Any Home Additions Will Do

We got you covered on any addition to your home

Adding a room to your existing home or building a separate structure can seem like it will be very costly and time consuming. But that’s not true if you hire the right contractor.  Our expert project managers and years of experience combined with skillful craftsmanship are here to make all your home addition dreams come true with ease and on budget. When it comes to your home, you should never settle for less, because it will most likely cost you later on. Maingreen Remodel & Construction is considered one of the best in the business in the Greater Los Angeles area, offering also premium bathroom and kitchen remodeling. We will tackle your job and seamlessly handle it from planning to demolition to construction, and we keep you in the loop every step of the way.


We turn garages into beautiful one bedroom apartments that can be rented out. If you prefer to leave your garage as a car and storage space, we can help you create a clean, updated look.

Extra Rooms

Whether you want to host your in-law or  make extra income with an AirBnb, we can help you create a beautiful guest space.

Green House or Garden

Ever dreamed of growing your own food or herbs, like lavender, dill and mint? Fresh tomatoes or lemons off a tree? We can make your greenhouse or vegetable garden come to life, so your health can flourish too!


The patio is an important place to sit and connect. Whether your dream is to enjoy a romantic evening under the stars or play cards in the sunshine with extended family, we create the space so you can create your memories.
