Giant Landscaping Services We were born and raised in Londonderry, New Hampshire, then established our landscaping company in Manchester. We know what it's like to be part of a community. The community has given our business phenomenal growth over the past several years, due largely in part to the confidence that local homeowners and businesses place in us to do the job right.

It's only natural that we want to give back. Funds are limited for everybody, and there's no shortage of needs out there. We have selected four non-profit organizations to donate time, materials, and funds when we're able to, because we really believe in the value these local organizations provide to our community.

Snow removal
Report
Winter storms in New Hampshire can be a hardship on everyone, but no one is more affected than local business owners. Finding the right commercial snow removal contractor is key to everyone's bottom line. If customers are inconvenienced because your parking lot has not been plowed you could lose customers.
Bark Blowing
Report
Spring is a crazy time of year for landscapers in New Hampshire. Everybody is sick and tired of winter and wants their property clean and buffed with a fresh covering of bright red mulch. The property management company that gets this done quickly is a hero to their clients. For both landscapers and property management firms, this rules out moving mulch with a wheelbarrow!
Construction
Report
We work with property management firms, commercial realtors, and private commercial property investors to prioritize landscape improvements so they can budget for them. A Property Condition Assessment (PCA) does not only apply to internal and structural parts of commercial property; exterior components and systems break down as well.
Maintenance
Report
As the neighborhood landscape company in Manchester, we would love to see urban renewal projects - especially businesses taking pride in their neighborhood. But we understand the budget. That's why at Giant Landscaping we offer tiered landscape maintenance programs for property management firms and commercial clients.

Won't travel 20 mins outside of Manchester where they are located. Refuse to take on a new customer because of it.

Giant landscaping is here today doing my spring clean up. They were on time and have been steady working for 5 hrs. The guys are professional curtious and are doing a finominal job. I have used several landscaping companies over the 37 years I have lived here and Giant Landscaping is the best I have ever had. I would highly recommended them especially if you are particular about your yard as I am.

If you're looking for a company that comes equipped with an integrated project management team that you can trust to delivery high-quality workmanship, look no further! I am customer that expects work to be done right and Giant Landscaping delivered high-quality results on both backyard projects we retained them for. We now have a completely renovated new living space that has provided a beautiful escape to relax with friends and family.

Thank you Giant Landscaping! We'd love to give credit to Kyle ("Gunther"), our project manager, who handled our design execution and crew management like a true pro. His cheerfulness and calm disposition during a few project challenges we encountered was like a breath of fresh air. We'd give ten stars if possible!

I recently had my entire lawn reconstructed by Giant and they did a tremendous job from Jeff estimating, Hayley scheduling, and Carl and the crew working the property - it was a smooth and pleasant experience! The lawn looks fantastic already and I'm very glad I chose this company to do the work. Services: Sod installation, Seeding

If your looking for Quality and Reliability at a fair and reasonable price. Giant Landscaping is the one for you. We wanted to put a new lawn and irrigation in and started calling around last year. From the first call to Giant Landscaping in talking with Charlene I knew I had the right company for the job. Charlene is extremely kind, Patient, and knowledgeable and just really wants you to have a great experience before, during and after the process.

I can't say enough positive things about this woman. She is a true professional! I also spoke with Hayley on occasion and like Charlene, kind, patient, and polite. Thank you Hayley. Eric was in charge of the irrigation and this guy is a genius at what he does. Very thorough, knowledgeable, & professional, and just takes pride in doing a great job for his customers. Eric definitely goes above and beyond to make sure thing are done right.

Thank you Eric! Even the owner Tim was onsite working on the landscaping to ensure things were done correctly and to our satisfaction. I can honestly tell you from beginning to end this company was "Top Notch " and "Spot On "! Thanks again to everyone @ Giant Landscaping! Your the Best!

Jeff and his crew were easy to work with Kyle his foreman and crew were exceptional. Alway had a answer for all my questions. They went above and beyond. Our home is on a hill the retaining walls that were originally there were railroad ties which failed years ago They were placed in the 1970s.at the time the home was built. We needed new retaining walls.

We obtained assessments Jeff from giant landscaping was most reasonable. They built up to retaining walls one in the front and the Other in back about 50 feet long both of them. They created a whole new look to the property. River rock was placed Below the Retaining Wall in the front with new plants. We are extremely happy with what was done. I would recommend this company. Great work. Guys

Working with Giant Landscaping was a pleasure. The crew of Kyle, Tyler and Kyle working on the granite stairs, mailbox and walkways were professional, detailed and always left behind a cleaned up area each night. Eric who installed our irrigation was extremely knowledgeable about the best way to set it up for coverage and zoning. If you're looking for a company that is reliable, efficient and knows what they're doing, Giant Landscaping is the one to call.

Giant was a subcontractor to another company I hired to do some brush removal. Giant sent Carl and Rick out to my house with the proper equipment to do the job. I was very impressed with these two young men. They worked hard during their 4 hour assignment and completed the majority of the work safely and on time. It was a pleasure working with these men. Thank you to Giant for a job well done!

The men show up, listen to me as what I wanted done and wasted no time to get started. They had done more in the allowed time then what I expected. Very professional people and very professional work. I would not use anyone else and not because of the price which is very reasonable but because of the quality of workmanship and the professionalism of the workers. I thank all of you and will be calling you back again and again and again.

I have never been so pleased. Everyone was so professional and helpful. From the salesperson, office staff and the installers. They did an awesome job and we're so pleasant. They showed up on time and cleaned up after. You could tell they took pride in their work. Highly recommend.

If it would allow zero stars I wouldn't even give 1. Giant Landscaping gave me one quote for a price after having employees walk my property, did the job and billed my credit card for over $200 more. When speaking with the owner he said they can't be held to the quote despite his employees saying how much labor and material it would take. He proceeded by encouraging me to fight the credit card bill as "they would get their money no matter what".

While the job they did on my lawn was nice they clearly don't care about customer service or saying whatever it takes to charge you. In addition it well over 3 weeks for them to finally arrive and do the job after telling me multiple times it was delayed the entire week due to rain even though it had only rained once during the week. I encourage you to find a lawn care company who won't treat you this poorly!

Giant installed my lawn sprinkler system. my lawn looks lush and green all season long. They also designed it right so that it doesn't saturate the shady areas, which was a problem before. This is a professional company who really knows their stuff!

Great customer service and outstanding workmanship! Jeff, Tim, and Laura addressed every concern that we had about paving our walkway and patio, planting flowers and trees, and Hydroseeding our yard. Jeff helped us create a vision for our backyard and I could not have asked for a better final product. The crews that came out were very professional, knowledgeable, and very polite.

Special thanks to crew members Kyle, Justin, and Erik for going above and beyond in making sure we knew what they were doing and making great recommendations. I truly felt that Giant Landscaping CARED about our home as much as we did. I highly recommend Giant Landscaping if you need landscaping/hardscaping done to your yard.

Awesome company with quick fast and friendly service from the person answering the phone to the tech that came out. We are first time customers who will now be loyal customers. Thanks for making my husband's day getting the irrigation system up and working. I think he is going to set the alarm to get up and watch it tomorrow morning he is so excited.

Giant Landscaping exceeded my expectations! My small yard had become something out of Jumanji. Taming it was simply too much for my husband and I to handle ourselves. Giant came out 2 days after I called them and the crew they sent was great. I explained what I wanted when they arrived and they were already hard at work by the time I grabbed my things from inside and left for work. I barely recognized the place when I returned. I couldn't have asked for a more thorough job.

Hiring Giant Landscaping was one of the best decisions I have made. I needed to hire a company with the reputation and the experience to accomplish a large scale redesign of our yard. Our project required various pieces of heavy equipment and a team of workers to make it all happen. After meeting with Jeff early on, I became confident that using Giant would be the right decision.

On our scheduled start day, I had the opportunity to watch Jeff supervise and delegate an efficient team that was professional, reliable and courteous. It was great to see the team members onsite early every day, working long hours and focused on what was in front of them. Frankly, I was impressed to see all that was accomplished each day. The significant transformation of our yard has added an amazing space that looks beautiful, brings functionality and has increased the value of our home. It was a smart decision and a great investment to use Giant. Hayden and Amy B.

Giant Landscaping has been absolutely fantastic to deal with! I am not a regular customer - as in lawn mowing, snow removal etc. I have them come to my house in the spring & fall for clean ups and they do a wonderful job.

Giant Landscaping was so pleasant to work with from the initial consult with Jeff all the way through each and every landscaper who walked onto our property. In particular, Jake went way above and beyond to be so kind, polite, and courteous.

Hi Jeff, We are very pleased with the way our retaining wall turned out. Your guys were able to replace the old wall without disturbing the plants that were right beside it, Amazing! We also love the slate they used to replace our rotting walkway.

For several years, we had a difficult time getting a large portion of our backyard lawn to grow back after some construction was done to our home. We hired Giant Landscaping to landscape a flower garden and fix the large portion of sparse lawn.

From my first meeting with Jeff, I knew he understood what I wanted for my walkway. He suggested the materials and a design that suited my needs and aesthetic taste. The walkway and cobblestone edging came out even better than I imagined.

Giant Landscaping just finished installing granite steps, front walkways, grill pad and sprinkler system. They did a great job, It looks awesome and we are very happy customers. It was not easy finding anyone who could remove old cement steps and put in a very large granite landing and steps.
