What Is a Professional Services Agreement?
Aug 20, 2026
One of the first questions we hear when someone is considering a remodel is pretty straightforward:
“How much is this going to cost?”
Fair question.
If you’re thinking about remodeling your kitchen, bathroom, basement or a large portion of your home, you need to know whether the project you’re imagining makes sense for your budget. The tricky part is that there can be a big difference between having an idea for a remodel and having a project that is developed enough to accurately price.
That is the purpose of a Professional Services Agreement, often called a PSA.
A PSA gives us the opportunity to work through the design, scope, selections, specifications and other important details before we prepare the final construction agreement.
In simpler terms: we plan the project before we build the project.
So, What Exactly Is a Professional Services Agreement?
A Professional Services Agreement covers the design and pre-construction work required to turn your initial remodeling ideas into a much more complete project plan.
When you first contact us, you may know that you want a larger kitchen, a better primary bathroom or a completely updated main floor. You may even have inspiration photos and a pretty good idea of the style you like. That gives us a great place to start, but there are still plenty of questions to answer before anyone can responsibly give you a final construction price.
During the PSA phase, we begin working through those details with you. Depending on the project, that can include design development, a detailed scope of work, specifications, material and fixture selections, budgeting, value engineering and coordination with other professionals when needed.
The goal is to replace as many assumptions as possible with actual decisions.
Why Can't We Just Give You a Final Price Right Away?
Because we’d rather give you a realistic number than a quick one.
Take a kitchen remodel as an example.
Are we keeping the same layout or moving plumbing? Are the cabinets stock, semi-custom or fully custom? What appliances are being used? Are we changing the flooring? Removing a wall? Adding lighting? What countertops, fixtures and finishes are going into the room?
Those decisions can make a pretty significant difference in the cost of the project. The same thing happens with bathrooms, basements and whole-home renovations. A contractor can usually give you a preliminary idea of where a project may fall based on the information available, but there is only so much accuracy possible when major details haven't been decided yet.
We don't want to build a proposal around a bunch of guesses and then spend the rest of the project explaining why the price keeps changing.
We'd rather do the homework up front.
It Starts With Understanding What You Actually Want
Our process begins with a conversation.
Before we start drawing plans or choosing finishes, we spend time understanding how you want your home to work.
What isn't working right now?
What would make the biggest difference in your everyday life?
How do you use the space?
What style are you drawn to?
Where do you want to invest, and where are you comfortable keeping things simpler?
Those conversations matter because two homeowners can remodel nearly identical spaces and want completely different results. One family may care most about creating a kitchen that can handle a house full of people. Another may want custom storage and high-end appliances. Someone remodeling a primary bathroom may dream about a large walk-in shower, while someone else would never give up the soaking tub.
There isn't one correct way to remodel a home.
The PSA gives us the time to figure out the right way to remodel yours.
Then We Develop the Scope:
Every remodeling project is different, so the exact services included in a PSA will depend on the size and complexity of the work. A smaller bathroom renovation may require fewer design and planning hours than a whole-home remodel involving structural changes, custom cabinetry, multiple rooms, and outside engineering.
In general, the pre-construction phase may include the following areas:
Developing the Design
This is where your ideas begin taking shape.
We consider the existing space, your priorities, and the way you want to use the finished room. The design may address layout changes, storage, traffic flow, architectural details, fixtures, lighting, finishes, and how the remodeled area connects with the rest of your home.
Our design-build approach allows the design and construction sides of the project to remain coordinated. When additional professionals are necessary, we can help facilitate work with preferred designers, architects, engineers, and other specialists. You receive one primary point of contact rather than being left to manage several disconnected providers on your own.
Defining the Scope of Work
A complete scope of work explains what will actually be included in the remodel.
For example, “update the bathroom” could mean replacing a vanity and fixtures, or it could involve reconfiguring the layout, relocating plumbing, building a custom shower, installing new cabinetry, and changing the lighting.
Those are very different projects. The PSA gives us the opportunity to document the work in greater detail so you can understand what is included before signing the construction agreement.
Choosing Materials and Finishes
Material selections affect the appearance, performance, price, and schedule of your remodel.
During pre-construction, we help identify the fixtures, finishes, and products needed for your project. Depending on the space, this may include cabinetry, countertops, tile, flooring, plumbing fixtures, lighting, hardware, appliances, and architectural details.
Completing these decisions early helps us price the correct products and plan around their availability. It also reduces the risk of rushed choices and preventable delays after construction begins.
Developing the Budget
As the design, scope, and selections become more specific, the budget becomes more reliable.
We can compare the developing plan with your priorities and investment goals, then make thoughtful adjustments where needed. This may include revising part of the scope, considering a different material, or identifying where a larger investment would make the greatest difference.
This process is sometimes called value engineering. It is not simply about making everything less expensive. It is about finding the strongest balance between cost, quality, function, and the finished result.
Coordinating Technical Services
Certain projects require services beyond standard design and estimating.
Structural changes may call for engineering. An addition or complex remodel may require architectural plans. Some projects need surveying, investigation, renderings, permit preparation, or limited demolition and discovery. When those services are necessary, we help coordinate them as part of the larger project-development process.
What Is Demolition and Discovery?
Not every important detail is visible during an initial walkthrough. Existing plumbing, wiring, framing, water damage, or previous construction work may be concealed behind walls or beneath finished surfaces. In some cases, limited demolition or discovery is needed to better understand those conditions before the final project price can be established.
Performing that investigation during pre-construction can help uncover relevant information earlier, when it can still be incorporated into the design and budget. It may not eliminate every unforeseen condition—remodeling an existing home will always carry some unknowns—but it can reduce avoidable surprises.
Is a PSA the Same as the Construction Agreement?
No. They serve two different purposes.
The Professional Services Agreement covers the work required to develop and plan your project. The construction agreement covers the work required to build it.
Once the PSA phase is substantially complete, we meet with you to review the finished project plan. We discuss the scope of work, pricing, payment structure, timeline, logistics, communication, and any remaining concerns.
You will also meet your project manager and understand who will be coordinating the work before construction begins. After the design and production plan are approved, we prepare the construction agreement and walk through its details with you.
Does a PSA Require You to Move Forward With Construction?
Signing a Professional Services Agreement does not obligate you to enter into a construction agreement with Average Joe Construction.
The PSA is a separate phase of professional work. Should you choose not to begin construction immediately, you still retain the designs and plans completed through that agreement for future use.
You are responsible for the professional services completed and any approved outside costs incurred during the planning process, but you are not automatically committed to the building phase.
Why Not Simply Choose the Lowest Bid?
It makes sense to compare contractors before committing to a remodel, but the lowest price does not always represent the best value.
Two contractors may provide very different estimates because they are not necessarily including the same materials, preparation, craftsmanship, project management, or warranty coverage. A lower bid may also leave important details undefined or rely on allowances that do not reflect the finishes you actually want.
Our goal is not to produce the lowest possible number by reducing the quality of the work. We focus on creating a well-developed project that balances performance, craftsmanship, and your overall investment. When the design, selections, and scope are clearly defined first, you can evaluate the true project—not simply compare numbers built around different assumptions.
How Does a PSA Make Remodeling Easier?
A remodel includes many connected decisions. The layout can affect plumbing and electrical work. Material choices affect ordering and scheduling. Structural conditions can influence the design. A late selection may delay several other parts of construction. Without a defined pre-construction phase, those decisions often continue into the building process, when changes become more disruptive and expensive.
The PSA brings them forward.
By the time construction begins, you have a much clearer understanding of the design, scope, materials, expected investment, project team, and overall plan. Our team can then focus on executing the work instead of trying to design major parts of the project while actively building them. For busy homeowners, that structure can make the remodeling experience feel far more organized and manageable.
Is a Professional Services Agreement Worth It?
For a substantial home remodel, planning is not separate from the project. It is an essential part of the project. A Professional Services Agreement allows us to dedicate the necessary time to understanding your vision, developing the design, coordinating selections, investigating relevant conditions, and preparing dependable pricing.
It creates a stronger foundation for the construction agreement and gives everyone a clear reference point moving forward. Most importantly, it helps protect the vision you started with—so the home you imagined is much closer to the home you receive.
It gives us the opportunity to understand your goals, develop the design, work through selections, define the scope and create a realistic plan before construction begins. For homeowners taking on a substantial remodel in Johnson County or the greater Kansas City area, that preparation can make a big difference in how the rest of the experience feels.
