Main Line Kitchen Design is a unique business model that specializes in complete kitchen renovations only. We are experts at pricing out your kitchen project simply by asking you questions during a detailed phone call. We are 5 skilled Kitchen Designers with many years of experience planning kitchens around the Delaware Valley. And we are cabinet dealers for 8 nationally distributed cabinet lines much like traditional showrooms. Unlike full showrooms open to the general public, Main Line Kitchen Design works only by appointment. Appointments can be scheduled days, nights, and weekends either in your home or in our office and selection center. During office appointments we display clients kitchens on a flat screen TV and help them look through 100’s of sample door styles, almost a thousand sample finish blocks and sample kitchen cabinets. During home visits we can bring samples, take measurements, and make design changes on laptops showing you what your kitchen can look like in the very room being renovated. This is more convenient for our customers and it eliminates the expense of staffing and maintaining a larger space that is open to walk in traffic. We pass the significant savings on to our customers and so we sell cabinetry for less than other dealers, even home centers like Lowes and The Home Depot. Call today for a detailed estimate on your project over the phone.

"We reached out to Paul and his team at MLKD for help with our kitchen remodel, and they were so professional and detailed during our initial consult that we hired them right away. The MLKD team worked with us tirelessly to make the perfect design and also ensured the procurement and prompt delivery of our cabinets. They also recommended an excellent installation contactor, and we were just thrilled with the end product. Thank you Main Line Kitchen Design!"

"We used to love this service and gave them glowing reviews on Google in the past, but something has changed. Their customer service sucks, they don't apologize, don't call back etc. We had a hot water heater installed 2 years ago. It is still under warranty. Yesterday, 11/9/25, it broke and started leaking badly - still under a warranty from them. A.J. Perri advertises as they are 24/7 company, but they would not come yesterday and would promise us that first thing this morning, at 8 am, they would be knocking on the door. They never came, never called and never apologized. In fact, they have an attitude for misleading us and at 10 am mo one is here. The technician (do they only have 1 technician?) Is over 1 5 h away at another job. Customer service sucks with them really badly and now I feel as because we called them and voiced our dissatisfaction, no one will reach out to us or help us, while we are covered by their warranty. We had to pay for another service last night to pump"

FAQs for second story addition building service projects in Lawrence Township, NJ

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.
