At HavenHub, we're more than just a home service company – we're your trusted partner in creating havens of comfort and joy. Specializing in several verticals such as Landscaping, Landscape Architecture or Design, Masonry/Concrete and much more, we bring expertise and dedication to every project we undertake. What sets us apart is our commitment to putting our customers first. From the moment you engage us, you'll receive world-class service where your needs drive the project. We don't just build landscapes; we build relationships founded on trust and meticulous execution. At HavenHub, your satisfaction and peace of mind are our top priorities, and we're honored to be a part of your home journey. Welcome to the HavenHub family, where your home is our passion.

"I truly regret hiring HavenHub for my backyard project. After a salesman came to our door, he designed our landscaping plan — retaining wall, stairs, shed pad, boulders, and sprinklers — and quoted $24,995. I paid in full around July 8, 2025, with a contract promising completion by July 28. No one ever showed up until I contacted them. Since then, I’ve dealt with four project managers, endless delays, broken promises, and almost zero communication. One crew came but didn’t know what they were supposed to do and couldn’t reach anyone for direction. Another poured a footing wrong, according to one of their own workers. Months later, my yard is still torn apart, and HavenHub continues to ignore me despite taking full payment. I’ve had to involve a lawyer just to try to get a response. Terrible communication, unreliable crews, and no accountability. Be very careful before hiring this company."

Satisfaction guaranteed! I chose to work in this industry because I began my career working for several large companies, at which I realized the significant cost of landscaping and outdoors development . Considering how expensive these were for homeowners, I decided to open up my own designing company to provide eco-friendly landscaping design at a much lower price. I vowed to provide only the best customer service and care to keep my clients satisfied. We started in this industry in 2004. We describe our business as Rooted in the community. HOW DO YOU TREAT YOUR OWN CUSTOMERS? THE WAY YOU WANT TO BE TREATED. WORKING WITH ALL THE RELIGIOUS ORGANIZATION WORKING WITH LARGE COMMUNITIES ( H.O.A. ) WORKING WITH PET OWNERS AND KINDER GARDENS WORKING WITH SENIOR CITIZEN COMMUNITY

"Hutch was professional and personable , easy to talk to about my design for front yard. His experience in design suggested minor adjustment of my idea/drawings but willing to landscape any way of my preferences. His contract was thoroughly itemized and didn’t add any additional “surprise” costs. Payments were installments as project progressed. Hardworking Crew stayed on expected timeline. Hutch came by every day to supervise progress of our landscaping. Our front and backyards were transformed from weed fields into beautiful landscaping. Removed weeds and unwanted plants, prepped surface, laid weed barrier and installed Artificial turf in backyard, laid pavers and stone walkway. Transformed front yard into rock riverbed surrounded by plants accented with boulders, and installing drip system. Planted border shrubs and a rose garden. Lined walkway and rose garden with pavers matching our flagstone. Our sewer line needed realignment which Hutch arranged to be repaired. Other company estimate quotes were either vague, didn’t itemize, or way over priced. Offered a few addresses for us to drive by to see his actual work which helped us on our decision to work with Hye Turf Design. I would highly recommend Hye Turf Designs. Thanks Hutch !"

FAQs for engineer structural projects in Duarte, CA

The timeframe for installing an LVL beam depends on your project's complexity and scope. Factors affecting the timeline include whether walls need removal, the beam's size, and whether electrical or plumbing modifications are necessary. Your contractor should provide a specific timeline estimate based on your home's unique circumstances and the specific requirements of your installation.

Financing options are available for structural improvements like LVL beam installations. Many homeowners use home equity loans or lines of credit, often offering favorable interest rates for home improvement projects. Some contractors partner with financing companies to provide payment plans directly. When gathering quotes, ask potential contractors about financing partnerships they maintain or recommendations for lenders experienced with home renovation projects.

LVL beams become necessary when you need to span greater distances without support columns or when supporting substantial loads. Traditional lumber can't span more than eight to 12 feet without support, while LVL beams can extend up to 30 feet. LVL provides the necessary strength to create truly open concept spaces or support upper floors without columns. Consulting with a structural engineer helps determine the appropriate beam type for your specific requirements.

Beyond the core installation, the budget for build-back costs totals $400 to $2,000, depending on the extent of affected finishes. If foundation reinforcement becomes necessary, allocate $1,000 to $3,000 per pier. Permit fees ranging from $100 to $500 should also be anticipated. For installations affecting utilities, factor in electrician rates of $50 to $130 per hour and plumber rates of $45 to $200 per hour if rerouting is required.
