We pride ourselves on the quality of our work as well as our commitment to outstanding results. We look forward to building lasting relationships and guarantee your satisfaction! We are a bilingual company, and are happy to serve both our English and Spanish Speaking communities! Please call Today!

"My husband and I had a ton of work done by Conber Construction and we couldnâ t have asked for a better experience. The scope of the project includes roof, windows, electrical work, exterior wall, tankless water heater, building a new gate, among other things. The project took a few months and it went smoothly the whole way through. Quality of work - Weâ re picky people. Between my husband and I, we checked everything with a fine tooth comb. And at the end of it, even WE were delighted with what we saw. Cesar does everything he can to make sure you're getting what you want. And he delivers. This was apparent from the very beginning. Heâ s got the experience and know-how to achieve what the customer wants, and he really cares that youâ re satisfied with the work. Price - Their quote was very reasonable & fair, and they stayed on budget. We definitely feel we got our money's worth. Strong communication - Customer service is very important to me. Iâ m happy to say, these folks are very responsive. I could reach out at any time with questions or comments and felt very supported throughout the whole process. Even at the very end (when some contractors can peter out), Conber was with us the whole way through. You just donâ t see this kind of customer service anymore. Ideas - When we were stuck and looking for ideas, Cesar and Fabiola were always so helpful. Between Cesar sharing what he has done on other projects, and Fabiola searching for ideas & possibilities online, we got great guidance from them. Construction crew - All their workers were very nice and & respectable. I felt very safe with this team in and out of our house (even during covid!). Very clean, neat & tidy. This is important to keep neighbors happy. Flexibility - We added projects along the way and they were very accommodating. Overall - Our entire experience went so well! The house has been transformed and weâ re constantly getting compliments from the neighbors and friends as they come over! We plan on doing more work on the inside of the house next year and we will, for certain, be reaching out to Conber Construction. Highly, highly recommended."

Addition to existing structure building services FAQs

Converting an existing space into a laundry room is more affordable than building a new addition. While new additions start at $5,000, renovating an existing space for laundry use can begin at $1,300. 

Your specific costs will depend on whether plumbing and electrical connections exist nearby, the quality of finishes you select, and whether any structural modifications are needed. Always budget extra for unexpected issues, particularly in older homes where hidden problems might surface during renovation.

The smallest practical size for a new laundry room addition is 35 square feet, which provides enough space for basic appliances and minimal storage. For renovations utilizing existing space, smaller footprints might work with space-saving solutions like stacked appliances. 

A standard-sized laundry room of 60 square feet offers more comfort and functionality, allowing for counter space and storage cabinets. The optimal size depends on your household needs and available space.

Yes, adding a laundry room requires several permits, particularly for new additions. You'll need building permits, plus specific permits for electrical work, plumbing installations, and possibly HVAC modifications. 

Requirements vary significantly by municipality, so consulting with your local building department before starting work is essential. Proceeding without proper permits can result in fines, mandatory removal of completed work, and complications when selling your property.

The timeline for completing a laundry room addition varies based on project complexity, contractor availability, and permit processing times. Factors that can extend the schedule include material delivery delays, weather conditions, and unforeseen structural issues discovered during construction. 

Renovating an existing space often requires less time than building a completely new addition. Working with an experienced contractor who can coordinate various tradespeople efficiently helps keep your project on schedule.
