Christine Brotschul


We had a wonderful experience using the A.M. Pellak Construction team. We renovated our kitchen/ family room/ dining room area to create an open floor plan. In addition, we installed a new patio, siding and windows throughout the entire house. From beginning to end, the project was managed and executed in the most professional manner.

The entire team was knowledgeable, polite, professional and readily addressed our concerns. It was also the cleanest construction project we have ever experienced. 

The level of customer service we received was 5 stars. We love the outcome of the project(s). We will absolutely use them again as well as recommend to family and friends.

Different Home Additions Cost In Newtown Square, PA

The Cost Of A Deck Addition

Transforming your home by constructing a deck is an incredible way to add value, and it’s one of the most budget-friendly investments you can make. It won’t break the bank either – prices typically average between $20-$50 per square foot!

Rather than opting for softwoods such as pressure-treated wood, cedar, or redwood, we suggest composite or hardwood. Trex and TimberTech are two amazing choices of composite decking brands to consider; on the other hand, if you want something more luxurious looking, opt for Ipe, mahogany, tigerwood, or teak hardwoods instead.

However, for customers here in Pennsylvania, the best all-purpose solution is composite wood decking, simply because these structures will last way better in PA’s climate.

Generally, a small wooden deck can cost approximately $10k, but a larger, two-level composite deck with premier railings and lighting may reach up to $50k.

The Cost Of A Walk-Out Basement Addition

Building a walk-out basement can be an intensive and pricey task. Generally, the most affordable choice starts around $20,000, while more extravagant renovations may cost up to $50,000! However, a finished basement typically returns an ROI ranging from 60% to 70%.

For every dollar you invest in a finished basement, you’ll get around $0.70 back when it’s sold.

The toughest part about building a walk-out basement is that you’ll need a slope to build it. Otherwise, getting an excavation service will pump up these prices, and you’ll spend much more than you initially wanted.

The Cost Of A Garage Addition

Building a garage is around $40 to $50 per square foot for basic construction.

If you’re pondering the addition of a garage to your home, keep in mind that the cost can differ drastically depending on size and design. As a rough estimate, constructing one-car garages typically costs anywhere from $12k-$17k, while two cars will require an approximate expenditure of between $18.2K – 25K for installation.

Whether it’s a detached or attached garage, this investment will be well worth it. In fact, even just replacing a garage door will bring a return on investment of over 90%!

The Cost Of A Sunroom

A sunroom might be the ideal addition if you’re searching to invest in your dream home. The cost of materials and installation varies from $27k – $58k, with an average of about $130-$330 per square foot.

If you’re looking for an affordable and simple solution, pre-fabricated sunrooms can be quickly installed with minimum effort. Nevertheless, building one is the wiser choice if you want a more long-lasting option that offers maximum value for your money!

No matter what option you’re going for, working with a professional contractor will make your project much smoother, and you’ll enjoy a quality installation.

Three Things To Keep In Mind For Your Home Additions Cost In Newtown Square, PA

The home addition market is rife with unscrupulous contractors, all too happy to exploit homeowners who are desperate for help by providing a low-quality service and then disappearing without a trace.

Here are three things worth remembering when budgeting for your home addition project.

Setting and adhering to a budget is essential for any financial plan, which means it’s critical to discern between what you need versus what you merely want.

For example, does a three-car garage make sense if you only own one vehicle? Is an expensive kitchen expansion necessary when your current space already provides ample room for dining?

You get the idea. Don’t overspend on things that won’t help you, and don’t understand on upgrades that you know you need.

Preparing for unforeseen events when remodeling or building is crucial.

Once in a while, you may discover distressing issues such as mold and mildew or plumbing problems within your home. It is critical to act quickly in order to resolve these matters. To ensure your project’s success, set aside an extra 20% of the total cost to deal with these issues.

As we said, the remodeling market is full of bad practices and contractors going after your money.

Taking the time to do your due diligence is essential when deciding on a reliable contractor. Thoroughly scour online reviews, examine their past projects, acquire an estimate from them, and quiz them with plenty of questions to decide if they are dedicated to procuring you as their client. By doing this, you can make sure that the decision you will be taking is well-informed.
