The initial salesperson Mark had a good line of BS, but the material called out on the original design I signed off on and received was replaced with much cheaper and lesser material. When I asked Mark about how my site was left, he did not have a clue. None of the scrap materials were...

Unresponsive communication and repeated broken promises. Here is a classic example of someone who cannot be taken at his word. We agreed in the fall of 2016 that the job porch construction would start in the spring. I reached him in April and he said he was “finishing up a roof, which would...

"They went above and beyond for our project. They did exactly what we wanted and more. They even went as far as helping get some debris moved for us while they had their equipment out here. They built us these two beautiful rock retaining walls with ramps down the center and even went above and beyond by adding gravel to the second/third tier when I had mentioned I wanted to do it in the future. Their pricing was fair and they even helped out my mother in law to do some work. *If I could post a photo I would, but the file size is too large*"

"The job was clearing out a 300 sq foot area of tree roots, prepping area for new driveway, and laying down new asphalt. The job with Dennis started out great. He worked very hard. When it came time to get asphalt for the driveway, the shop just had 1 variety that day. When he arrived at my house with the asphalt, he was visibly upset about the grade that they had available. He made the decision to get a grade that has rocks in it that are from .5"-1" size rocks. Definitely not a finer grade which is more acceptable for residential driveways. When he was done, he was still visibly upset about the results and even thanked me for not being irate with him. He was hiring a third party to come in and lay mastik to fill the gaps, and level the surface, then seal the entire driveway. I appreciated his hard work and believed he was taking care of the job, so I paid him since I felt he was a man of his word. I even gave him a $600+ tip. The mastik/sealing company came out the next day and only used mastik on 25% of the 300 sq feet. A few days after it was fully dry, I texted Dennis and expressed my concern that the gaps were not filled and the surface was not at all level. He agreed to have the sealing company come out again. I specifically asked Dennis if they were using mastik as another coating of seal would not fill the gaps. He ignored my question and a second layer of seal was applied. I texted Dennis after the weekend asking him to get back to me. I did not hear back from him. I texted the next day expressing my concern that the gaps were still not filled and that now, there were streaks from the second application of the driveway being sealed. I included photos and asked him to please get back to me. He said that the work was "not that bad" and he "did what was on the estimate". "If the work is unsatisfactory, then I recommend going with another company" I paid Dennis for his hard work and what I thought was his honest word about finishing my driveway. Definitely my fault for believing him at his word. Dennis was dishonest with me on many occasions. He said that mastik would be used to fill gaps and level the surface. That did not happen. When I repeatedly brought up the grade of asphalt that he chose without talking to me, he said "asphalt is aphalt" that there is no difference in grade. Dennis told me that he would come out and look at my driveway again, but he never did. Dennis claimed that he sent the company out to seal my driveway 3 times and it was twice. I know that this repair would not match my existing driveway, but asphalt that was a much more appropriate grade could have and should have been used. I will have to hire another company to rip out and redo what Dennis refused to complete as he told me. I'm sure most of the time Dennis has done great work. Unfortunately that was not my experience. I thought he was a man of his word, but his dishonesty and bad decisions have left me with an unacceptable end result."

FAQs for retaining wall installation projects in Roslyn, WA
Landscapers typically charge $25 to $50 per person per hour, which equals around $50 to $100 per hour for a two-person crew. These rates can vary depending on your location, the size of staff needed for the job, and overall job type. For example, a larger crew will be needed for structural additions and hardscaping versus planting flowers.
When it comes to landscapers, licensing laws vary. Landscaping architects are required to be licensed in all 50 states, whereas traditional landscaping contractors are not typically required to hold a certification. You’ll likely be working with a landscaping contractor for most residential projects. If you are redesigning your whole yard or adding in hardscape features, you will work with a landscaping architect at some point during the project. Be sure to check our state licensing tool to review the local landscaper guidelines.
As you browse our pro listings, take note of the “Angi Approved” badge. Angi Approved businesses meet our standards for certification which include:
The owner, principal, or relevant manager passed a criminal background check
Required to have applicable state and local licenses
Maintain an average star rating of 3.0 or better on our network, if they have at least one review
Paying to advertise their services
Meeting any other eligibility criteria required by Angi
Keep in mind licensing is different from certifications. A license is a legal requirement to operate a business, while certifications are voluntary.
A paver patio can last anywhere from 20 to 100 years, depending on the type of pavers and how well you maintain them.
Travertine pavers are usually the most durable, lasting 100 years or more, with regular maintenance. Concrete brick pavers have a variety of shapes and colors available and typically last 25 to 50 years. Traditional brick pavers have a more classic look, lasting around 20 years with proper maintenance.
Landscaping costs around $3,500 but varies widely from $200 to $14,000. Factors that play a part in your final landscaping price tag include:
Location
Yard size
Project size
Materials
Land preparation
Type of landscaping
Considering so many factors, it’s not surprising that the overall costs can differ. A typical landscaping project is flower bed installation, which averages between $800 and $3,000. However, landscape lighting installation is a higher-end project, with a price tag of $2,000 to $6,000.
The cost of a paver patio is $3,800 for a 280-square-foot patio on average. Depending on the patio size, paver material, and design complexity, this cost can range from $2,400 to $7,000 or more.
The size of your patio is a significant factor in the project’s overall cost. If you're building a smaller patio of only 60 square feet, your costs will be closer to $480 to $1,500. If you want a more luxurious 900-square-foot patio, you'll spend closer to $7,200 to $22,500.
