"Ezra and Charles are very friendly and personable. That is, when they want to take your money. What good is a 12-year warranty if you start ignoring your customers at 2 years. I needed my HVAC replaced. Because the HVAC sits on my roof, I decided to redo the roof too. Ezra and Charles came out and were really friendly so I immediately had a good impression of them. Even though it would’ve been cheaper to go with a roofer and a separate HVAC company, I decided to go with Landmark Construction Crew, aka Landmark Energy Upgrades. I figured it would be a more seamless process for one company to do both. I got this done in December of 2016. The thing with a roof is that you don’t know if it’s a good job or not until it rains so I waited to write a review. Around January 2018 ( a little over a year later ) we got some much needed rain but unfortunately, I had a leak coming from one of my vents. I emailed Ezra and he sent out a roofer. The roofer came, looked at the vent, jumped up on the roof for ten minutes and said he was done. Months later, it rained again, it leaked again, I emailed Ezra again. I decided to take a closer look at the vent and noticed that there was sunlight in the ductwork. I figured sunlight equals gap somewhere. When the roofer came, I told him and he said it’s nothing, probably just a reflection, without even taking a look. Then the roofer tells me that the next time there is a leak, I need to call the HVAC guy because it’s not a roof problem. I couldn’t believe it so I told him that HIS company IS the HVAC guy!! I used one company to do the roof and the HVAC so there is NOBODY else to blame. So, he jumps back on the roof and was done and gone in 10 minutes. About a month goes by and the rain is back and so is my leak. It’s 2019 so it rained a lot this year. Good for California, bad for me. So, I emailed Ezra again. After a few weeks, no reply. So, I email him again with pictures, a few more weeks go by and no reply. So, I call him and he picked up the phone. He sounded surprised to hear from me (probably didn’t recognize my phone number) and I start telling him about the leak. He said he didn’t get my emails but just text him my address and he’ll send somebody. A couple of weeks goes by and nothing. So, I text him again and after weeks and weeks of waiting, no reply. I’ve emailed, called, and texted so, at this point, it’s very obvious he’s avoiding me. If you are looking for a friendly company that is willing to take your hard-earned cash then Landmark is for you. But if you’re looking for a company that is accountable for their work then look elsewhere. I know I am."

Pacific Coast Termite Inc
Pacific Coast Termite Inc
Pacific Coast Termite has a great history serving California since 2007 by co-owners Dennis Wilson and James Grande. Both men agree that a large part of their company’s growth is attributed to word of mouth and referrals along with great reviews and A+ rating with the Better Business Bureau have also helped. Today the company has full in-house wood working divisions, offers comprehensive termite control, rodent control, and attic services such as attic cleaning and TAP pest control insulation to replace old soiled attic insulation.
"Horrible experience, the employees were very poorly trained. They severely underestimated the time to do the job. They sealed holes in vent screens with big globs of unsightly goo. The crawlspace access door wouldn't stay closed do they pried a stepping stone out of the garden and used that to hold it closed. They spit sunflower seed shells all over, including on our front porch furniture. They vacuumed the old insulation out of the attic but there was a leak in their system and it spewed old insulation and rat droppings all over the inside of our garage and on open storage shelves, and they didn't clean it up. They only apply blown-in insulation and our ducts are covered with sheet insulation, so they didn't remove that insulation or the rat droppings on the tops of the ducts. I could go on...."

General Contractor
FAQs for contractor service projects in Janesville, CA
Generally, general contractors charge between $50 and $150 hourly, though not every contractor charges by the hour. If charging based on the project, you can expect a markup of 10% to 20% of the construction cost. You can expect to pay between $300 and $500 daily if charged by the day.
General contractors are the ones that coordinate home construction projects. They are in charge of the day-to-day oversight of the subcontractors to ensure that the project is completed on time and to resolve problems as they arise. General contractors:
Complete pre-construction planning, both with the customer and crew
Provide realistic cost estimates
Develop construction timelines
Ensure deadlines are met
Acquire permits as needed
Purchase supplies and materials
Before hiring a general contractor for your home project, it’s a great idea to write down a list of questions to discuss with each prospect. Some example questions to get you started include:
Which types of insurance do you carry?
Can you provide a list of references?
What is the expected timeline for this project?
How will my project be supervised?
Will you hire subcontractors for the job?
What is the best way to communicate changes?
Will you obtain all of the required building permits?
While city and state laws vary on general contractor licensing requirements, hiring an unlicensed general contractor could lead to poor quality work, costly future expenses, and potential code violations. Be sure to check our state licensing tool to review the local general contractor guidelines for your area.
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.
Yes, most general contractors require a down payment for project completion. A reasonable down payment for a contractor is 10% to 25% of the total project cost, though that will vary based on project size and location. The down payment helps cover the upfront costs of materials and permits and helps ensure payment for the project at hand.
