"Since having used GMG and Oscar I would never ever use anyone else,   he will work with you until you are 100% happy, best customer service I have ever had from a contractor and the work is excellent.  His guys are clean, polite, and very professional. He has done a couple of projects for me including bathrooms and a complete 2000 square foot plus basement and now I am saving my pennies to do my kitchen.  His price range is very competitive; however his satisfaction oriented service beats any lower bid you might get...Yes I would highly recommend his service." Michael M.


"We're really happy with how our renovated house looks and functions. Thanks for all your hard work." Ethan B.


"I am most happy to endorse Oscar Molina and GMG Services.  Oscar has done three major renovations, two complete bathrooms and guest room, for me, cost was spot on, and the quality of work unsurpassed by any contractor I have ever used in past.  I have recommended him to several others all of whom accepted the contract and all well pleased with his work. And I will only use Oscar and GMG Services for any home improvements, repairs, fixes needed.Oscar sizes up the job, makes recommendations to improve the effort as well as to contain cost.His works were always well supervised, always on time, the work was exceptional.  Each day any demolition and/or other debris cleared up and out as if they had not been there other than the work progress.  He and his team are totally honest and trustworthy a trait I prize.  I give them the keys, go about my business while they work.  Never any issues" Charles G.


"We just came from the house where Alex and Jaime were working hard on various things ... we appreciate you sending them out to work on Saturday ... by the way, if we haven't said this before, all of your guys do a great job, especially Alex ... we don't think there's anything he can't do!”  Roxanne S.


“Your guys did a great job, as usual. We like to remind you every once in a while how much we enjoy the work you've done for us.”  Greg & Sarah C.​


"We want to thank you, Bob, Sofia and all for all of your work on this project. It was wonderful to deal with you and we particularly appreciate the fact that you were prompt about returning calls. Your stone work was especially good...Your guys were punctual, courteous, and professional...kept the inevitable dust and dirt to a reasonable level. We are very pleased with the way the project turned and we hope to work with you again...As you know, we have already recommended you to several friends and will continue to do so." Hill W. & Michelle B.


“A neighbor…sent me an email saying: ‘Your garage looks fabulous! Terrific job by your contractor!’ Thanks to you and your crew.”  David S.


“I cannot say enough positive about GMG Services.  From the very first contact when an estimate was being given, they were responsive, punctual, clean-cut, and professional.  Their estimate was extremely fair and they were completely transparent about what they were charging for, with no complicated ‘allowances’ some contractors offer, which can make it difficult to compare quotes and can mask the true cost of their service vs. the materials cost.  When drawing up the contract, I needed to get a variance from my community for the work, and I asked if we could void the contract if that didn't come through for some reason - Oscar from GMG (more below) offered to put a specific clause in the contract without me even asking.Before contract signing and during the work, GMG was incredibly responsive.  Every email was answered in a matter of an hour in most cases, as well as every phone call.  My main contacts, Oscar and Aldo, and their field crews and supervisor operate on cell phones and Blackberries, which allows them to offer this level of service.  On the rare occasion I had a question or concern, GMG was prompt and professional in addressing it, and they were never ignored.  One time, the crew inadvertently left a garbage bag from the day's work in the backyard, and Oscar called on a Friday night to make sure it was OK if they picked it up the next day, and offered to have them come out that night.  While this was hardly necessary, it demonstrates the level of professionalism and customer care you can expect. The work crews showed up punctually every day, worked a solid day all days of the week, and were friendly and professional.  They, and GMG overall, took excellent care of the house - they put down cloths and protective paper and plastic to protect the surrounding areas from harm, and cleaned them up at the end of the day when appropriate.  They kept a clean work area both during and after work hours. The quality of the work and final product are wonderful.  The work is detail oriented, uses high quality components, and does not cut corners.  It was done exactly as specified in the contract, which was also very detailed as to what they would do and the quality of the work practices.  Anytime I asked if they could make a slight adjustment, or position something differently, they always did their best to accommodate us.  Their materials, work practices, and attention to detail is first rate.Two people in particular deserve mention.  Aldo was the supervisor who was present at the site at least two days a week to monitor the quality of the project and make sure we, the customers, were happy.  We had his direct cell phone number and he was always responsive in returning calls.  Oscar was the person who gave the original estimate and was my other main contact.  He, and Aldo, were both superior in returning calls and emails, and in being responsive to customer needs.  They clearly know the business from both the construction end and customer service end.  I travel during the week for work and my wife works as well, so the last thing we needed were people who didn't respond and who needed to be constantly monitored - this was never the case with GMG.  Those who have dealt with unprofessional people in any field know how valuable this can be, and even more so when having them in your home. GMG's method of contracting is find extremely fair.  The contract with them is for the labor, and one selects and pays for the materials themselves.  After that, GMG takes over to make sure the quantities and dimensions are correct.  They have several excellent suppliers (which you're not required to use) that they work with and who help with design, and pass on the full contractor's discount, which can be considerable.  GMG's payment structure is also very reasonable - the initial deposit was 25%, well below the one-third many firms ask for, and the remaining payments are spread evenly over the project. GMG provided some of the best customer service and quality work I have ever received, and they will without question be on the top of my list for my next home project.  I recommend them unequivocally”.

"GMG Services remodeled two bathrooms and a bar area in our home in Arlington, VA. GMG was one of three contractors we got quotes from, and we liked their punctuality, prices, and their ideas about how to best use the space available for the two bathrooms we wanted to re-do.Once we signed the contract, the work went exactly as planned. We were sent to wonderful providers for countertops, sinks, toilets, showers and tiles– everyone we worked with was fabulous, and it was clear they all had a great relationship with GMG. We were referred to GMG by a good friend, and we are very pleased with the way the work turned out. Beautiful job, on time and within budget." Holly H.

​"Our kitchen is beautiful! First I want to thank everyone who worked so hard and so well on our home renovation project. I also want to commend you for outstanding service. In a few short weeks you gutted our 40-year old worn out kitchen and transformed it into a show place. Every detail has been handled with great attention and skill. All of the craftsmen performed excellent work and were so friendly too. The carpenters, tile layers, the painters and walls fixers, electricians, and plumbers, each one is an expert...Again, I thank all of you at GMG for creating that little masterpiece of a kitchen...I am still marveling at the beautiful and sold tile work...I will highly recommend your service and would happily show my home to anyone who is considering a renovation project with GMG."

“We are writing to express our sincere appreciation and gratitude to you and your crew for the excellent work in remodeling our two bathrooms.

​“GMG did a great job in accommodating us.”  Margot H.​


​"My wife and I were more than pleased with the entire process. There was never a hint of pressure from Oscar to speed up our selections. He (they) understood that we were amateurs   and wanted to be really certain before committing to placing an order. Oscar worked closely with us on the kitchen design. He has a real talent for understanding the client's s objective  and the best way to get there. He was  patient with changes and suggestions we thought of after the basic design was agreed upon. His clever use of space transformed our kitchen from pretty large and ho-hum to a place that everyone seems to be glued to. The GMG installation crew was prompt, efficient and pleasant. They cleaned up every day, and stayed until the task was completed. They were professional in every aspect. I think you get the impression that we are really pleased with the efforts of GMG. They have earned our highest respect and our unqualified recommendation."  Robert & Lynn C.​


“This really was an outstanding job.”  Mike H.


"Heidi and I would like to thank Oscar, Aldo, Sofia and of course, Marco and all the talented workers who did such a beautiful job on our new kitchen.

​"Thank you for all of the work you did on our kitchen remodeling project and the various other projects around our home during this past summer!! From the design ideas you created to the many choices and options you provided, you were extremely knowledgeable, professional, and friendly...We can't say enough about your GMG work crews also. They were all extremely proficient with their respective disciplines. They were hard working, trustworthy, and always willing to make every effort to make the finished product perfect... We certainly hope to work with you on another project in the future."  Robert C.


"We are extremely pleased with the outcome and our experience working with your staff. All of the workers were very pleasant and accommodating. Aldo is a very competent man and a joy to work with. Marco takes great pride in his work and wants to make the customer happy...We will definitely call on you in the future for our home and garden projects." Candy S.

"I've been using GMG exclusively for the last 15 years for 4 different projects. Other than my bathroom, they have totally renovated my entire condo including a recent complete renovation of my downstairs bathroom.  I have absolutely no reservations using them again and am chomping at the bit to have them renovate my bathroom next year.  They do outstanding work, always finishing on budget and just as importantly, on time.  Oscar is great to work with.  I can honestly say, when comparing experiences with my friends on contractors, I've never been able to offer any of the horror stories they always have." Steve G.


"This note is to thank you again for the lovely bathroom GMG installed... I would like to know that I'm continuing to receive so many compliments from guests. During the installation, I was very impressed with every single member of your work crews, especially your field liaison--I think his name was Aldo.  All of the workers were skilled, knowledgeable, and very neat!" Jane L.

“We are very pleased with our new kitchen! It reflects your quality work as well as your capability to make the whole process go smoothly. We really appreciate your finishing the job so quickly. From Oscar's original drawings to the final product, Aldo moved this project along as fast as possible without sacrificing any quality. He provided advice, pointed out aspects I had overlooked and always, always returned my phone calls. A special thanks to him. All of your employees were responsible and careful and did fine work. Every effort was made to keep the demolition dust to a minimum and to clean up at the end of each day. The tile was laid perfectly, the cabinets were installed so straight that the granite installers were impressed, the lighting works beautifully and reaches all the previously dark corners, and the dry wall and painting is really first class.”  Anne P.​


"Thank you all....for your fine work." Christine A.​


“Oscar Molina and GMG Services have done several major renovations for me---the most extensive is a complete renovation of both bathrooms, a bedroom, as well as other "handy man" repair jobs.  All included extensive electrical, plumbing, carpentry, and painting GMG employees were always prompt, efficient in their work, respectful of the furnishings and home, always clean up daily, and totally trustworthy to work in my home without me being there, a trait which I value highly and one not often found in other contractors.  All work completed to my complete satisfaction… GMG pricing is always competitive and the quality of the work more than justifies the cost. Mr. Molina is a sharp, professional, ethical, businessman, always polite, always spot on in his details of the work, the pricing, etc.  I enjoy working with him and GMG.  I highly recommend Oscar and his people without reservation.  I have recommended him  to numerous others and all have been more than satisfied with his work.” Charles G.

(our) kitchen is truly wonderful.Thank you so much." Bryan & Cynthia P.

Thank you again for all of your hard work." John M.
