Here’s why we have a long list of returning clients

Hiring Lars was one of the best decisions we had ever made! Their team did an amazing job with our kitchen space, and we are so thankful for all the time they dedicated to us. They expanded our existing kitchen and updated the layout to be more practical and suitable for our needs. What we loved the most about them was that we were always included in the process and they had never missed an opportunity to check in and consult with us on the next steps.

With the baby on the way, we’ll surely need some extra space, and Lars Room Additions will be the first people we call!

Frequently Asked Questions

What are some of the best home additions?

The answer to this question depends entirely on your needs and the current design of your home in San Marcos. For example, maybe you want to add a bathtub spa, but your bathroom isn’t large enough to accommodate one. Or perhaps you and your spouse are having another child and you’d like to make sure the new family member has a room to call their own. 

The options are truly limitless. Of course, whichever one you choose, Lars Room Additions is expertly positioned to make it a reality. Some of the top home addition services we can provide residents in San Marcos and across the region include:

How can I prepare for a room addition?

Depending on the size of your San Marcos home and the scope of your project, you may or may not have to temporarily relocate your family elsewhere. However, if you have a large property that enables you to easily separate the construction area from the rest of the house, relocating may not be necessary.

Other things to consider when getting ready for a home addition:

  • Make sure your project complies with the relevant building codes
  • Notify neighbors and anyone else who may be affected by the noise from the construction
  • Construction sites can be dangerous for children and animals, so make sure your kids and/or pets can stay somewhere where they won’t interfere with the work

The experts who work at Lars Room Additions constantly keep up with building legislations and are able to provide recommendations on how to prepare yourself and your family for the upcoming project. When in doubt, don’t hesitate to get in touch with us.

How long does it take to build a master bedroom & bathroom?

Every home is different, and so is every project and the unique challenges involved in it. Factors such as the scope and complexity of your project, materials used, current labor availability, work organization, local building regulations, and various unforeseen circumstances can all have a huge effect on how long a home addition project will take. 

The best way to get a reliable timeframe is to reach out to Lars Room Additions and schedule an on-site consultation. Once one of our experts has assessed your home, they will be able to tell you how long your room addition in San Marcos will take. 

Does adding a kitchen increase value?

Absolutely. A kitchen is one of the most important rooms in a home, to the point where an outdated kitchen can put off prospective buyers while a modern, well-built one can almost sell a house all by itself. 

Kitchen updates that add a lot of value include:

  • Adding in a new kitchen sink
  • Updating appliances
  • Incorporating modern countertops
  • Putting in new light fixtures
  • Adding new hardware and repainting cabinets

If you’re not sure what the best way to upgrade your kitchen would be, feel free to reach out to Lars Room Additions. We’ll assess your current kitchen area and advise you on how to update it in a way that fits your needs and budget.

How do I choose a home addition company in San Marcos, CA?

Room and other types of home additions are a major home improvement project that should never be entrusted to an inexperienced or “budget” remodeling contractor. As a general rule, your home renovation company of choice should have decades of experience, be highly respected by its peers, and take great pride in its past projects.

Here at Lars Room Additions, we are all that and more. Our team of experts, project managers, seasoned designers, and trade partners is renowned for its skill and expertise. We were even one of the first San Diego remodeling companies to be certified by the National Association of the Remodeling Industry.
