"Zero stars if it were possible. Harry M came to my home and quoted me 200 dollars and cash was the only payment option he would accept. He came that Saturday and did a horrible job. He used my mower and it’s not working properly now. He didn’t have a working weed wacker and asked for my personal one. He left so many areas undone and I he did report he would come back to finish the job. This never happened; he kept saying he had me scheduled but forgot to tell me. A crew was supposed to come two Saturdays ago and this never happened. He does not respond to text messages. Most importantly, he asked to come to my house to BBQ and to date me. I have text messages to prove this. Even after I declined, he didn’t not understand no after being told several times. There’s a review on another site that doesn’t remove negative feedback and he called that person cursing them out and verbally threatening them. If he does this to me, I will immediately press charges. I’m reporting this fraud anywhere I can until I get my money back from this fraud."

"I contacted Josh at C3 for a quote to prepare and build a flat, level, 18' by 14' base on a slope framed with 3 levels of 6 x 6 timbers to retain 3 individual layers of premium quality aggregate for superior drainage and soil stability. His design was to insure the driest base environment to install a shed that will last far longer than other contractors I spoke with. I couldn't have been happier with my choice of C3. He and his crew were very professional and detailed in the work performed. Always on time and mindful of the surrounding work area and exceptionally detailed in their final cleanup of the site. I would recommend Josh and his company for this type of work and larger projects due to his commitment to excellence and customer satisfaction."

Arborists questions, answered by experts

On average, a prefabricated pergola kit takes one to four hours to build. Prefabricated pergolas are the fastest to install and could save you money, while custom pergolas can take several days to install, ranging from eight to 16 hours. The number of workers on the project can also impact how long it takes to install a pergola. 

If you need to build a concrete slab, level your property, or remove obstacles from your yard before building a pergola, then your project could take several weeks to complete.

Other projects that you can do at the same time as your trellis include painting the deck , installing a pergola, or adding mulch to your garden beds.

If you are installing a fiberglass pool, you may want to install or update your patio or deck at the same time to create a safe, comfortable place to sit and dry off or grab a bite to eat after swimming. You might also consider adding a hot tub to the mix, which costs $6,000 on average.

Pergolas have no base structure to hold them up, so it’s necessary to attach them to some type of foundation. Most pergolas require a minimum of at least four concrete footings to keep them solid and stable in the ground. Attaching the pergola to a concrete foundation is an option as well.

Wooden pergolas can last five and 12 years as long as you maintain your pergola. Make sure to clean, stain, and seal wood pergolas every two to three years to protect the wood from insect damage, rot, and decay. 

Vinyl or aluminum pergolas can last a lifetime. The only problems you may encounter with these pergola materials are weather-related—heavy rain storms or snowfalls. Check the stability of your pergola every season. You may need to add new supports or replace broken beams on an as-needed basis.
