"Don’t use Triple A Air Conditioning & Construction! Also AAA Construction same company Zee Armand (AKA Zahid Hussain) of Triple A Air Conditioning & Construction took our deposit didn’t do the work and left the siding off our house! We found Zee Armand (AKA Zahid Hussain) on Porch.com and asked him to give us an estimate on removing some dry rot, replacing a shower in our guest bathroom and installing some sheet vinyl in both the guest and master bathrooms. The estimate for the shower seemed reasonable, but for the flooring he was charging over $20 per square foot and we had already purchased the flooring ourselves. From Home Advisor: Installing sheet vinyl costs around $3/sf. Installing luxury vinyl tiles (LVT) or planks (LVP) costs considerably more, hovering at $7 per sq. ft.. Zee was the third contractor we had out to look at the bathroom and so by that point we were stressed and frustrated and after negotiating the flooring price down, we still decided to use his services and paid him a 10% deposit of $500. He was then supposed to come over the next day with his helper to look at the job and determine the tools they would need. He cancelled due to rain and said he would start on Monday instead. He arrived on Monday with his helper, took off a couple pieces of the siding of our house to expose the dry rot and told us that he was going to Home Depot to get supplies and update the estimate. He said he would be back in the afternoon and around 2:00 he still wasn’t back yet, so we contacted him to find out what was going on. At that point he proceeded to tell us that because of the little bit of mold that was there, that if a mold remediation team came out to remove it would cost us over $5000, but that he could do it for $1550. At that point we cancelled the job and demanded that he return our deposit. Long story short, he never gave us our $500 deposit back. Upon further investigation it was found that he has had numerous small claims judgments against him. He is also operating without a Home Improvement certification and isn’t certified to remove mold!"

FAQs for second story addition building service projects in Valencia, CA

For many homeowners, building up is worth the expense because it provides the extra bedrooms or living areas that can’t be accommodated within the existing footprint. A larger, updated home often commands a higher resale price, recouping a sizable share of the project cost while allowing you to stay in the neighborhood you love. Run the numbers with a real estate agent and contractor to ensure the expected return and day-to-day benefits align with your goals.

Whether it makes more sense to build up or out depends on your lot, budget, and local code. Building up preserves yard space and involves less foundation work, but you may need to vacate the home during construction. Building out avoids staircases and can proceed while you stay put; however, it encroaches on the yard and may face setback limits. Compare both options with your contractor before making a decision.

A structural engineer will first inspect the existing foundation for cracks, footings, and load capacity. Depending on the findings, the crew may pour new concrete footings, install steel or concrete piers, add reinforced beams, or tie additional rebar into the slab. These upgrades redistribute the weight of the new floor and bring the structure up to code. Your contractor will outline the specific reinforcement plan and timeline once the engineering report is complete.
