Why Choose Scribe as Your General Contractor for Home Additions

here's how we work

The Process for Your Contractor Services 

Making sure you love it for the long-haul

Once complete, we’ll walk the space together to make sure everything meets expectations. Once you’ve had time to fully settle in, we’ll follow up a few months later to make sure it’s exactly as you imagined!

Final Walkthrough & Follow-Up

Construction is underway

We communicate regularly so you always know what’s happening and why. Projects are managed on a cost-plus basis, with transparent tracking of materials, subcontractors, and labor — allowing flexibility when real-life changes inevitably pop up.

Hammer Down

Final Selections and Cost-Plus Construction Agreement

Once preliminary estimate is approved & deposit is paid

Now we dial in the details. Selections are finalized, remaining pricing and scope are refined, and job-site logistics are planned. Your final agreement becomes the roadmap we’ll use to build your project.


Preliminary Estimate Development & Delivery

Typically delivered 2–4 weeks after the walkthrough

We’ll develop a detailed first draft of your project estimate and review it together. Once we’re aligned on the overall scope and budget, your approval and deposit officially moves your project into our construction pipeline.


For larger, more complex projects ONLY.

Some projects require additional site visits, subcontractor input, and detailed pricing to build an accurate estimate. For these projects, we’ll outline a preconstruction fee that covers this upfront work and is applied to your project if you move forward with us. 

Pre-Construction Agreement 

We see the space, you meet the team.

We’ll walk the space together to review existing conditions, logistics, and possibilities. This is where early ideas start taking shape and you get a feel for how we think, plan, and approach projects.

Walkthrough & Project Vision

Let’s make sure we’re a good fit.

You’ll start by filling out our inquiry form and scheduling a call to chat. We’ll talk through your goals, timeline, priorities, and answer early questions. If it feels right on both sides, we’ll schedule an on-site walkthrough.

Do I need permits for a home addition?

Yes, and we take care of that. Permit applications require drawn out plans and specs for your foundation up to your roof load. We handle that for you.

Can you help with both the addition and interior remodeling?

Yes! Our services are full-scope and include structural changes needed, as well as the interior remodeling and finishing!

Do you think I can pull off a DIY home addition?

We're gonna be straight with you — probably not. Home additions involve structural engineering, foundation work, electrical, plumbing, and a whole lot of code compliance. One misstep can create serious safety issues or cost you way more to fix down the line than if you'd just hired it out from the start. Unless you're an experienced contractor, an addition may not be the project to learn on.

That said, if you're set on being involved, our consulting services can help you understand what you're actually getting into and whether it makes sense to tackle parts of it yourself while leaving the critical stuff to the pros. We'd rather help you make a smart decision upfront than watch it become a costly mess later!

Frequently Asked Questions

Whether you know exactly what you want or you're still figuring it out, let's start with a conversation. We'll walk you through what's possible and what it looks like to do it together.
