Sebastian Deck & Fence installs composite decks, wood decks, pool decks, and fencing for Grant-Valkaria homeowners, using materials rated for the Indian River Lagoon environment and managing all Brevard County permits from application to inspection - serving southern Brevard communities since 2015.

Grant-Valkaria properties near the Indian River Lagoon deal with salt air and moisture every day of the year - conditions that wear down untreated wood surfaces faster than most homeowners expect. Our composite deck installation uses capped composite boards and corrosion-resistant hardware so the finished deck holds up through years of lagoon-side exposure without the annual sealing and maintenance that wood decks require in this environment.
Pressure-treated lumber is a practical option for Grant-Valkaria homeowners who want the look and feel of natural wood and commit to regular maintenance. We use hot-dipped galvanized or stainless fasteners throughout - standard steel hardware corrodes noticeably within a season or two in the lagoon-side environment and is a primary reason older wood decks in this area become unsafe before the framing lumber itself gives out.
Vinyl fencing handles the salt air and moisture near the Indian River Lagoon significantly better than wood fencing. On larger Grant-Valkaria lots with sandy soil, vinyl posts set in deep concrete footings resist the post-lean that develops in wood fences after several rainy seasons. Vinyl does not rust, rot, or need painting - a practical choice for a rural waterfront property where ongoing maintenance time is limited.
Grant-Valkaria homes near the lagoon see standing water after heavy summer rain, and pool deck surfaces that sit on poorly drained sandy soil crack and heave faster than those on stable, well-drained ground. We assess drainage and soil conditions before building and choose materials suited to the specific moisture conditions on your property - not a one-size solution.
Proximity to the Indian River Lagoon and surrounding wetlands means mosquitoes and no-see-ums are persistent in Grant-Valkaria for most of the year. A screened enclosure over an existing patio slab or new deck turns outdoor space that would otherwise go unused in the evenings into a genuinely comfortable room - a popular upgrade on the larger rural lots common throughout this community.
Grant-Valkaria has homes spanning several decades of construction, with some dating back to the 1960s and 1970s. Decks built during the original construction of those older homes are well past their useful life, and the salt-air environment here accelerates deterioration compared to inland areas. We give you an honest assessment of whether targeted repairs or a full replacement is the right call - before any work starts.
Grant-Valkaria borders the Indian River Lagoon, one of the most biologically diverse estuaries in North America, and that proximity shapes nearly every outdoor home improvement decision in the community. Salt-laden air from the lagoon reaches properties well inland from the shoreline, corroding standard steel hardware, bleaching and checking wood surfaces, and accelerating the degradation of sealants and caulk joints faster than most homeowners account for. On waterfront lots with private docks and seawalls, the exposure is even more direct - a wood deck installed without corrosion-resistant fasteners and annual sealing on a canal-front property in Grant-Valkaria can become structurally unsafe within five to eight years, compared to a decade or more on a well-maintained inland deck.
Grant-Valkaria's housing stock spans several construction eras - from 1960s and 1970s concrete block homes to newer frame construction built in the 2000s and 2010s. Older CBS (concrete block structure) homes with stucco exteriors develop hairline cracks over time that are often the entry point for moisture intrusion. Many of those original properties also have outbuildings - sheds, workshops, detached garages - that need the same attention as the main house. The community is unincorporated, so all permitting goes through Brevard County Building and Development, which has different review requirements than the incorporated cities north of here. A contractor who knows the county's process avoids the permit delays that commonly push project start dates back by weeks.
Our crew works throughout Grant-Valkaria regularly, and we understand the local conditions that affect deck and fence work here. Grant-Valkaria is unincorporated Brevard County, so we handle county permits as a standard part of every project - not something we figure out as we go. We pull permits regularly through Brevard County Building and Development and know the documentation requirements, which keeps review timelines predictable for our customers.
Grant-Valkaria has a distinctly rural character that sets it apart from the suburbs north of here. Most properties sit on half-acre to multi-acre lots with mature oak, pine, and palm trees - and those trees drop significant debris onto roofs and into gutters while their root systems shift the ground under slabs and driveways over time. Many lots also have gravel or shell driveways and outbuildings alongside the main house, which affects how we stage materials and equipment during a job. Whether a property sits near the Grant Community Airpark or out on the lagoon side of the community, we make the drive and know the area.
We regularly serve homeowners in Palm Bay to the north and Micco just to the south. If your home is in Grant-Valkaria or a nearby southern Brevard community, we cover you.
Reach us by phone or through the contact form. We reply within one business day - typically the same day for phone calls. Tell us the type of project and a general idea of your property layout.
We visit your Grant-Valkaria property, assess soil and drainage conditions, and factor in the lagoon-adjacent environment when recommending materials. You get a written estimate with itemized costs - no obligation and no guesswork.
We submit the permit application to Brevard County Building and Development and track the review status. Plan for one to three weeks of county review time. We confirm the start date as soon as the permit is issued.
Construction takes three to seven working days for most projects. We coordinate the county inspection, walk the finished job with you, and clean the site before we leave. You do not need to be present during the build, though you are welcome to check in at any point.
We serve Grant-Valkaria and all of southern Brevard County - lagoon-side properties, rural lots, and everything in between. Reply within one business day, no obligation.
(772) 918-9088Grant-Valkaria is a small, unincorporated community in southern Brevard County, Florida, sitting between the Indian River Lagoon to the east and Interstate 95 to the west. The area has no downtown, no commercial center to speak of, and a population of roughly 4,000 to 5,000 - making it one of the quieter communities along Florida's Space Coast. What it does have is space. Properties here sit on half-acre to multi-acre lots, often with mature oaks, pines, and palms, gravel driveways, and outbuildings that give the community a distinctly rural feel that is uncommon in Brevard County. A number of homes sit directly on or very close to the lagoon, with private docks and direct water access. Some residents live in homes adjacent to the Grant Community Airpark runway - one of the more unusual features of the community, where homeowners taxi planes out of their garages.
The housing stock spans several decades, from early 1960s and 1970s concrete block homes to newer construction from the 2000s and 2010s. Residents tend to be long-term owner-occupants who chose Grant-Valkaria specifically for the rural, lagoon-adjacent setting - and who expect contractors to understand that context rather than show up with a suburban approach. The Grant Seafood Festival, an annual outdoor event and one of the longest-running community festivals in Brevard County, is a well-known landmark of local life. Neighboring communities include Micco to the south and Palm Bay to the north, both of which we also serve.
