"Emanuel was a pleasure! The job was completed in one day and they turned out beyond my expectations. Emanuel followed through completion. I will use Forefront again should I need other home repairs and I highly recommend if you are looking for a professional who takes his time listening to you needs. I would give Forefront 6 stars!!"

Additions & remodels
"We've worked with Eli Resendiz and his team on a bunch of projects around our place over time, and they've handled every single one well. Dry rot repair, trim work, rechalking, stair fixes, fencing, you name it, they've taken it on without any issues. What stands out most is how easy Eli is to work with. He communicates clearly, shows up when he says he will, and just gets the job done right the first time. You don't have to babysit the work or worry about corners being cut. His team can pretty much handle anything you throw at them, which is rare these days. Whether it's a small fix or a bigger multi-part project, they figure it out and deliver solid results every time. If you're looking for a contractor who's reliable, skilled, and genuinely good to work with, Eli is who you want. We wouldn't hesitate to call him again for future projects."

Frequently asked questions
- It’s important that you verify their license is still in good standing. Also keep in mind that certain states or provinces don’t require licensing if the job is under a certain dollar amount.
- You can find a list of your state’s licensing requirements on the HomeAdvisor website. Before you get to work with the pro, make sure their qualifications are current and acceptable to you.
- It is always a good idea to get a copy of the pro’s insurance certificate for future records, and in case anything happens. This is a good way to feel more secure in your home project, and to weed out potential scammers.
HomeAdvisor makes it easy to connect with pros near you. You can read reviews, get quotes and book appointments all in one place.
Depending on the type of project, you may find subtle differences in the hiring process. Here’s a look at task-specific advice.
You can use HomeAdvisor to help evaluate a contractor’s qualifications. We put pros through a screening process, and award badges to high-performing contractors. You can find these badges on a pro’s HomeAdvisor profile, and sometimes, his or her website.
Your research doesn’t stop here. Once you’ve found a few prospective companies, make an call to ask a few questions about work history, licensure and more:
- Have you completed a job like this before?
- Do you have a list of references I can contact?
- When are you able to start the job?
In most cases, the responses you get to these three questions will give you a very good idea of the right pro for your project. If you have more than one front-runner, these additional questions can help you narrow it down.
- How many years of experience do you have?
- What’s your permanent business address?
- Are you licensed to work in my area?
- When did you earn your business license?
- How do you handle warranty service complaints?
- Do you have worker’s compensation, property damage and personal liability insurance?
Any good contractor will answer these questions, and most will appreciate dealing with a client that takes such an active interest in finding good service. On the other hand, if a contractor gives you a hard time with these questions, you probably want to find someone else.
