team of people who are the most valuable asset of GPS. Projects like yours bring us great pleasure and pride, as the end results are so rewarding and positive.
We perform a great volume of damage repair and remediation work. These are important projects that bring properties back to like-new condition and get the occupants back to their normal lives. But, additions and improvement projects, like yours, allow us to add value for the owners and fully utilize our variety of skills.
We are here for you for any need, new or old - thank you for your trust in GPS and allowing us to become your contractor resource.
Best regards,
Michael Himelfarb

Had a wonderful experience with GPS for my partial guest BR remodel (demo cabinets,counter,sinks, new tile floor, drywall repair/paint, new vanity install with sink hardware and mirrors). Very professional, pleasant workers who were timely, worked very hard, and finished the project in a day. Paid much attention to detail and consulted me for details in question (i.e. baseboard design, exact mirror location, etc..). I will definitely use them again for the remainder of the BR remodel-tub/shower and tile remodel. One of the best finds on Thumbtack. Thank you GPS.

We have hired GPS for 2 major projects! They removed load bearing walls and installed a beam to open up our living room and remodeled our kitchen! Great quality work, excellent customer service, and reasonable pricing! We will continue to use them for our major projects. (First photo is in an unfinished state because we only hired them to handle the walls. We did the rest ourselves.)

FAQs
What should the customer know about your pricing (e.g., discounts, fees)?
Our service does require an on-site visit (provided at no charge in our market areas) so that all the details can be collected to properly service the needs of our clients. No matter if the project is brand new construction, a minor or major remodel or a remediation or emergency situation, true and accurate pricing requires data collection, site awareness and the determinations for equipment, materials, labor and product needs. Those who will quote site unseen will have to change their quote (later on) or have built-in price protection that will only serve themselves.
What is your typical process for working with a new customer?
GPS is different and much of what we do that separates us from our competitors are trade secrets - literally. But, we can offer in answer to this question that most of our success lies in 'listening'. We are all about the client, their desires and needs or for those looking for direction or advice, we enjoy that too. It is such a simple concept, but so few businesses ever master the art of satisfying their clients - completely, each and every time. We meet with our clients and prospects, follow their lead, and augment their projects when asked to do so. We then communicate continuously until we have delivered on their vision. No lip service, no excuses, just a focused effort to generate results, create associations and enjoy the work and the relationships.
What education and/or training do you have that relates to your work?
We are constantly gaining knowledge, attending seminars & events and our key people are required to maintain their certifications through continuing education. The Founder of the company speaks regularly to audiences within the industry and to real estate professionals, builders and others related to the development, construction and maintenance of real property.
