Choose the Deck Scope Before Choosing the Boards

A deck project becomes easier to price when the first decision is not a color. The first decision is whether the existing deck needs a focused repair, a new walking surface, a structural rebuild or a different layout. Those options can look similar in a photograph while requiring very different work underneath. A Bellevue deck builder should be able to explain which parts of the existing assembly are expected to remain and which parts are included for replacement.

Repair, resurface or rebuild

A repair addresses a defined condition, such as a limited section of damaged framing, a stair problem or a railing that needs correction. Resurfacing keeps usable framing and replaces boards and related finish pieces. A rebuild removes structural components that should not remain. The estimate should not use these words interchangeably. It should identify the assumed condition of the frame and explain what happens if concealed deterioration appears during demolition.

Review the structure and the house connection

The surface receives most of the attention, but the supports, beams, joists, blocking and connection points determine how the deck feels in use. The scope should also describe how water is managed where the deck meets the house. That is especially important when adjacent siding work is planned, because the wall transition cannot be evaluated as an unrelated finish detail.

Whether drawings, review or input from another project professional are needed depends on the size, configuration and site conditions. That question should be resolved during planning rather than hidden behind a general allowance.

Plan stairs, railings and movement paths

Stair position changes circulation through the yard. Railing style affects sight lines, fastening and the amount of supporting work. A gate, privacy screen or transition to a patio door can change the layout as well. These decisions belong on the early plan because they influence both material quantities and framing. When a deck meets a new exterior or patio door, finished heights and clearances should be checked together.

Select the surface after the assembly is understood

Wood and composite decking each have tradeoffs. The useful comparison covers appearance, maintenance expectations, heat, traction, visible edges and the fastening details required by the selected product. The quote should separate the surface material from the framing and railing scope so an upgrade does not make the rest of the estimate harder to read.

Compare complete deck-builder estimates

Before choosing a proposal, compare demolition, disposal, framing assumptions, stairs, railings, surface material, trim, access and closeout. Confirm which selections are fixed and which remain allowances. A lower number is only useful when it covers the same work. For homeowners reviewing projects in the Bellevue service area, a clear scope is the best starting point for deciding whether the design, material level and construction plan belong in the same budget.

What a Bellevue Deck Quote Needs to Separate

A useful deck estimate starts by naming the actual job. Replacing surface boards is different from rebuilding framing, and both are different from laying out a new deck. The proposal should say what stays, what is removed and which conditions could change the scope after the existing deck is opened.

The structural portion should identify the framing, supports, connection to the house, stairs and railing work included in the number. The finish portion should identify the selected decking category, visible trim, fastening approach and any work needed where the deck meets siding or a patio door. Those details let a homeowner compare two deck-builder estimates on the same basis instead of comparing one complete scope with one surface-only price.

Material selection comes after that scope is understood. Cedar and composite surfaces differ in initial cost, appearance, maintenance and installation details, but neither material corrects weak framing underneath. Access and staging also belong in the estimate because moving demolition debris and long boards through a constrained property affects the work.

If the deck connects to planned door installation or siding work, the transitions should be coordinated before ordering. That keeps the deck, wall and opening work in one sequence rather than leaving each trade to solve the same edge separately.

Composite Material Planning

Composite decking is a major material line, so supplier pricing and selected board options are reviewed before the budget is locked.

Permit Planning

Permit Planning

Bellevue is strict about critical areas and steep slopes. Engineering, plan review and site constraints need to be addressed before exterior work starts

Sequenced Work

Coordinated Start Dates

We do not tear down your old deck in June and leave you staring at a muddy hole until August. Once we start digging footings we stay until the railings are done

Renova replaced aging wooden decking with composite for us and rebuilt our glass railing framing. Excellent work, very communicative. Also very accommodating of additional details we asked to add along the way. Highly recommended!

I recently hired this team to repair my roof after a fire and to build a deck above it, and I couldn’t be more pleased with the results. The project was complicated — after the fire, the roof began leaking, and they had to gut part of the ceiling to let everything dry out. They handled every step professionally and thoroughly. They rebuilt the damaged walls, repaired all the interior areas affected by water, replaced the trim, and repainted so everything looked fresh and seamless. They were also great about addressing every punch-list item, big or small. Throughout the entire process, they were on time, on budget, and consistently communicated what they were doing. The quality of their work really shows, and my home looks better than it did before the damage. Overall, I had a great experience and would highly recommend them to anyone needing reliable, skilled contractors.

These gentlemen were extremely professional, personal, and punctual. The three P's that every home owner is looking for. They were happy to handle all of our home repair jobs and did so quickly. From painting the walls and our deck, to grouping the floors in the bathroom, these guys handled it all with skill. They even did some touch up painting that we didn't request, they just saw it needed to be done and did it. I cannot say enough nice things about them.

We had an issue with water leaking in from the corner of our daylight basement, due to how the house was built there were multiple different issues with water leaking in our basement and it was a mess with black mold and water damage. We had Renova come out and look and they were very straightforward and transparent with what needed to be done, they were not just trying to get the job they were honest. They came all the way out from Seattle to Stanwood and did a very thorough job in repairing the black mold damage and they completely dug around the outside foundation of our daylight basement to water proof very thoroughly. It was a very big project but it needed to be done. We had them re paint our downstairs, build a 1,000 square foot back patio, build a new back deck, and we plan on using them to do more work. We are very happy with their hard work and attention to detail and highly recommend them.

Renova Contractors did a great job at building my deck, looks great and is definitely better than my old deck. I know a little bit about decks and I can say they definitely built me a deck that will withstand the rainy season in Seattle and won’t fall apart after five years. Thank you Mike, it was a pleasure working with your company.

Frequently Asked Questions

Answers about scope, estimates, scheduling, and project coordination

How much does a deck cost in Bellevue?

Many Bellevue decks range from $28,000 to $95,000 depending on size, material, stairs and railing. Elevated, engineered, waterproof or glass-railing decks can exceed $150,000.

When does a Bellevue deck need a permit?

Bellevue says a deck less than 30 inches above grade does not require a permit, while a deck more than 30 inches above grade goes through plan review. Repairs to stairs or guards also require a permit. We confirm the current path for the full site and structural scope before finalizing the design.

What is the real difference between Trex and TimberTech?

Both can work well, but they have different cores. Traditional Trex is a wood plastic composite, meaning it has wood fibers inside. Some TimberTech lines and Azek are PVC based, meaning they do not rely on wood fiber and can offer stronger moisture resistance. The right choice depends on budget, color, heat, slip feel, fastening system and maintenance expectations.

How do you choose framing lumber for a deck?

Framing lumber is selected for the required species, grade, treatment, dimensions and field condition. Each delivery still needs inspection for damage, excessive distortion and pieces that do not suit the planned span or connection; a retailer name alone does not establish quality.

Can I just put new composite boards over my old wood framing?

Sometimes, if the existing joists, beams, posts, ledger and connections are sound and their spacing fits the selected product requirements. Rot, damage or incompatible spacing may require repair or reframing. We inspect what is accessible first and identify any conditions that still need confirmation after the old boards come off.

How deep do the concrete footings have to go?

Footing size and depth depend on the approved structural design, loads, soil, slope and site conditions. A prescriptive minimum is not a substitute for the project plan. Steep or weak-soil conditions can require deeper foundations, engineered details or another approved support system.

Are cable railings safe for kids?

Cable guards still have to satisfy the applicable opening and load requirements after the system is installed and tensioned. Post spacing, terminal hardware, cable spacing and manufacturer instructions all affect performance, so the guard is designed and inspected as a complete system rather than judged by appearance alone.
